DETAILED DESCRIPTION Although the wound bed is known to be dynamic and heterogenous, most current treatments for wound healing are static and homogeneous such as Apligraf®, a wound healing treatment that is composed of Matrigel with dermal fibroblasts and epidermal keratinocytes. This limits the effectiveness of such therapies and does not address particularly challenging clinical situations such as chronic / non-healing wounds. The present disclosure describes a unique treatment approach comprising a patch that has controllable release of wound healing factors with optogenetically engineered cells. Since the light applied to a wound can be controlled, this allows for different wound healing factors to be delivered to different parts of the wound bed and at different times. This also allows for woundAttorney Docket No.: 2967398-000032-WO1 Date of Filing: August 16, 2024 healing factors to be delivered over longer time periods in an ongoing and dynamic fashion much like the natural progression of wound healing. In some embodiments, the wound is a scar or a closed wound. The light applied to a closed wound can be controlled as well, allowing for different wound healing factors to be delivered to different parts of the closed wound or scar tissue at different times. The wound healing device may comprise a first component made from a flowable material. In some embodiments, the wound healing device is capable of adopting the custom size, shape, and depth of a wound, in order to provide treatment to the entirety of the wound bed. Described herein are wound healing devices made capable of releasing a plurality of therapeutic agents in a customized fashion, e.g., in order to provide control of when and where certain therapeutic agents are released at the wound site. For example, the wound healing device may be loaded with cells capable of producing multiple different types of cytokines, which may be released depending on the stage of the wound healing process. In addition, the types of therapeutic agents to be released may vary depending on where along the wound site the cells are located. This tunable control over wound healing is helpful, as different regions of a wound may heal at different rates. In addition, the devices may include a biosensor to monitor healing, such as nitric oxide (NO) or TGF-β1. Current NO sensors have limitations such as high limit of detection, low selectivity, low stability over time and single detected point. Thus, the inventors have developed a micro-fabricated NO sensor arrays with high sensitivity and selectivity, which can achieve the multi-point NO mapping on the wound and direct the factor release. Therapeutic electrical stimulation directly to a wound is also proposed as s a further therapy provided by the device. These and other aspects of the disclosure are described in detail below.

For example, the skin may be torn, cut, or punctured (an “open” wound) or where blunt force trauma causes a contusion (a “closed” wound). In pathology, it can refer to a sharp injury which damages the epidermis of the skin. According to level of contamination, a wound can be classified as: Clean wound – made under sterile conditions where there are no organisms present, and the skin is likely to heal without complications. Contaminated wound – usually resulting from accidental injury; there are pathogenic organisms and foreign bodies in the wound. Infected wound – the wound has pathogenic organisms present and multiplying, exhibiting clinical signs of infection (yellow appearance, soreness, redness, oozing pus). Colonized wound – a wound containing pathogenic organisms, difficult to heal (e.g., bedsore). Wounds can also be categorized as acute or chronic, with the latter presenting particular challenges in the healing process. In an embodiment, an acute wound refers to a wound that quickly heals. In an embodiment, chronic wounds that are not healing should be investigated to find the causes; many microbiological agents may be responsible. The basic workup includes evaluating the wound, its extent and severity. Cultures are usually obtained both from the wound site and blood. X-rays are obtained and a tetanus shot may be administered if there is any doubt about prior vaccination. Bacterial infection of wound is a potential issue for nearly all wounds and can impede the healing process, even leading to life-threatening complications. Wound size is often the first and most important assessment of a wound. There are many methods known in the art for measuring the size of wounds (see, e.g., Int. Wound J.2016 Aug;Attorney Docket No.: 2967398-000032-WO1 Date of Filing: August 16, 2024 13(4): 540–553) A wound may be measured by, e.g., its linear dimensions (e.g., length and width). Exemplary methods of obtaining the dimensions of a wound include ruler-based methods, transparency tracings, and photography. In other instances, ascertaining the volume of a wound may be necessary. Exemplary methods of determining the volume of a wound include, e.g., ruler-based methods, casts (i.e., creating a mold), saline methods, stereophotogrammetry, and structured light readings (see, e.g., J. Wound Care 2009; 18(6): 250-253). The severity of a wound may be quantified by one or more wound assessment systems or scales known in the art. Exemplary wound assessments or scales include, e.g., Wagner System, Southampton Wound Scoring system, DEPA Scoring System, The University Of Texas System, Bates-Jensen Wound Assessment Tool TIME-H system, HEDI system, red-yellow-black-scheme (RYB) and others.

The extent of exudate may be described as heavy (e.g., wound dressing or bandage is soaked), medium, minimal, or absent. Wound Healing Processes To heal a wound, the body undertakes a series of actions collectively known as the wound healing process. Actions taken by the medical professional or patient may greatly improve the healing process. The overall treatment depends on the type, cause, and depth of the wound, and whether other structures beyond the skin (dermis) are involved. Treatment of recent lacerations involves examining, cleaning, and closing the wound. Minor wounds, like bruises, will heal on their own, with skin discoloration usually disappearing in 1–2 weeks. Abrasions, which are wounds with intact skin (non-penetration through dermis to subcutaneous fat), usually require no active treatment except keeping the area clean, initially with soap and water. Puncture wounds may be prone to infection depending on the depth of penetration. The entry of puncture wound is left open to allow for bacteria or debris to be removed from inside. Evidence to support the cleaning of wounds before closure is scant. For simple lacerations, cleaning can be accomplished using a number of different solutions, including tap water and sterile saline solution. Infection rates may be lower with the use of tap water in regions where water quality is high. Cleaning of a wound is also known as 'wound toilet'. It is not clear if delaying a shower following a surgery helps reduce complications related to wound healing. Evidence is insufficient to conclude whether cleaning wounds is beneficial or whether wound cleaning solutions (polyhexamethylene biguanide, aqueous oxygen peroxide, etc.) are better than sterile water or saline solutions to help venous leg ulcers heal. It is also uncertain whether the choice of cleaning solution or method of application makes any difference to venous leg ulcer healing. After this point in time, however, there is a theoretical concern of increased risks of infection if closed immediately. Thus, some healthcare providers may delay closure while others may be willing to immediately close up to 24 hours after the injury. If closure of a wound is decided upon a number of techniques can be used. These include bandages, a cyanoacrylate glue, staples, and sutures. Absorbable sutures have the benefitAttorney Docket No.: 2967398-000032-WO1 Date of Filing: August 16, 2024 over non absorbable sutures of not requiring removal. They are often preferred in children. Buffering the pH of lidocaine makes the injection less painful. Adhesive glue and sutures have comparable cosmetic