Abstract
Description
[Technical Field]
[0001] The present invention relates to a pharmaceutical composition for preventing or treating central nervous system diseases (neurological diseases) comprising umbilical cord blood or umbilical cord blood-derived cells that express or secrete PCNT as an active ingredient, a composition or kit for diagnosing neurological diseases comprising an agent for measuring the level of PCNT protein, a method for analyzing information necessary for diagnosing neurological diseases using PCNT protein, and a method for screening candidate substances for treating neurological diseases. [Background technology]
[0002] The cranial nervous system refers to the body's regulatory system, which is composed of the brain, spinal cord, cranial nerves, spinal nerves, and autonomic nervous system. Cranial nervous system disorders include cerebral palsy, brain injury, traumatic brain injury, ischemic brain injury, cerebral concussion, cerebral infarction, cerebral hemorrhage, Parkinson's disease, Alzheimer's disease, Huntington's disease, dementia, Lou Gehrig's disease, Huntington's disease, Pick's disease, Creutzfeldt-Jakob disease, amyotrophic lateral sclerosis, primary lateral sclerosis, degenerative ataxia, multiple sclerosis, nervous system dysfunction, memory loss, epilepsy, encephalitis, prion disease, and other neurological disorders. Brain injury refers to a condition in which abnormalities in the brain's nervous tissue, caused by various internal or external factors, result in behavioral or functional abnormalities. Brain injury can result from open head injury, closed head injury, deceleration injury, toxic exposure, oxygen deprivation, tumors, infections, and cerebrovascular diseases such as stroke.
[0003] Cerebral palsy is not a single disease, but a collective term for a group of symptoms with similar clinical characteristics. It refers to a group of clinical symptoms that show movement and posture disorders caused by non-progressive lesions or damage to the immature brain. Cerebral palsy is a disease that causes problems with muscle control and maintaining posture while walking due to damage to the brain during the developmental process. Brain damage occurs mainly before, during, or after birth, but can occur at any time during pregnancy and even in childhood.
[0004] Although the brain injury is non-progressive, the neuromotor disorder and musculoskeletal disorder change over time, so rehabilitation treatment that is most appropriate for the changed clinical condition must be provided through periodic examinations. Although other treatment methods are available, there is currently no revolutionary or fundamental treatment method that can be used through these methods.
[0005] It has been reported that stimulating the potential of brain plasticity may be a potential treatment for cerebral palsy, and it has shown positive effects in patients with brain injury. One method for stimulating the potential of brain plasticity is cell therapy.
[0006] Korean Patent Publication No. 14093336 (Patent Document 1) relates to the use of oligodendrocyte precursor cells as a cell therapy agent for central nervous system diseases, and discloses a composition for treating central nervous system diseases containing, as an active ingredient, oligodendrocyte precursor cells, which are stem cells transformed with an expression vector containing an Olig2 gene-encoding nucleic acid molecule.
[0007] On the other hand, direct transplantation of stem cells, including mesenchymal stem cells, can result in problems such as failure to differentiate and survive in vivo and difficulty in quantitative administration, making their use in cell therapy difficult. Therefore, there is a need to develop a cell therapy that does not induce rejection in vivo and has therapeutic effects on motor and cognitive development. [Prior art documents] [Patent documents]
[0008] [Patent Document 1] Korean Patent Registration No. 14093336 Summary of the Invention [Problem to be solved by the invention]

DETAILED DESCRIPTION OF THE INVENTION
[0018] The term "pericentrin (PCNT)" refers to a protein that binds calmodulin, is expressed in centrosomes, and forms the centrosome together with centrioles. PCNT protein is known to play an important role in cell division (Liu Q et al., Aug. 2010, Cell Research. 20 (8): 948-62), and abnormalities in this protein have been reported to cause mental disorders (Unal S et al., Feb. 2014, Pediatric Blood & Cancer. 61 (2): 302-5). It was confirmed that PCNT protein is expressed at higher levels in umbilical cord blood compared to plasma from normal individuals, but at lower levels in cerebral palsy patients compared to plasma from normal individuals. Furthermore, it was confirmed that PCNT protein is expressed at higher levels in cerebral palsy patients who underwent umbilical cord blood cell therapy compared to before treatment. These results suggest that PCNT protein can be used as a diagnostic marker for diagnosing cranial nervous system diseases such as cerebral palsy, and also that PCNT protein is involved in the prevention or treatment of cranial nervous system diseases. Therefore, umbilical cord blood or umbilical cord blood-derived cells with high PCNT protein expression may be used to prevent or treat cranial nervous system diseases.
