Description

Composition for inducing macrophage polarization comprising porphyrin-based metal-organic framework and use thereof

[0001] The present invention relates to a composition for inducing macrophage polarization, comprising a porphyrin-based metal-organic framework (MOF), and its use.

[0002] The innate immune response is the body's first line of defense against invading pathogens, also known as nonspecific immunity. Neutrophils, monocytes, and macrophages are involved in the innate immune response, and it responds rapidly to pathogen invasion or infection, regardless of the type of pathogen or prior infection experience.

[0003] In particular, macrophages are cells distributed throughout all tissues in the body and are responsible for immunity, and are involved in the removal of invading pathogens, the removal of virus-infected autologous cells and cancer cells, and the induction of inflammatory responses. Macrophages can be divided into tissue-resident macrophages that differentiate from yolk sacs or fetal livers during development, and monocyte-derived macrophages that differentiate from monocytes in the blood (differentiated from bone marrow cells) in response to inflammatory responses or pathogen invasion.

[0004] Tissue-derived macrophages and monocyte-derived macrophages can differentiate into M1 macrophages and M2 macrophages, which act on different immune responses by cytokines. Cytokines are proteins involved in the transmission of information between cells, and are secreted by a chain of immune responses from cells that recognize pathogens or infections, and promote the differentiation and proliferation of cells that are responsible for the immune response, such as helper T cells (Th cells), B cells, and macrophages. M1 macrophages are induced by Th1 cell cytokines such as IFN-γ and TNF-α, and act to induce Th1 responses, induce inflammation, and suppress cancer growth. M2 macrophages are induced by Th2 cell cytokines such as IL-4 and IL-10, and act to induce Th2 responses, suppress inflammation, and repair damaged tissue. In this way, bone marrow-derived macrophages and monocyte-derived macrophages can differentiate into M1 or M2 macrophages, which have different functions depending on the type of cytokine.

[0005] These macrophages require time to differentiate, proliferate, and become activated by cytokines. Recently, active research has been conducted on methods to shorten the time required for macrophage differentiation, proliferation, and activation without inducing hypersensitive reactions or anaphylaxis in the human body.

[0006] Against this backdrop, the present invention was completed by developing a technique for inducing polarization toward M2 macrophages using a porphyrin-based metal-organic framework.

[0007] One aspect provides a composition for inducing macrophage polarization, comprising a porphyrin-based metal-organic framework (MOF).

[0008] Another aspect provides a method of inducing polarization of cells in a subject, comprising administering to the subject a composition for inducing macrophage polarization.

[0009] Another aspect provides a method for inducing polarization of macrophages, comprising the step of treating isolated cells with the composition for inducing macrophage polarization.

[0010] One aspect is to provide a composition for inducing macrophage polarization, comprising a porphyrin-based metal-organic framework (MOF).

[0011] The term "metal-organic framework (MOF)" as used herein refers to a porous material in which metal clusters and organic linkers, or organic bridging ligands, are linked by coordination bonds to form a three-dimensional structure, and various MOFs can be created depending on the selection of metal ions and organic ligands. The MOF is characterized by porosity in which empty spaces exist within the structure, and the pore size, porosity, three-dimensional structure, surface area, etc. can be designed in various ways depending on the type and bonding method of the metal ions and organic ligands that make up the MOF. Due to this porosity, MOFs not only have a very large surface area but also have an open pore structure, so they can transport a large amount of molecules or solvents compared to other porous materials known in the art, and when used as a catalyst or gas storage medium, they have the advantage of having many active sites, which can maximize efficiency. In addition, the MOF does not easily deform at high temperatures and has a rigid skeleton, so it has excellent chemical and thermal stability.

[0023] The term "macrophage" in this specification refers to a representative immune cell that originates from bone marrow cells and plays a major role in innate immunity. Initially, it leaves the bone marrow through the bloodstream in the form of an immature monocyte. Monocytes recognize by-products or pathogens derived from infected cells, and their activity increases, differentiating into mature macrophages. Macrophages have an important function in maintaining tissue homeostasis by removing pathogens that have invaded from the outside, inducing adaptive immunity, and playing a very important role in the initial stage of inflammatory responses in the human body.