outcomes for minor lacerations <5 cm in adults and children. The use of adhesive glue involves considerably less time for the doctor and less pain for the person. The wound opens at a slightly higher rate but there is less redness. The risk for infections (1.1%) is the same for both. Adhesive glue should not be used in areas of high tension or repetitive movements, such as joints or the posterior trunk. Split-thickness skin grafting (STSG) is also a surgical technique that features rapid wound closure, multiple possible donor sites with minimal morbidity. In the case of clean surgical wounds, there is no evidence that the use of topical antibiotics reduces infection rates in comparison with non-antibiotic ointment or no ointment at all. Antibiotic ointments can irritate the skin, slow healing, and greatly increase the risk of developing contact dermatitis and antibiotic resistance. Because of this, they should only be used when a person shows signs of infection and not as a preventative. Stages of Wound Healing Hemostatic Phase The hemostatic phase is initiated immediately after the occurrence of trauma to cease the loss of blood locally at the trauma site and restore vascular integrity, while globally maintaining blood circulation elsewhere in the body. The hemostatic phase is segmented into two complementary pathways, which act synergistically to restore normal blood flow to the area: (1) primary hemostasis, which consists of platelet degranulation, aggregation and ultimately, platelet plugging of the vascular injury; and (2) secondary hemostasis, which consists of the activation of a nonlinear network of serine proteases, ultimately leading to the polymerization of fibrinogen to form a fibrin mesh, thereby ceasing the loss of blood at the wound site. Upon the occurrence of trauma, the damaged endothelium is exposed to the circulation, thereby activating von Willebrand Factor (vWF), which initiates the recruitment of platelets and triggers their aggregation to form a platelet plug. Simultaneously, the damaged endothelium triggers the activation of the serine protease Factor VIIa (FVIIa), also referred to as tissue factor (TF) of the extrinsic pathway of coagulation. Factor VIIa then proteolytically catalyzes the formation the prothrombinase complex (Factor Xa), which modulates the activation of thrombin. ThrombinAttorney Docket No.: 2967398-000032-WO1 Date of Filing: August 16, 2024 subsequently catalyzes the cleavage of fibrinogen monomers to form the polymerized fibrin mesh at the wound site. The hemostatic phase typically occurs on the order of minutes to hours and is highly nonlinear. Multiple actors, e.g., activators and inhibitors, function in concert to modulate an appropriate hemostatic response requisite to the trauma incurred. For example, thrombin, in turn, is the most important platelet activator and activated platelets secrete fibrinogen, which facilitates formation of the fibrin clot. See Gale, A.J. Toxicol Pathol.2011, 39, 1, 273-280; and Smith, S.A. Crit Rev Biochem Mol Bio.2015, 50, 4, 326-336. Inflammatory Phase The inflammatory phase of the wound healing process begins within minutes of injury as activated platelets are recruited to the wound bed. Activated platelets secrete a myriad of factors upon degranulation that modulate the inflammatory response and that aid in the recruitment and coordination of various white blood cells to the wound bed for the removal of pathogens and debris. Serotonin secreted from platelet dense granules facilitates the localization of neutrophils at the epithelium. Activated platelets also express the integrin P-selectin, which modulates their interaction with various white blood cells, such as eosinophils, monocytes, and neutrophils. Activated platelets further secrete various chemokines and cytokines such as CCL3, CCL5, CXLCL1, CXCL4 (platelet factor 4 or PF4), CXCL5, CXCL5, CXCL7, CXCL8 (IL-8), CXCL12, which help to further amplify the inflammatory signal and recruit other cells to aid in the wound healing process and eliminate pathogens which may have entered the body as a result of trauma. See Seong-Hoon, Y. BioMed Research International.2016, 9060143 and Ellis, S. Current Dermatology Reports, 2018, 7, 350-358. Wound healing factors beneficial to the wound healing process in the inflammatory phase help modulate the inflammatory response, and recruit and coordinate the actions of white blood cells at the site of injury. Additional wound healing factors useful for secretion from the wound healing patch in the inflammatory phase are pro-inflammatory. Exemplary wound healing factors useful for secretion from the wound healing patch in the inflammatory phase include IL-12 and TNF-α. In some embodiments, the wound healing device spatiotemporally delivers IL-12 to accelerate the healing process in the inflammatory phase. In some embodiments, the wound healing device spatiotemporally delivers TNF-α to accelerate the healing process in the inflammatory phase.Attorney Docket No.: 2967398-000032-WO1 Date of Filing: August 16, 2024 Proliferative Phase Within 2-5 days from the time of injury, the inflammatory response subsides, and the wound healing process evolves into a proliferative phase, characterized by the repair and growth of a new vasculature, a new epithelium, and growth of a collagen-rich extracellular matrix (ECM) at the trauma site. Anti-inflammatory cells such as macrophages mediate the growth and repair process by secreting growth factors such as VEGF, leading to angiogenesis. Fibroblasts secrete IL-1, IL-6, and TNF-α, factors which propagate the initiation of the growth of new epithelial cells and promote collagen formation. Other critical wound healing factors include epidermal growth factor (EGF), keratinocyte growth factor (KGF), transforming growth factor- alpha (TGF-α), and transforming growth factor-beta (TGF-β), which assist in modulating the formation of new blood vessels and generation of the ECM. See Ellis, S. Current Dermatology Reports, 2018, 7, 350-358. Wound healing factors beneficial to the wound healing process in the proliferative phase are anti-inflammatory to promote the transition away from the inflammatory phase. Other wound factors that are beneficial include growth factors that assist in angiogenesis and re- epithelialization. Exemplary wound healing factors useful for secretion from the wound healing patch in the proliferative device include IL-10, VEGF, IL-1, IL-6, TNF-α, EGF, TGF-α, and TGF-β. In some embodiments, the wound healing device spatiotemporally delivers IL-10 to accelerate the healing process in the proliferative phase. In some embodiments, the wound healing device spatiotemporally delivers a wound healing factor selected from one or more of VEGF, IL-1, IL-6, TNF-α, EGF, TGF-α, and TGF-β. Remodeling Phase Weeks after injury, the revascularization is nearly complete, and the collagen-rich extracellular matrix is transformed into scar tissue. In the remodeling phase, myofibroblasts secrete wound healing factors such as TGF-β and matrix metalloproteinases (MMPs), which mediate the diminution in size of the wound area and the conversion of collagen in the extracellular matrix. See Ellis, S. Current Dermatology Reports, 2018, 7, 350-358. Wound healing factors beneficial to the wound healing process in the remodeling phase are factors that assist in the modification of the ECM and the conversion of type III collagen toAttorney Docket No.: 2967398-000032-WO1 Date of Filing: August 16, 2024 type I collagen. Wound healing factors useful for secretion from the wound healing patch include growth factors and matrix metalloproteinases. Exemplary wound healing factors useful for secretion from the wound healing patch in the remodeling phase include TGF-β and MMPs, e.g., MMP-1. In some embodiments, the wound healing device spatiotemporally delivers TGF-β to accelerate the healing process in the remodeling phase. In some embodiments, the wound healing device spatiotemporally delivers MMP-1 to accelerate the healing process in the remodeling phase. Acute Wounds Acute wounds include both surgical and non-surgical wounds, and in some cases from disease. Acute wounds may