[0019] The PCNT protein may be secreted from umbilical cord blood or umbilical cord blood-derived cells. The PCNT protein may be derived from a mammal, such as a human, monkey, or rodent. In one embodiment, the PCNT protein consists of the amino acid sequence of SEQ ID NO: 1 (GenBank Accession No. XP_005261181).
[0020] In one embodiment, the cranial nervous system disease is a cranial nervous system disease in which PCNT expression is reduced compared to normal. In another embodiment, the cranial nervous system disease includes any disease in which abnormalities or disorders occur in part or all of the components of the cranial nervous system, such as the brain, spinal cord, cranial nerves, spinal nerves, and autonomic nervous system. In another embodiment, the cranial nervous system disease is a brain injury disease. In another embodiment, the cranial nervous system disease is a nerve injury disease. In another embodiment, the cranial nervous system disease is selected from the group consisting of, but not limited to, cerebral palsy, brain injury, traumatic brain injury, ischemic brain injury, brain concussion, brain contusion, stroke, cerebral infarction, cerebral hemorrhage, Parkinson's disease, Alzheimer's disease, Huntington's disease, dementia, Lou Gehrig's disease, Huntington's disease, Pick's disease, Creutzfeldt-Jakob disease, amyotrophic lateral sclerosis, primary lateral sclerosis, degenerative ataxia, multiple sclerosis, nervous system dysfunction, memory loss, epilepsy, encephalitis, prion disease, and neurological diseases. In another embodiment, the cranial nervous system disease is cerebral palsy.
[0021] The term "cerebral palsy" refers to a disease in which non-progressive lesions or damage occur in the immature brain during or after birth due to various causative factors, resulting in clinically significant impairments of movement and posture.
[0022] The term "cord blood" refers to blood in the placenta or umbilical cord. Umbilical cord blood contains a large amount of hematopoietic stem cells that produce blood components such as white blood cells, red blood cells, and platelets, as well as various stem cells that produce cartilage, bone, fat, muscle, nerves, and other components. The term "stem cells" refers to primitive cells that are undifferentiated cells that can be transformed into any organ. Types of stem cells include embryonic stem cells and adult stem cells. Umbilical cord blood-derived stem cells include adult stem cells such as mesenchymal stem cells (MSCs). Umbilical cord blood can be obtained by separating it from the umbilical cord after birth. Umbilical cord blood can be used as a white blood cell concentrate, which excludes red blood cells and plasma. The cord blood leukocyte concentrate may contain a variety of cord blood-derived cells, including hematopoietic stem cells, monocytes, neutrophils, B-lymphocytes, T-lymphocytes, CD4 T cells, CD8 T cells, NK cells, peripheral blood mononuclear cells (PBMCs), platelets, lymph node cells, tonsil cells, bone marrow stromal cells, and bone marrow mesenchymal stem cells.
[0023] In one embodiment, the umbilical cord blood may be autologous or allogeneic. The allogeneic cord blood may be from a family member, such as a sibling or parent.
[0024] In one embodiment, the cord blood-derived cells are hematopoietic stem cells. In another embodiment, the cord blood-derived cells are cells that express or secrete PCNT. In another embodiment, the cord blood-derived cells are selected from the group consisting of, but not limited to, monocytes, B-lymphocytes, CD4 T cells, CD8 T cells, NK cells, peripheral blood mononuclear cells, platelets, and lymph nodes. In another embodiment, the cord blood-derived cells are peripheral blood mononuclear cells. In another embodiment, the cord blood-derived cells are genetically engineered to express or secrete, or to enhance, PCNT expression or secretion.
[0025] The pharmaceutical composition may further contain erythropoietin (EPO), a hormone that regulates red blood cell production in the bone marrow. When erythropoietin is administered in combination with cord blood or cord blood-derived cells, the therapeutic effects of cord blood are enhanced, and the motor and cognitive functions of patients can be further improved.