[0089] Next, for N2 adsorption isotherm and BET specific surface area-pore measurement, about 40 mg of completely dried sample was prepared and carefully placed in a glass sampler using a glass funnel, and all powder adhering around the glass tube except for the lower sample container was removed. After that, the upper filter cap was attached, and degas was performed by vacuum and heat treatment at 120 ℃ for 12 hours in a pretreatment device. The weight of the pretreated sample was measured using a microbalance, and the weight of the empty cell that was measured in advance was subtracted to calculate the weight of the intact sample. The glass sampler was attached to the N2 adsorption-desorption device and the measurement was performed (Company name: MICROTAAC / Model name: BELSORP MINI X).

[0090] As a result of the above measurement, it was confirmed that the metal-organic framework manufactured / synthesized in Example 1 was properly synthesized (MOF-525: FIGS. 3 to 7, MOF-545: FIGS. 10 to 14).

[0092] Example 3: Cytotoxicity Evaluation of Porphyrin-Based Metal-Organic Frameworks

[0093] To evaluate the cytotoxicity of porphyrin-based metal-organic frameworks, the following experiments were performed.

[0094] Specifically, to evaluate the cytotoxicity of the metal-organic framework manufactured / synthesized in Example 1, mouse fibroblasts (L929) were first seeded in a 96-well plate at 1X10 per well.5 Cells were added and cultured for 24 hours in a 37℃, 5% CO2 incubator. After 24 hours, the existing medium in each well was removed, and the metal-organic framework particles to be tested were suspended in the medium at a concentration of 50, 25, 10, or 1 ug / ml to make a test solution, and 100 ul was added to each well. The solution was cultured for 24 hours in a 37℃, 5% CO2 incubator, and the medium was removed. Next, the plate was washed three times with PBS to remove particles attached to the cell surface. Next, 10% EZ-cytox medium was added to each well and reacted in a 37℃ incubator for 1 hour, and the absorbance at 450 nm and 600 nm was measured to compare the cell viability with the control group.

[0095] As a result of the above cytotoxicity test, it was confirmed that MOF-525 and MOF-545 did not exhibit cytotoxicity at any concentration (Figs. 15 and 16).

[0096]

[0097] Example 4: Evaluation of the ability of porphyrin-based metal-organic frameworks to induce macrophage polarization.

[0098] To evaluate the ability of porphyrin-based metal-organic frameworks to induce macrophage polarization, the following experiments were performed.

[0099] Specifically, in order to evaluate the macrophage polarization induction ability of MOF-525 and MOF-545, which are metal-organic frameworks manufactured / synthesized in Example 1, first, mouse femurs and pelvic bones were separated, the epiphyseal portion was cut, and PBS was poured into the medullary cavity to collect bone marrow cells, thereby obtaining undifferentiated bone marrow-derived macrophages. ACK buffer was used to remove red blood cells from the collected bone marrow cells. Next, 10 mL of DMEM medium and 1 mL of L929 culture supernatant were added to a cell culture dish, and the bone marrow cells obtained above were cultured for 6 days, and on the third day of culture, 10 mL of DMEM medium was added. Through the culture, the differentiated macrophages were cultured at 10 5 The cells were seeded into 96-well plates at a concentration of 10 cells / well and cultured for 24 hours. Test samples (50 or 100 ug / mL for each sample) were added to the cultured cells and incubated for 24 hours. Afterwards, unpolarized macrophages (M0) and M2 polarized macrophages were quantitatively analyzed using a flow cytometer and fluorescent antibodies. For the quantitative analysis of the M2 polarized macrophages, the number of cells with CD11b+, CD45+, and Arginase 1+ phenotypes was counted.

[0100] As a result of the evaluation of the ability to induce macrophage polarization, M2 polarized macrophages were significantly confirmed for MOF-525 and MOF-545 synthesized / manufactured in Example 1 (Fig. 17). Therefore, it can be seen that MOF-525 and MOF-545 can effectively induce polarization toward M2 macrophages, and based on this, it can be seen that porphyrin-based metal-organic frameworks can effectively induce polarization toward M2 macrophages.