transition into chronic wounds, which are discussed below. Surgical wounds are at least initially classified as traumatic wounds. Non-surgical wounds can be caused by disease but, in most instances, are also traumatic wounds. Types of non-surgical trauma include car / train / bus / motorcycle / bicycle / ATV accidents, gunshot wounds, concussions, knife wounds, construction site accidents, industrial accidents, explosions, crushing injuries, and a host of other events leading to acute injury. Airway management, monitoring, and management of injuries are all key guidelines when it comes to medical trauma care. Airway management is a key component of emergency on-scene care. Using a systematic approach, first responders must access that a patient's airway is not blocked in order to ensure the patient gets enough circulation and remain as calm as they can. Monitoring patients and making sure their body does not go into shock is another essential guideline when it comes to medical trauma care. Nurses are required to watch over patients and check blood pressure, heart rate, etc. to make sure that patients are doing well and are not crashing. When it comes to managing injuries, head and neck injuries require the most care post-surgery. Head injuries are one of the major causes of trauma related death and disabilities worldwide. It is important for patients of head trauma to get CT scans post-surgery to ensure that there are no problems. Chronic Wounds A chronic wound is a wound that may not not heal in an orderly set of stages and in a predictable amount of time; wounds that do not heal within three months are often consideredAttorney Docket No.: 2967398-000032-WO1 Date of Filing: August 16, 2024 chronic. Chronic wounds seem to be detained in one or more of the phases of wound healing. For example, chronic wounds often remain in the inflammatory stage. To overcome that stage and jump-start the healing process, a number of factors need to be addressed such as bacterial burden, necrotic tissue, and moisture balance of the whole wound. In acute wounds, there may be a balance between production and degradation of molecules such as collagen; in chronic wounds this balance is lost and degradation may play an outsized role. Chronic wounds may never heal or may take years to do so. These wounds may cause patients emotional and physical stress. Acute and chronic wounds may be at opposite ends of a spectrum of wound-healing types that progress toward being healed at different rates. Chronic wound patients often report pain as dominant in their lives. It is recommended that healthcare providers handle the pain related to chronic wounds as a priority in chronic wound management (together with addressing the cause). Six out of ten venous leg ulcer patients experience pain with their ulcer, and similar trends are observed for other chronic wounds. Persistent pain (at night, at rest, and with activity) is the main problem for patients with chronic ulcers. Frustrations regarding ineffective analgesics and plans of care that they were unable to adhere to were also identified. In addition to poor circulation, neuropathy, and difficulty moving, factors that contribute to chronic wounds include systemic illnesses, age, and repeated trauma. The genetic skin disorders collectively known as epidermolysis bullosa display skin fragility and a tendency to develop chronic, non-healing wounds. Comorbid ailments that may contribute to the formation of chronic wounds include vasculitis (an inflammation of blood vessels), immune suppression, pyoderma gangrenosum, and diseases that cause ischemia. Immune suppression can be caused by illnesses or medical drugs used over a long period, for example steroids. Emotional stress can also negatively affect the healing of a wound, possibly by raising blood pressure and levels of cortisol, which lowers immunity. Another factor that may contribute to chronic wounds is age. The skin of older people may be more easily damaged, and older cells may not proliferate as fast and may not exhibit an adequate response to stress in terms of gene upregulation of stress-related proteins. In older cells, stress response genes may be overexpressed when the cell is not stressed, but when it is, the expression of these proteins is not upregulated by as much as in younger cells.Attorney Docket No.: 2967398-000032-WO1 Date of Filing: August 16, 2024 Comorbid factors that can lead to ischemia are especially likely to contribute to chronic wounds. Such factors include chronic fibrosis, edema, sickle cell disease, and peripheral artery disease such as by atherosclerosis. Repeated physical trauma plays a role in chronic wound formation by continually initiating the inflammatory cascade. The trauma may occur by accident, for example when a leg is repeatedly bumped against a wheelchair rest, or it may be due to intentional acts. Heroin users who lose venous access may resort to 'skin popping', or injecting the drug subcutaneously, which is highly damaging to tissue and frequently leads to chronic ulcers. Periwound skin damage caused by excessive amounts of exudate and other bodily fluids can perpetuate the non-healing status of chronic wounds. Maceration, excoriation, dry (fragile) skin, hyperkeratosis, callus and eczema are frequent problems that interfere with the integrity of periwound skin. They can create a gateway for infection as well as cause wound edge deterioration preventing wound closure. Chronic wounds may affect only the epidermis and dermis, or they may affect tissues all the way to the fascia. They may be caused by surgery or accidental trauma, or they may form as the result of systemic infection, vascular, immune, or nerve insufficiency, or comorbidities such as neoplasias or metabolic disorders. The reason a wound becomes chronic may be due in part to the body's ability to deal with the damage is overwhelmed by factors such as repeated trauma, continued pressure, ischemia, or illness. Though much progress has been accomplished in the study of chronic wounds lately, advances in the study of their healing have lagged behind expectations. This is partly because animal studies are difficult because animals do not get chronic wounds, since they usually have loose skin that quickly contracts, and they normally do not get old enough or have contributing diseases such as neuropathy or chronic debilitating illnesses. Nonetheless, current researchers now understand some of the major factors that lead to chronic wounds, among which are ischemia, reperfusion injury, and bacterial colonization. Factors influencing chronic wounds Ischemia is an important factor in the formation and persistence of wounds, especially when it occurs repetitively (as it usually does) or when combined with a patient's age. Ischemia causes tissue to become inflamed and cells to release factors that attract neutrophils such as interleukins, chemokines, leukotrienes, and complement factors.Attorney Docket No.: 2967398-000032-WO1 Date of Filing: August 16, 2024 While they fight pathogens, neutrophils also release inflammatory cytokines and enzymes that damage cells. One of their important jobs is to produce Reactive Oxygen Species (ROS) to kill bacteria, for which they use an enzyme called myeloperoxidase. The enzymes and ROS produced by neutrophils and other leukocytes damage cells and prevent cell proliferation and wound closure by damaging DNA, lipids, proteins, the extracellular matrix (ECM), and cytokines that speed healing. Neutrophils remain in chronic wounds for longer than they do in acute wounds, and contribute to the fact that chronic wounds have higher levels of inflammatory cytokines and ROS. Since wound fluid from chronic wounds has an excess of proteases and ROS, the fluid itself can inhibit healing by inhibiting cell growth and breaking down growth factors and proteins in the ECM. This impaired healing response is considered uncoordinated. However, soluble mediators of the immune system (growth factors), cell-based therapies and therapeutic chemicals can propagate coordinated healing. It has been suggested that the three fundamental factors underlying chronic wound pathogenesis