[0026] The term "treatment" refers to or includes the alleviation, slowing of progression, or prevention of a disease, disorder, or condition, or one or more symptoms thereof, and "active ingredient" or "pharmaceutically effective amount" means any amount of a composition utilized in the course of practicing the inventions provided herein sufficient to alleviate, slow the progression, or prevent a disease, disorder, or condition, or one or more symptoms thereof.
[0027] The terms "administer," "inject," and "implant" are used interchangeably and refer to the placement of a composition according to an embodiment into an individual by a method or route that results in at least partial localization of the composition according to an embodiment at a desired site. Administration may be by any suitable route that delivers cells, at least a portion of cellular components, or cell-derived secreted components of a composition according to an embodiment to a desired location within a living individual. The survival period of the cells after administration to an individual may be as short as a few hours, e.g., 24 hours to a few days, or as long as several years.
[0028] The pharmaceutical composition may further comprise a pharmaceutically acceptable carrier or diluent. Pharmaceutically acceptable carriers or diluents are also known in the art. The carrier or diluent may be lactose, dextrose, sucrose, sorbitol, mannitol, starch, acacia gum, calcium phosphate, alginate, gelatin, calcium silicate, microcrystalline cellulose, polyvinylpyrrolidone, cellulose, water (e.g., saline and sterile water), syrup, methylcellulose, methylhydroxybenzoate, propylhydroxybenzoate, talc, magnesium stearate, mineral oil, Ringer's solution, buffer, maltodextrin solution, glycerol, ethanol, dextran, albumin, or any combination thereof. The pharmaceutical composition may further comprise a lubricant, wetting agent, sweetener, flavoring agent, emulsifier, suspending agent, or preservative.
[0029] The pharmaceutical composition may be formulated using pharmaceutically acceptable carriers and / or excipients by methods known to those skilled in the art and prepared into a unit-dose form or in a multi-volume container. The dosage form may be a solution, suspension, syrup, or emulsion in an oil or aqueous solvent, or an extract, powder, powder, granule, tablet, or capsule, and may additionally contain a dispersant or stabilizer. The aqueous solvent may include physiological saline or PBS. According to one embodiment, the pharmaceutical composition may be formulated for oral or parenteral administration, preferably parenteral administration. For intramuscular, intraperitoneal, subcutaneous, and intravenous administration, a sterile solution of the active ingredient may generally be prepared, and a buffer may be added to appropriately adjust the pH of the solution. For intravenous administration, an isotonic agent may be added to impart isotonicity to the formulation.
[0030] In one embodiment, the pharmaceutical composition contains 1 x 10 nucleated cord blood-derived cells. 7 / kg or more, specifically, 2x10 7 / kg or more, 3x10 7 / kg or more, or 3x10 7 / kg or 10x107 / kg, e.g., 3x10 7 / kg or 5x10 7 / kg.
[0031] According to one embodiment, the effective daily dose of the pharmaceutical composition is about 0.01 to 200 ml, specifically about 0.01 to 150 ml, about 0.01 to 100 ml, about 0.1 to 150 ml, about 0.1 to 100 ml, about 1 to 100 ml, about 1 to 50 ml, about 5 to 50 ml, or about 10 to 40 ml, for example, 15 to 30 ml. If necessary, the umbilical cord blood can be appropriately concentrated before administration to reduce the total dose. However, the dose may vary depending on factors such as the formulation method, administration method, the patient's age, weight, sex, and condition, diet, administration time, administration route, excretion rate, and sensitivity, and those skilled in the art can appropriately adjust the dose taking these factors into consideration. The administration frequency can be once daily or two or more times per day within the range of clinically acceptable side effects. Administration can be at one or more sites, daily or at intervals of 2 to 5 days, with the total number of days of administration per treatment ranging from 1 to 30 days. If necessary, the same treatment can be repeated at an appropriate time. For non-human animals, the same dose per kg as for humans can be administered, or the dose can be converted based on, for example, the volume ratio (e.g., average) of organs (e.g., heart) between the target animal and humans. Possible administration routes include parenteral (e.g., subcutaneous, intramuscular, intra-arterial, intraperitoneal, intradural, or intravenous), topical (including transdermal), and injection or implantable device or substance insertion. In one embodiment, target animals for treatment include humans and other mammals, including humans, monkeys, mice, rats, rabbits, sheep, cattle, dogs, horses, and pigs.