are cellular and systemic changes of aging, repeated bouts of ischemia- reperfusion injury, and bacterial colonization with resulting inflammatory host response. Since more oxygen in the wound environment allows white blood cells to produce ROS to kill bacteria, patients with inadequate tissue oxygenation, for example those who suffered hypothermia during surgery, are at higher risk for infection. The host's immune response to the presence of bacteria prolongs inflammation, delays healing, and damages tissue. Infection can lead not only to chronic wounds but also to gangrene, loss of the infected limb, and death of the patient. More recently, an interplay between bacterial colonization and increases in reactive oxygen species leading to formation and production of biofilms has been shown to the generate chronic wounds. Like ischemia, bacterial colonization and infection damage tissue by causing a greater number of neutrophils to enter the wound site. In patients with chronic wounds, bacteria with resistances to antibiotics may have time to develop. In addition, patients that carry drug resistant bacterial strains such as methicillin-resistant Staphylococcus aureus (MRSA) have more chronic wounds. Chronic wounds also differ in makeup from acute wounds in that their levels of proteolytic enzymes such as elastase. and matrix metalloproteinases (MMPs) are higher, whileAttorney Docket No.: 2967398-000032-WO1 Date of Filing: August 16, 2024 their concentrations of growth factors such as Platelet-derived growth factor and Keratinocyte Growth Factor are lower. Since growth factors (GFs) are imperative in timely wound healing, inadequate GF levels may be an important factor in chronic wound formation. In chronic wounds, the formation and release of growth factors may be prevented, the factors may be sequestered and unable to perform their metabolic roles or degraded in excess by cellular or bacterial proteases. Chronic wounds such as diabetic and venous ulcers may also be caused by a failure of fibroblasts to produce adequate ECM proteins and by keratinocytes to epithelialize the wound. Fibroblast gene expression is different in chronic wounds than in acute wounds. Though most wounds require a certain level of elastase and proteases for proper healing, too high a concentration may be damaging. Leukocytes in the wound area release elastase, which increases inflammation, destroys tissue, proteoglycans, and collagen, and damages growth factors, fibronectin, and factors that inhibit proteases. The activity of elastase is increased by human serum albumin, which is the most abundant protein found in chronic wounds. However, chronic wounds with inadequate albumin may be especially unlikely to heal, so regulating the wound's levels of that protein may in the future can prove helpful in healing chronic wounds. Excess matrix metalloproteinases, which are released by leukocytes, may also cause wounds to become chronic. MMPs break down ECM molecules, growth factors, and protease inhibitors, and thus increase degradation while reducing construction, throwing the delicate compromise between production and degradation out of balance. Diagnosis The vast majority of chronic wounds can be classified into three categories: venous ulcers, diabetic, and pressure ulcers. A small number of wounds that do not fall into these categories may be due to causes such as radiation poisoning or ischemia. Venous ulcers, which usually occur in the legs, account for about 70% to 90% of chronic wounds and mostly affect the elderly. They are thought to be due to venous hypertension caused by improper function of valves that exist in the veins to prevent blood from flowing backward. Ischemia results from the dysfunction and, combined with reperfusion injury, causes the tissue damage that leads to the wounds. Another major cause of chronic wounds, diabetes, is increasing in prevalence. Diabetics have a 15% higher risk for amputation than the general population due to, for example, chronicAttorney Docket No.: 2967398-000032-WO1 Date of Filing: August 16, 2024 ulcers. Diabetes may cause neuropathy, which can inhibit nociception and the perception of pain. Thus patients may not initially notice small wounds to legs and feet, and may therefore fail to prevent infection or repeated injury. Further, diabetes causes immune compromise and damage to small blood vessels, preventing adequate oxygenation of tissue, which can cause chronic wounds. Pressure also plays a role in the formation of diabetic ulcers. Another leading type of chronic wounds is pressure ulcers, which usually occur in people with conditions such as paralysis that inhibit movement of body parts that are commonly subjected to pressure such as the heels, shoulder blades, and sacrum. Pressure ulcers are caused by ischemia that occurs when pressure on the tissue is greater than the pressure in capillaries, and thus restricts blood flow into the area. Muscle tissue, which needs more oxygen and nutrients than skin does, shows the worst effects from prolonged pressure. As in other chronic ulcers, reperfusion injury damages tissue. Treatment Though treatment of the different chronic wound types varies slightly, appropriate treatment seeks to address the problems at the root of chronic wounds, including ischemia, bacterial load, and imbalance of proteases. Periwound skin issues should be assessed, and their abatement included in a proposed treatment plan. Various methods exist to ameliorate these problems, including antibiotic and antibacterial use, debridement, irrigation, vacuum-assisted closure, warming, oxygenation, moist wound healing (the term pioneered by George D. Winter), removing mechanical stress, and adding cells or other materials to secrete or enhance levels of healing factors. It is uncertain whether intravenous metronidazole is useful in reducing foul smelling from malignant wounds. There is insufficient evidence to use silver-containing dressings or topical agents for the treatment of infected or contaminated chronic wounds. To lower the bacterial count in wounds, therapists may use topical antibiotics, which kill bacteria and can also help by keeping the wound environment moist, which is important for speeding the healing of chronic wounds. Some researchers have experimented with the use of tea tree oil, an antibacterial agent which also has anti-inflammatory effects. Disinfectants are contraindicated because they damage tissues and delay wound contraction. Further, they are rendered ineffective by organic matter in wounds like blood and exudate and are thus not useful in open wounds.Attorney Docket No.: 2967398-000032-WO1 Date of Filing: August 16, 2024 A greater amount of exudate and necrotic tissue in a wound increases likelihood of infection by serving as a medium for bacterial growth away from the host's defenses. Since bacteria thrive on dead tissue, wounds are often surgically debrided to remove the devitalized tissue. Debridement and drainage of wound fluid are an especially important part of the treatment for diabetic ulcers, which may create the need for amputation if infection gets out of control. Mechanical removal of bacteria and devitalized tissue is also the idea behind wound irrigation, which is accomplished using pulsed lavage. Removing necrotic or devitalized tissue is also the aim of maggot therapy, the intentional introduction by a health care practitioner of live, disinfected maggots into non-healing wounds. Maggots dissolve only necrotic, infected tissue; disinfect the wound by killing bacteria; and stimulate wound healing. Maggot therapy has been shown to accelerate debridement of necrotic wounds and reduce the bacterial load of the wound, leading to earlier healing, reduced wound odor and less pain. The combination and interactions of these actions make maggots an extremely potent tool in chronic wound care. Negative pressure wound therapy (NPWT) is a treatment that improves ischemic tissues and removes wound fluid used by bacteria. This therapy, also known as vacuum-assisted closure, reduces swelling in tissues, which brings more blood and nutrients to the area, as does the negative pressure itself. The