[0032] Another aspect provides a composition or kit for diagnosing a central nervous system disease, which comprises an agent for measuring the level of PCNT protein or mRNA of its gene.
[0033] PCNT protein and cranial nervous system diseases are as described above.
[0034] In one example, it was confirmed that the expression level of PCNT protein is lower in plasma from cerebral palsy patients compared to that of normal individuals. Therefore, by measuring the expression and activity level of PCNT protein and comparing it with a sample from a normal individual, it is possible to diagnose the onset or progression of cranial nervous system diseases such as cerebral palsy. Therefore, PCNT protein is also a diagnostic marker for cranial nervous system diseases, such as cerebral palsy.
[0035] The term "diagnosis" means to confirm the existence or characteristics of a pathological condition. Accordingly, the term "diagnosis of a cranial nervous system disease" means to confirm whether or not a cranial nervous system disease has developed or the possibility of developing the disease, or to predict the risk of developing the disease.
[0036] The term "diagnosis marker" refers to a substance that can diagnose whether or not the above-mentioned cranial nervous system diseases have developed or the likelihood of developing the diseases.
[0037] The agent for measuring the protein may also be an antibody that specifically binds to the PCNT protein or a fragment thereof.
[0038] The agent for measuring the mRNA level of the gene may comprise a primer or probe that specifically binds to a nucleic acid encoding the PCNT protein or a fragment thereof.
[0039] Those skilled in the art can easily prepare antibodies that specifically bind to PCNT protein having a known amino acid sequence using known methods. Antibodies that specifically bind to PCNT protein or fragments thereof may include monoclonal antibodies, polyclonal antibodies, and recombinant antibodies, and may include not only complete forms having the full length of two heavy chains and two light chains, but also functional fragments such as Fab, F(ab'), F(ab')2, and Fv that retain at least the antigen-binding function.
[0040] Furthermore, those skilled in the art can design primers or probes that specifically amplify or recognize specific regions from the known PCNT gene sequence.
[0041] The term "primer" refers to a nucleic acid sequence of 7 to 50 strands with a short free 3' hydroxyl group that can base pair with a complementary template and serve as a starting point for template strand replication. While primers are usually synthesized, they can also be derived from naturally occurring nucleic acids. The primer sequence does not necessarily have to be exactly the same as that of the template; it only needs to be sufficiently complementary to hybridize with the template. The primer can initiate DNA synthesis in the presence of a polymerization reaction (i.e., DNA polymerase or reverse transcriptase) and four different nucleoside triphosphates in an appropriate buffer solution and temperature. The PCR conditions and the lengths of the sense and antisense primers can be varied based on knowledge in the art. Therefore, PCR amplification can be performed using sense and antisense primers of the nucleotide sequence of the PCNT gene to diagnose nervous system diseases.
[0042] The term "probe" refers to a nucleic acid fragment, such as RNA or DNA, as short as a few bases or as long as several hundred bases, capable of specifically binding to mRNA and capable of detecting the presence or absence of a specific mRNA. Such probes may be prepared in the form of oligonucleotide probes, single-stranded DNA probes, double-stranded DNA probes, RNA probes, etc. The selection of an appropriate probe and hybridization conditions may vary based on techniques known in the art. Therefore, hybridization can be performed using a probe complementary to the nucleotide sequence of the PCNT gene, and nervous system diseases can be diagnosed based on the degree of hybridization.
[0043] The primers or probes described above can be chemically synthesized using phosphoramidite solid support methods or other widely known methods. Such nucleic acid sequences can incorporate additional features that do not alter their basic properties. Examples of additional features that can be incorporated include, but are not limited to, methylation, capping, substitution of one or more nucleic acids with homologs, and variations between nucleic acids.
[0044] The kit may also be an RT-PCR kit, a microarray chip kit or a protein chip kit.
[0045] The kit may further include one or more other components suitable for the analytical method. When the analytical method is RT-PCR, the kit may further include necessary containers, reaction buffer, deoxynucleotides (dNTPs), PCR DNA polymerase, reverse transcriptase, etc. in addition to the primer set specific for PCNT protein. When the analytical method is ELISA, the kit may further include reagents for detecting the bound antibody, such as a secondary antibody, a chromophore, an enzyme, and its substrate.