treatment also decompresses tissues and alters the shape of cells, causes them to express different mRNAs and to proliferate and produce ECM molecules. Recent technological advancements produced novel approaches such as self-adaptive wound dressings that rely on properties of smart polymers sensitive to changes in humidity levels. The dressing delivers absorption or hydration as needed over each independent wound area and aids in the natural process of autolytic debridement. It effectively removes liquefied slough and necrotic tissue, disintegrated bacterial biofilm as well as harmful exudate components, known to slow the healing process. The treatment also reduces bacterial load by effective evacuation and immobilization of microorganisms from the wound bed, and subsequent chemical binding of available water that is necessary for their replication. Self-adaptive dressings protect periwound skin from extrinsic factors and infection while regulating moisture balance over vulnerable skin around the wound. Persistent chronic pain associated with non-healing wounds is caused by tissue (nociceptive) or nerve (neuropathic) damage and is influenced by dressing changes andAttorney Docket No.: 2967398-000032-WO1 Date of Filing: August 16, 2024 chronic inflammation. Chronic wounds take a long time to heal and patients can suffer from chronic wounds for many years. Chronic wound healing may be compromised by coexisting underlying conditions, such as venous valve backflow, peripheral vascular disease, uncontrolled edema and diabetes mellitus. If wound pain is not assessed and documented, it may be ignored and / or not addressed properly. It is important to remember that increased wound pain may be an indicator of wound complications that need treatment, and therefore practitioners must constantly reassess the wound as well as the associated pain. Optimal management of wounds requires holistic assessment. Documentation of the patient's pain experience is critical and may range from the use of a patient diary, (which should be patient driven), to recording pain entirely by the healthcare professional or caregiver. Effective communication between the patient and the healthcare team is fundamental to this holistic approach. The more frequently healthcare professionals measure pain, the greater the likelihood of introducing or changing pain management practices. At present there are few local options for the treatment of persistent pain, whilst managing the exudate levels present in many chronic wounds. Important properties of such local options are that they provide an optimal wound healing environment, while providing a constant local low dose release of ibuprofen during wear-time. If local treatment does not provide adequate pain reduction, it may be necessary for patients with chronic painful wounds to be prescribed additional systemic treatment for the physical component of their pain. Clinicians should consult with their prescribing colleagues referring to the WHO pain relief ladder of systemic treatment options for guidance. For every pharmacological intervention there are possible benefits and adverse events that the prescribing clinician will need to consider in conjunction with the wound care treatment team. Blood vessels constrict in tissue that becomes cold and dilate in warm tissue, altering blood flow to the area. Thus, keeping the tissues warm is probably necessary to fight both infection and ischemia. Some healthcare professionals use ‘radiant bandages’ to keep the area warm, and care must be taken during surgery to prevent hypothermia, which increases rates of post-surgical infection.Attorney Docket No.: 2967398-000032-WO1 Date of Filing: August 16, 2024 Underlying ischemia may also be treated surgically by arterial revascularization, for example in diabetic ulcers, and patients with venous ulcers may undergo surgery to correct vein dysfunction. Diabetics that are not candidates for surgery (and others) may also have their tissue oxygenation increased by Hyperbaric Oxygen Therapy, or HBOT, which may provide a short- term improvement in healing by improving the oxygenated blood supply to the wound. In addition to killing bacteria, higher oxygen content in tissues speeds growth factor production, fibroblast growth, and angiogenesis. However, increased oxygen levels also indicates increased production of ROS. Antioxidants, molecules that can lose an electron to free radicals without themselves becoming radicals, can lower levels of oxidants in the body and have been used with some success in wound healing. Low level laser therapy has been repeatedly shown to significantly reduce the size and severity of diabetic ulcers as well as other pressure ulcers. Pressure wounds are often the result of local ischemia from the increased pressure. Increased pressure also plays a role in many diabetic foot ulcerations as changes due to the disease causes the foot to suffer limited joint mobility and creates pressure points on the bottom of the foot. Effective measures to treat this includes a surgical procedure called the gastrocnemius recession in which the calf muscle is lengthened to decrease the fulcrum created by this muscle and resulting in a decrease in plantar forefoot pressure. Since chronic wounds underexpress growth factors necessary for healing tissue, chronic wound healing may be speeded by replacing or stimulating those factors and by preventing the excessive formation of proteases like elastase that break them down. One way to increase growth factor concentrations in wounds is to apply the growth factors directly. This generally takes many repetitions and requires large amounts of the factors, although biomaterials are being developed that control the delivery of growth factors over time. Another way is to spread onto the wound a gel of the patient's own blood platelets, which then secrete growth factors such as vascular endothelial growth factor (VEGF), insulin-like growth factor 1–2 (IGF), PDGF, transforming growth factor-β (TGF-β), and epidermal growth factor (EGF). Other treatments include implanting cultured keratinocytes into the wound to reepithelialize it and culturing and implanting fibroblasts into wounds. Some patients are treatedAttorney Docket No.: 2967398-000032-WO1 Date of Filing: August 16, 2024 with artificial skin substitutes that have fibroblasts and keratinocytes in a matrix of collagen to replicate skin and release growth factors. In other cases, skin from cadavers is grafted onto wounds, providing a cover to keep out bacteria and preventing the buildup of too much granulation tissue, which can lead to excessive scarring. Though the allograft (skin transplanted from a member of the same species) is replaced by granulation tissue and is not actually incorporated into the healing wound, it encourages cellular proliferation and provides a structure for epithelial cells to crawl across. On the most difficult chronic wounds, allografts may not work, requiring skin grafts from elsewhere on the patient, which can cause pain and further stress on the patient's system. Collagen dressings are another way to provide the matrix for cellular proliferation and migration, while also keeping the wound moist and absorbing exudate. Additionally, collagen has been shown to be chemotactic to human blood monocytes, which can enter the wound site and transform into beneficial wound-healing cells. Since levels of protease inhibitors are lowered in chronic wounds, some researchers are seeking ways to heal tissues by replacing these inhibitors in them. Secretory leukocyte protease inhibitor (SLPI), which inhibits not only proteases but also inflammation and microorganisms like viruses, bacteria, and fungi, may prove to be an effective treatment. Research into hormones and wound healing has shown estrogen to speed wound healing in elderly humans and in animals that have had their ovaries removed, possibly by preventing excess neutrophils from entering the wound and releasing elastase. Thus, the use of estrogen is a future possibility for treating chronic wounds. The rate of treating of a wound may be measured or assessed according to methods known in the art.

Closed Wounds in an aspect, the present disclosure features a closed wound healing device for use in treating a closed wound. Closed wounds are wounds that may be characterized by a contusion or ecchymosis, wherein the integrity of the skin remains intact and is not torn, cut, or otherwise punctured, as in the case of open wounds. Closed wounds may be the result of blunt force trauma that does not damage the epidermal layer of the skin. Blunt force trauma may occur when anAttorney Docket No.: 2967398-000032-WO1 Date of Filing: August 16, 2024 individual suffers from a collision with a blunt object, e.g., as result of a vehicle accident, an exercise or athletic-related collision, or a fall. A closed wound may also comprise a scar, a skin patch, or other damage or abnormality in the tissue (e.g., dermal tissue). In an embodiment, the closed wound comprises a contusion. Contusions may be rated on an increasing integer scale from 0-5, which characterizes the risk of morbidity and fatality associated with the contusion. Contusions may be assessed by, e.g., their physical presentation, injury to organs and body compartments, and determination of the inflammatory response. In an embodiment, the contusion is characterized by a harm score of 0, indicating that the risk of morbidity and fatality is effectively 0. In an embodiment, the contusion is characterized by a harm score of 1, indicating that the risk of morbidity and fatality is minor. In an embodiment In an embodiment, the contusion is characterized by a harm score of 1, indicating that the risk of morbidity and fatality is moderate. In an embodiment In an embodiment, the contusion is characterized by a harm score of 1, indicating that the risk of morbidity and fatality is high. In an embodiment In an embodiment, the contusion is characterized by a harm score of 1, indicating that the risk of morbidity and fatality is extremely high. See Urakov, A. IP International Journal of Comprehensive and Advanced Pharmacology.2020, 5, 1, 1-5. Closed wounds may be equally as dangerous to livelihood as puncture wounds. For example, blunt force trauma may result in traumatic brain injury resulting in intracranial hemorrhage and permanent neurological impairment; or, blunt force injury may cause thoracic injury, resulting in damage to the lung, heart and / or pleural cavity impacting breathing, blood oxygenation, and proper cardiac function. In an embodiment, the closed wound comprises a scar. The scarring process is an integral part of the stages of wound healing as the body repairs and replaces damaged tissue through the action of fibroblasts which help to deposit extracellular matrix proteins such as fibronectin, convert immature type III collagen to type I collagen, and seed new epithelial cells at the injury site. However, the scarring process may become pathological when the underlying mechanisms modulating the fibrotic process are not in equilibrium. For example, hypertrophic scars are scars characterized by an overabundance of collagen relative to a nonpathological scar. It is suggested that hypertrophic scars arise from hyperactive TGF-β production, e.g., from macrophages, during the proliferative stage of wound healing. The closed wound healing device, as contemplated herein, is useful for treating a closed wound,Attorney Docket No.: 2967398-000032-WO1 Date of Filing: August 16, 2024 wherein the closed wound is a hypertrophic scar.

In an embodiment, the closed wound healing device modulates the activity of a matrix metalloproteinase (MMP),Attorney Docket No.: 2967398-000032-WO1 Date of Filing: August 16, 2024 wherein the MMP is MMP9. In an embodiment, the closed wound healing device is useful for treating a scar, wherein the scar is a hypertrophic scar, by modulating the activity of a matrix metalloproteinase (MMP), wherein the MMP is MMP13. Keloids or keloidal scars are scars characterized by fibrous hypertrophy of granulation tissue, which extends beyond the initial area of the wound. Certain demographic groups, such as individuals of African, Asian, and Latino origin are more susceptible to developing keloidal formations in response to traumatic injury. Although a specific locus has not been identified, growing scientific consensus has emerged that there exists a prominent genetic etiological component in developing keloids. In an embodiment, the closed wound healing device useful for treating a keloid or keloidal scar comprises the transdermal delivery of one or more of the wound factors selected from IL-1β, IL-4, IL-6, IL-8, IL-10, IL-12, IL-17, IL-18, IL-22, IL-23, TNF-α, TGF-β, and IFN- γ, MMP, VEGF, EGF, PDGF, and FGF.

Optogenetics and Engineered CellsAttorney Docket No.: 2967398-000032-WO1 Date of Filing: August 16, 2024 Optogenetics is a biological technique useful for controlling the activity of neurons or other cell types with light. This control is achieved by expression of light-sensitive ion channels, pumps or enzymes specifically in the target cells. On the level of individual cells, light-activated enzymes and transcription factors may allow for precise control of biochemical signaling pathways. In systems neuroscience, the ability to control the activity of a genetically defined set of neurons has been used to understand their contribution to decision making, learning, fear memory, mating and addiction. In a first medical application of optogenetic technology, vision was partially restored in a blind patient. In a broader sense, optogenetics also includes methods to record cellular activity with genetically encoded indicators. Optogenetics may provide millisecond-scale temporal precision which allows the experimenter to keep pace with fast biological information processing (for example, in probing the causal role of specific action potential patterns in defined neurons). Indeed, to probe the neural code, optogenetics may operate on the millisecond timescale to allow addition or deletion of precise activity patterns within specific cells in the brains of intact animals, such as mammals (e.g., a human). By comparison, the temporal precision of traditional genetic manipulations (employed to probe the causal role of specific genes within cells, via "loss-of-function" or "gain of function" changes in these genes) is rather slow, from hours or days to months. It may also be important to also have fast readouts in optogenetics that can keep pace with the optical control. This can be done with electrical recordings ("optrodes") or with reporter proteins that are biosensors, where scientists have fused fluorescent proteins to detector proteins. Additionally, beyond its scientific impact optogenetics represents an important case study in the value of both ecological conservation (as many of the key tools of optogenetics arise from microbial organisms occupying specialized environmental niches), and in the importance of pure basic science as these opsins were studied over decades for their own sake by biophysicists and microbiologists. The hallmark of optogenetics therefore is introduction of fast light-activated channels, pumps, and enzymes that allow temporally precise manipulation of electrical and biochemical events while maintaining cell-type resolution through the use of specific targeting mechanisms. Among the microbial opsins which can be used to investigate the function of neural systems are the channelrhodopsins (ChR2, ChR1, VChR1, and SFOs) to excite neurons and anion- conducting channelrhodopsins for light-induced inhibition. Indirectly light-controlled potassiumAttorney Docket No.: 2967398-000032-WO1 Date of Filing: August 16, 2024 channels have recently been engineered to prevent action potential generation in neurons during blue light illumination. Light-driven ion pumps are also