[0046] Another aspect provides a method for analyzing information necessary for diagnosing a nervous system disease, comprising measuring the expression or activity level of PCNT protein or its gene in a sample isolated from an individual, and comparing the measured expression or activity level with the expression or activity level of PCNT protein measured in a control sample isolated from a normal individual.
[0047] PCNT protein and cranial nervous system diseases are as described above.
[0048] The method comprises measuring the expression or activity level of PCNT protein or its gene in a sample isolated from an individual.
[0049] The term "individual" refers to an individual for whom it is desired to determine whether or not a cranial nervous system disease has developed or to predict the risk of developing a disease. The individual is not limited to any species as long as it is an animal that can develop a cranial nervous system disease, and specifically includes mammals, such as humans (Homo sapiens).
[0050] The sample may include, but is not limited to, tissues isolated from an individual's body, cells, samples such as whole blood, serum, plasma, saliva, sputum, cerebrospinal fluid, urine, etc. In one embodiment, the sample is plasma.
[0051] The step of measuring the expression level of the PCNT protein or its gene can also be carried out by measuring the amount of mRNA of the PCNT gene or the PCNT protein.
[0052] The step of measuring the expression level of the PCNT protein, i.e., mRNA level, can also be performed by methods such as RT-PCR, competitive RT-PCR, real-time RT-PCR, RNase protection assay (RPA), Northern blotting, DNA chip, etc., but is not limited to these.
[0053] The step of measuring the activity level of the PCNT protein may also be performed by methods such as, but not limited to, Western blotting, magnetic bead-antibody immunoprecipitation, ELISA, mass spectrometry, radioimmunoassay, and immunoprecipitation.
[0054] The method includes a step of comparing the expression or activity level measured in the sample with the expression or activity level of PCNT protein measured in a control sample isolated from a normal individual. If the expression or activity level of PCNT protein in the sample is lower than that of the control sample isolated from a normal individual, it can be determined that the sample has a high probability of developing or progressing a cranial nervous system disease. Therefore, the method may include determining that a cranial nervous system disease is present if the measured expression or activity level is lower than that measured in the control sample.
[0055] Another aspect provides a method for screening candidate substances for treating cranial nervous system diseases, comprising the steps of contacting cells expressing PCNT protein with a test substance in vitro, measuring the expression level or activity of PCNT protein in the cells, and comparing the measured expression level or activity of PCNT protein with the expression level or activity measured in a control group, and selecting a test substance that increases the expression level or activity compared to the control group as a candidate substance for treating cranial nervous system diseases.
[0056] PCNT protein and cranial nervous system diseases are as described above.
[0057] We confirmed that PCNT protein expression levels were elevated in cerebral palsy patients who received umbilical cord blood cell therapy compared to before treatment, thereby confirming the positive effect on cerebral palsy. Therefore, substances that specifically increase the expression or activity of PCNT protein may be effective in treating cranial nervous system disorders such as cerebral palsy. Such effects indicate that PCNT protein or its gene is a target for the treatment of cranial nervous system disorders such as cerebral palsy.
[0058] The method comprises contacting a test substance in vitro with cells that express PCNT protein.
[0059] The cells expressing the PCNT protein include, but are not limited to, blood cells, brain cells, and the like.
[0060] The contact with the test substance may be by transfection, transformation or injection of the test substance.
[0061] The contact with the test substance is carried out in a medium capable of supporting the growth of the cells.
[0062] The method includes measuring the expression level or activity of PCNT protein in a cell.
[0063] The measurement can also be carried out using an antibody that specifically recognizes the PCNT protein or a fragment thereof, or a primer or probe that specifically recognizes a nucleic acid encoding the PCNT protein or a fragment thereof.
[0064] The expression level can also be measured by measuring the amount of PCNT gene mRNA or PCNT protein.
[0065] The amount of the mRNA can be measured by, but is not limited to, RT-PCR, competitive RT-PCR, real-time RT-PCR, RNase protection assay (RPA), Northern blotting, or DNA chip.
[0066] The amount of said protein can be measured by, but is not limited to, Western blotting, magnetic bead-antibody immunoprecipitation, ELISA, mass spectrometry radioimmunoassay or immunoprecipitation.
[0067] The method includes the step of comparing the measured expression level or activity of PCNT protein with the expression level or activity measured in a control group, and selecting a test substance that increases the expression level or activity compared to the control group as a candidate substance for treating a nervous system disease.