used to inhibit neuronal activity, e.g., halorhodopsin (NpHR), enhanced halorhodopsins (eNpHR2.0 and eNpHR3.0), archaerhodopsin (Arch), fungal opsins (Mac) and enhanced bacteriorhodopsin (eBR). Optogenetic control of well-defined biochemical events within behaving mammals is now also possible. Building on prior work fusing vertebrate opsins to specific G-protein coupled receptors a family of chimeric single-component optogenetic tools was created that allowed researchers to manipulate within behaving mammals the concentration of defined intracellular messengers such as cAMP and IP3 in targeted cells. Other biochemical approaches to optogenetics (crucially, with tools that displayed low activity in the dark) followed soon thereafter, when optical control over small GTPases and adenylyl cyclase was achieved in cultured cells using novel strategies from several different laboratories. Photoactivated adenylyl cyclases have been discovered in fungi and successfully used to control cAMP levels in mammalian neurons. This emerging repertoire of optogenetic actuators now allows cell-type- specific and temporally precise control of multiple axes of cellular function within intact animals. Another important component in many optogenetic systems is hardware (e.g., integrated fiberoptic and solid-state light sources) to allow specific cell types, even deep within the brain, to be controlled in freely behaving animals. Most commonly, the latter is now often achieved using the fiberoptic-coupled diode technology introduced in 2007, though to avoid use of implanted electrodes, researchers have engineered ways to inscribe a "window" made of zirconia that has been modified to be transparent and implanted in mice skulls, to allow optical waves to penetrate more deeply to stimulate or inhibit individual neurons. To stimulate superficial brain areas such as the cerebral cortex, optical fibers or LEDs can be directly mounted to the skull of the animal. More deeply implanted optical fibers have been used to deliver light to deeper brain areas. Complementary to fiber-tethered approaches, completely wireless techniques have been developed utilizing wirelessly delivered power to headborne LEDs for unhindered study of complex behaviors in freely behaving organisms. Recent studies have examined the use of organic LEDs (OLEDs) as stimuli for optogenetics. The precise and controlled stimulation of neurons expressing microbial opsin has been demonstrated in-vitro on a time scale in the order of a millisecond. Pulsed mode operation allows neural stimulation within compatible lowAttorney Docket No.: 2967398-000032-WO1 Date of Filing: August 16, 2024 temperature. Moreover, organic light-emitting diodes (OLED) are suitable for implantation in the brain for their very thin thickness which can be less than 1 µm. Optogenetics also necessarily includes the development of genetic targeting strategies such as cell-specific promoters or other customized conditionally-active viruses, to deliver the light-sensitive probes to specific populations of neurons in the brain of living animals (e.g., worms, fruit flies, mice, rats, and monkeys). In invertebrates such as worms and fruit flies, some amount of all-trans-retinal (ATR) is supplemented with food. A key advantage of microbial opsins as noted above is that they are fully functional without the addition of exogenous co- factors in vertebrates. The technique of using optogenetics is flexible and adaptable to the experimenter's needs. For starters, experimenters genetically engineer a microbial opsin based on the gating properties (rate of excitability, refractory period, etc.) required for the experiment. There is a challenge in introducing the microbial opsin, an optogenetic actuator, into a specific region of the organism in question. A rudimentary approach is to introduce an engineered viral vector that contains the optogenetic actuator gene attached to a recognizable promoter such as CAMKIIα. This allows for some level of specificity as cells that already contain and can translate the given promoter will be infected with the viral vector and hopefully express the optogenetic actuator gene. Another approach is the creation of transgenic mice where the optogenetic actuator gene is introduced into mice zygotes with a given promoter, most commonly Thy1. Introduction of the optogenetic actuator at an early stage allows for a larger genetic code to be incorporated and as a result, increases the specificity of cells to be infected. A third approach that has been developed is creating transgenic mice with Cre recombinase, an enzyme that catalyzes recombination between two lox-P sites. Then by introducing an engineered viral vector containing the optogenetic actuator gene in between two lox-P sites, only the cells containing the Cre recombinase will express the microbial opsin. This last technique has allowed for multiple modified optogenetic actuators to be used without the need to create a whole line of transgenic animals every time a new microbial opsin is needed. After the introduction and expression of the microbial opsin, depending on the type of analysis being performed, application of light can be placed at the terminal ends or the main region where the infected cells are situated. Light stimulation can be performed with a vast array ofAttorney Docket No.: 2967398-000032-WO1 Date of Filing: August 16, 2024 instruments from light-emitting diodes (LEDs) or diode-pumped solid-state laser (DPSS). These light sources are most commonly connected to a computer through a fiber optic cable. Recent advances include the advent of wireless head-mounted devices that also apply LED to targeted areas and as a result give the animal more freedom of mobility to reproduce in vivo results. Moreover, fiber-based approaches can now offer simultaneous single-cellular resolution optical stimulation and Calcium imaging. This enables researchers to visualize and manipulate the activity of single neurons while preserving naturalistic animal behaviours. Further, these techniques allow one to record in multiple deep brain regions at the same using GRIN lenses connected via optical fiber to an externally positioned photodetector and photostimulator. Moreover, mathematical modelling shows that selective expression of opsin in specific cell types can dramatically alter the dynamical behavior of the neural circuitry. In particular, optogenetic stimulation that preferentially targets inhibitory cells can transform the excitability of the neural tissue from Type 1 — where neurons operate as integrators — to Type 2 where neurons operate as resonators. Type 1 excitable media sustain propagating waves of activity whereas Type 2 excitable media do not. The transformation from one to the other explains how constant optical stimulation of primate motor cortex elicits gamma-band (40–80 Hz) oscillations in the manner of a Type 2 excitable medium. Yet those same oscillations propagate far into the surrounding tissue in the manner of a Type 1 excitable medium. It may be difficult to target opsin to defined subcellular compartments, e.g., the plasma membrane, synaptic vesicles, or mitochondria. Restricting the opsin to specific regions of the plasma membrane such as dendrites, somata or axon terminals would provide a more robust understanding of neuronal circuitry. Analogously to how natural light-gated ion channels such as channelrhodopsin-2 allows optical control of ion flux, which is especially useful in neuroscience, natural light-controlled signal transduction proteins also allow optical control of biochemical pathways, including both second-messenger generation and protein-protein interactions, which is especially useful in studying cell and developmental biology. In 2002, the first example of using photoproteins from another organism for controlling a biochemical pathway was demonstrated using the light- induced interaction between plant phytochrome and phytochrome-interacting factor (PIF) to control gene transcription in yeast. By fusing phytochrome to a DNA-binding domain and PIF toAttorney Docket No.: 2967398-000032-WO1 Date of Filing: August 16, 2024 a transcriptional activation domain, transcriptional activation of genes recognized by the DNA- binding domain could be induced by light. This study anticipated aspects of the later development of optogenetics in the brain, for example, by suggesting that "Directed light delivery by fiber optics has the potential to target selected cells or tissues, even within larger, more-opaque organisms." The literature has been inconsistent as to whether control of cellular biochemistry with photoproteins should be subsumed within the definition of optogenetics, as optogenetics in common usage refers specifically to the control of neuronal firing with opsins, and as control of neuronal firing with opsins postdates and utilizes distinct mechanisms from control of cellular biochemistry with photoproteins. In addition to phytochromes, which are found in plants and cyanobacteria, LOV domains (Light-oxygen-voltage-sensing domain) from plants and yeast and cryptochrome domains from plants are other natural photosensory domains that have been used for optical control of biochemical pathways in cells. In addition, a synthetic photosensory domain has been engineered from the fluorescent protein Dronpa for optical control of biochemical pathways. In photosensory domains, light absorption is either coupled to a change in protein-protein interactions (in the case of phytochromes, some LOV domains, cryptochromes, and Dronpa mutants) or a conformational change that exposes a linked protein segment or alters the activity of a linked protein domain (in the case of phytochromes and some LOV domains). Light- regulated protein-protein interactions can then be used to recruit proteins to DNA, for example to induce gene transcription or DNA modifications, or to the plasma membrane, for example to activate resident signaling proteins. CRY2 also clusters when active, so has been fused with signaling domains and subsequently photoactivated to allow for clustering-based activation. The LOV2 domain of Avena sativa (common oat) has been used to expose short peptides or an active protein domain in a light-dependent manner. Introduction of this LOV domain into another protein can regulate function through light induced peptide disorder. The asLOV2 protein, which optogenetically exposes a peptide, has also been used as a scaffold for several synthetic light induced dimerization and light induced dissociation systems (iLID and LOVTRAP, respectively).]The systems can be used to control proteins through a protein splitting strategy. Photodissociable Dronpa domains have also been used to cage a protein active site in the dark, uncage it after cyan light illumination, and recage it after violet light illumination.Attorney Docket No.: 2967398-000032-WO1 Date of Filing: August 16, 2024 The ability to optically control signals for various time durations is being explored to elucidate how cell signaling pathways convert signal duration and response to different outputs. Natural signaling cascades are capable of responding with different outputs to differences in stimulus timing duration and dynamics.

[0147] For example, treating PC12 cells with epidermal growth factor (EGF, inducing a transient profile of ERK activity) leads to cellular proliferation whereas introduction of nerve growth factor (NGF, inducing a sustained profile of ERK activity) leads to differentiation into neuron-like cells.

[0148] This behavior was initially characterized using EGF and NGF application, but the finding has been partially replicated with optical inputs. In addition, a rapid negative feedback loop in the RAF-MEK-ERK pathway was discovered using pulsatile activation of a photoswitchable RAF engineered with photodissociable Dronpa domains. Red and NIR light-responsive Phytochromes are photoreceptors that utilize tetrapyrrole chromophores such as biliverdin IXα (BV) or phycocyanobilin (PCB) to absorb red and NIR light and induce reversible conformational changes in the protein structure. One common photoreceptor used to control gene expression is Phytochrome protein B (PhyB), and its interaction partner Phytochrome-Interacting Factor 3 (PIF3) that dimerise under red light and dissociate under far-red light. By fusing DNA- Binding Domains (DBDs) and transActivation Domains (ADs) to distinct PhyB and PIF modules, red light inducible two-hybrid systems have been used to activate gene expression in yeast and mammalian cells. In bacteria, Two-Component signaling Systems (TCSs) comprising of a natural or engineered light-responsive kinase and a downstream response regulator are used. For example, Cph8 is a light-responsive kinase engineered by replacing the osmosensory domain of a membrane-bound histidine kinase with the Cph1 phytochrome. In the absence of light, Cph8 phosphorylates the transcription factor OmpR and promotes gene expression, while in the presence of red light the kinase activity and gene expression are inactivated. The natural cyanobacteriochrome TCS and CcaS / CcaR regulate gene expression according to green and red light in a similar fashion. Most red light-responsive gene expression systems require a PCB chromophore to function. PCB can be added to the growth media and taken up by cells or, alternatively, geneAttorney Docket No.: 2967398-000032-WO1 Date of Filing: August 16, 2024 cassettes encoding enzymes for PCB biosynthesis are used to enable cells to synthesize PCB from intracellular heme. NIR-responsive phytochromes utilize BV chromophores that are produced endogenously by mammalian cells. Such NIR-responsive gene expression systems can be derived from BphP1 and PpsR2 proteins, the latter being sequestered by BphP1 in NIR light and released in the presence of red light or absence of light. NIR-responsive transcription factors have been created by fusing BphP1 and PpsR2 to DBDs and Ads. These constructs activate reporter gene expression in bacteria, mammalian cells, and mice. LOV domain proteins and cryptochromes are two distinct protein families that differ in their protein architecture, yet both use blue light absorbing flavin chromophores to induce conformational changes in the protein. Cryptochrome-based systems are based primarily on the interaction of Cryptochrome protein 2 (CRY2) with Cryptochrome-Interacting Basic-helix-loop- helix protein (CIB1). Blue light responsive elements Blue light-responsive transcription systems are also known, such as TCS implementing an engineered light-sensitive kinase called YF1. This construct was created by replacing an oxygen-sensing domain of a natural kinase with the YvtA LOV domain. In the absence of light, YF1 phosphorylated and activated a transcription factor, whereas in the presence of blue-light, kinase activity and gene expression were inactivated. Using this system as a model, a bacterial repression switch, pDusk, and activation switch, pDawn, were developed. Blue light-regulated gene expression in eukaryotic cells, however, is typically controlled with photoactivatable transcription factors. Flavin-binding, Kelch domain, F-box protein (FKF1) and its interaction partner GIGANTEA (GI) can be fused to ADs and DBDs and for blue light-activated transcription control in mammalian cells. Similar light-activated effector proteins based on CRY2 / CIB1, and smaller LOV domain proteins also function in this way. Another is Vivid (VVD), a photoreceptor that rapidly and reversibly fo...