[0068] If the expression or activity level of PCNT protein is further increased after treatment with the test substance, the test substance is also selected as a substance that increases the expression or activity of PCNT protein and can be used to treat nervous system diseases.
[0069] The control group is cells under identical conditions except for the step of contacting with the test substance.
[0070] The present invention will be described in more detail below through examples. However, these examples are for illustrative purposes only and the scope of the present invention is not limited to these examples. [Example]
[0071] Example 1: Screening of proteins whose expression levels change after cord blood treatment Blood samples were collected from a child with cerebral palsy who underwent umbilical cord blood cell therapy before and after the treatment, and changes in specific proteins present in the plasma were observed. For this umbilical cord blood cell therapy, red blood cells and plasma were removed from the umbilical cord blood to prepare a leukocyte concentrate, which was then frozen and stored. The frozen leukocyte concentrate was thawed in a 37°C water bath before treatment and washed with a solution prepared by diluting equal amounts of 10% dextran 40 (100 g dextran 40 / 1 L water) and 5% albumin (50 g albumin / 1 L water). After washing, the leukocyte concentrate was diluted with 10 ml of a mixture of equal amounts of 10% dextran 40 and 5% albumin until a minimum total nucleated cell count of 3 x 10 7 The suspension was administered intravenously at a dose of 15 to 30 ml / kg.
[0072] 1-1. Preparation of plasma samples for screening Table 1 shows the diagnoses and cord blood treatments of cerebral palsy patients selected for plasma protein screening. Approximately 1-3 cc of blood from the cerebral palsy patients listed in Table 1 was collected in an EDTA tube and centrifuged at 2,000 rpm. The blood was separated into layers: red blood cells at the bottom, mononuclear cells in the middle, and plasma at the top. The plasma was then separated and stored in a -80°C ultra-low temperature freezer.
[0073] [Table 1]
[0074] 1-2. Screening of plasma proteins before and after cord blood cell therapy Two-dimensional gel electrophoresis (2DE) was used to confirm changes in specific proteins present in the plasma separated in Example 1-1. 2DE, image analysis, and qualitative analysis of the prepared samples were performed by the Yonsei Proteome Research Institute at Yonsei University.
[0075] Of the 10 cerebral palsy patients in Table 1, six showed improvement after receiving cord blood therapy, namely patients 4, 6, 7, 8, 9 and 10, and these were selected for the experiment.
[0076] Table 2 shows information about the experimental samples used to screen plasma proteins from six patients who showed improvement after receiving cord blood therapy. In Experiment 1, plasma from patients 4, 9, and 10 was mixed before cord blood therapy, and plasma from patient 4 was used as the sample for analysis 10 days after cord blood therapy. In Experiment 2, plasma from patients 6, 7, and 8 was mixed before cord blood therapy, and plasma from patient 6 was used as the sample for analysis 10 days after cord blood therapy.
[0077] [Table 2]
[0078] Figure 1A shows the results of two-dimensional gel electrophoresis to confirm changes in plasma proteins before cord blood treatment (Pre) and 10 days after treatment (Post+10 days), representing the results of Experiment 1 (analysis of samples from patients Nos. 4, 9, and 10). Figure 1B shows the results of two-dimensional gel electrophoresis to confirm changes in plasma proteins before cord blood treatment (Pre) and 10 days after treatment (Post+10 days), representing the results of Experiment 2 (analysis of samples from patients Nos. 6, 7, and 8). The horizontal axis represents pH, and the vertical axis represents protein size.
[0079] Table 3 shows the proteins that were found to increase more than three-fold in the plasma of patients who showed improvement after cord blood transfusion, based on the qualitative analysis of each protein using 2DE. The alpha-2-macroglobulin isoform is shown by two dots, suggesting that it is not completely filtered out of the sample when conducting experiments with proteins generally present in plasma. The protein with 626 dots is thought to be a fibrinogen-binding fragment, and this result also suggests that fibrinogen was not removed from the plasma. Therefore, pericentrin (PCNT) was confirmed to be the specific protein that increased in plasma after cord blood transfusion.

Preparation of plasma samples from children with cerebral palsy Table 4 shows the list of clinical cerebral palsy patients, the type of umbilical cord blood administered, and information regarding erythropoietin (EPO) infusion. Allogeneic umbilical cord blood was obtained from siblings or family members. Blood was separated from the 13 cerebral palsy patients listed in Table 4, and plasma was collected. The collected plasma was diluted 5:1 with phosphate-buffered saline (PBS) and quantified using the Bradford assay. Quantified protein was prepared by mixing 30 μg with sample buffer, boiling for 7 minutes, and then spinning down.
[0082] [Table 4]
[0083] 2-2. Confirmation of PCNT protein expression after cord blood treatment After the cord blood treatment, the expression of PCNT protein was confirmed by Western blot technique.
[0084] First, the plasma sample prepared in Example 2-1 was dispensed onto an 8% SDS-polyacrylamide gel in the order of before and after the cord blood treatment. The proteins dispensed onto the gel were transferred to a nitrocellulose (NC) membrane and reacted with PCNT antibody for 16 hours or more. The expression levels of PCNT before and after the cord blood treatment were confirmed by band analysis.
[0085] Figure 2 shows the results of Western blot analysis confirming PCNT expression in the plasma of 13 cerebral palsy patients before (Pre) and after (Post) cord blood treatment.
[0086] As shown in Figure 2, although there were differences in the dates before and after treatment for each sample, it was confirmed that the amount of PCNT generally increased after cord blood treatment, regardless of the type of cord blood.
[0087] Figure 3 is a graph showing the changes in PCNT expression levels before and after cord blood treatment, combining the results of all the patients shown in Figure 2.
[0088] As shown in Figure 3, it was confirmed that the expression level of PCNT increased 3 or 10 days after the cord blood treatment, and the results were significant.
[0089] Therefore, it was confirmed that when umbilical cord blood therapy was administered to cerebral palsy patients, the expression level of PCNT increased significantly.
[0090] Example 3: Confirmation of PCNT changes in animal models of cranial nervous system diseases 3-1. Creation of a rat model of induced cerebral palsy A hypoxic ischemia (HI) model, a cerebral palsy-induced rat model, was created using 7-day-old ICR mice. The right common carotid artery of 7-day-old ICR mice was ligated using 5-0 blue nylon and placed in a sealed special container maintained at 8% O2 and 92% N2. The mice were kept at 37°C and hypoxia-cerebral ischemia was induced for 1 hour. Six days after creating the HI model, the extent of brain tissue damage was visually inspected, and models with damage of 50% or more were excluded.
[0091] 3-2. Umbilical cord blood administration to a rat model of cerebral palsy The umbilical cord blood used was donated by Icord, the cord blood bank at Cha Hospital, for research purposes. The cord blood was centrifuged at 2,200 rpm to separate red blood cells, mononuclear cell layers, and plasma. The plasma was stored separately, and the mononuclear cell layer was isolated using Ficoll (Pharmacia Corp., USA). Specifically, the plasma-free red blood cells and mononuclear cell layer were diluted with PBS and placed on top of the Ficoll, followed by centrifugation at 2,200 rpm for 20 minutes. Due to the Ficoll principle, red blood cells, which are heavier than the Ficoll, sink to the bottom, leaving the mononuclear cell layer directly above the Ficoll. The isolated mononuclear cell layer was then transferred separately and spun down using 4x10 5 The cells / 10 g concentration were dissolved in 100 μl of saline. The prepared umbilical cord blood mononuclear cells were intraperitoneally administered randomly to rat models of cerebral palsy induced on day 7.
[0092] 3-3. Confirmation of changes in PCNT expression in brain tissue One week after administration of umbilical cord blood mononuclear cells, the cerebral palsy-induced rat model was killed by removing blood and then the brain tissue was removed. The removed brain tissue was homogenized using a lysis buffer and centrifuged to separate the protein. The altered expression level of PCNT was confirmed using Western blot analysis of 30 μg of the separated protein.
[0093] Figure 4 shows the results of measuring PCNT expression levels four times after administration of umbilical cord blood mononuclear cells (UCB) in a mouse model of cerebral palsy. A model administered with EPO was used as a comparison group.
[0094] As shown in Figure 4, we confirmed that the expression level of PCNT increased in a mouse model of cerebral palsy induced by administration of umbilical cord blood. We also confirmed that the expression level of PCNT increased in umbilical cord blood when compared with a model administered EPO as a comparison group.
[0095] Figure 5 is a graph showing the change in PCNT expression in Figure 4 converted into a percentage, based on the level when umbilical cord blood was not administered to a sham model in which cerebral palsy was not induced.
[0096] As shown in Figure 5, when umbilical cord blood was administered to the cerebral palsy-induced mouse model, the expression level of PCNT was even higher than when compared to the sham model, which is a normal mouse that did not receive umbilical cord blood.
[0097] Example 4: Verification of differences in PCNT levels present in umbilical cord blood, plasma of normal individuals, and plasma of children with cerebral palsy 4-1. Plasma separation in umbilical cord blood, normal human blood, and blood from cerebral palsy patients For the umbilical cord blood, research cord blood donated by iCord was centrifuged to separate the plasma, which was then frozen and stored in a -80°C ultra-low temperature freezer. For the normal blood, 3cc of blood from a woman and a man in their 20s and 30s was centrifuged to separate the plasma. For the cerebral palsy blood, blood from hospitalized cerebral palsy patients was centrifuged before cord blood treatment to separate the plasma. The two plasma samples were frozen and stored. Table 5 shows information on normal subjects and cerebral palsy patients, who were selected as comparison groups to confirm PCNT expression in umbilical cord blood.
[0098] [Table 5]
[0099] 4-2. Confirmation of PCNT Expression Levels in Umbilical Cord Blood, Normal Human Plasma, and Cerebral Palsy Patient Plasma The plasma stored in Example 4-1 was slowly thawed on ice and then diluted 5:1 with PBS. The diluted sample was quantified using Bradford reagent, and 30 μg of the sample was subjected to Western blot analysis.
[0100] Figure 6A shows the expression levels of PCNT in umbilical cord blood (UCB) plasma, normal plasma, and cerebral palsy patient plasma samples. Figure 6B shows the relative expression levels (%) of PCNT in umbilical cord blood (UCB) plasma, normal plasma, and cerebral palsy patient plasma samples, based on umbilical cord blood sample No. 1.
[0101] As shown in Figures 6A and 6B, the expression level of PCNT was significantly lower in the plasma of cerebral palsy patients, followed by that of normal individuals, and the highest level of PCNT was found in umbilical cord blood. Since there is no standard protein in plasma, the band stained with Ponceau was used as the standard, and the PCNT expression level was converted to a percentage, confirming that PCNT was most highly expressed in umbilical cord blood.
[0102] Example 5: Identification of cell types in umbilical cord blood that express PCNT Umbilical cord blood is blood found in the tissues of the umbilical cord and contains a large number of hematopoietic stem cells (HSCs). These stem cells are the main components of blood and have the potential to differentiate into monocytes, macrophages, and platelets produced in the bone marrow, as well as lymphoid cells such as T cells, B cells, and NK cells. Therefore, we identified the types of cells present in umbilical cord blood by determining whether they expressed PCNT. Information on PCNT-expressing cells was found on the GeneCards website (http: / / www.genecards.org / ).
[0103] Figure 7 shows the PCNT expression levels (Log 1) of the following components present in cord blood: serum, plasma, monocytes, neutrophils, B-lymphocytes, T-lymphocytes, CD4 T cells, CD8 T cells, NK cells, peripheral blood mononuclear cells (PBMCs), platelets, lymph nodes, tonsils, bone marrow stromal cells, and bone marrow mesenchymal stem cells. 10 , ppm).
[0104] As shown in Figure 7, PCNT was secreted by monocytes, B-lymphocytes, CD4 T cells, CD8 T cells, NK cells, peripheral blood mononuclear cells, platelets, and lymph nodes in the cells present in umbilical cord blood, and among these, peripheral blood mononuclear cells (PBMCs) showed the highest expression of PCNT.
[0105] Example 6: Confirmation of the therapeutic effect of umbilical cord blood on cranial nervous system diseases To confirm whether cord blood therapy is actually effective in treating neurological disorders in patients with neurological disorders, autologous cord blood therapy was performed on children with cerebral palsy.
[0106] In this cord blood cell therapy, cord blood was used after removing red blood cells and plasma to prepare a leukocyte concentrate, which was then frozen and stored. Before the procedure, the frozen leukocyte concentrate was thawed in a 37°C water bath and washed with a solution prepared by diluting equal amounts of 10% dextran 40 (100 g dextran 40 / 1 L water) and 5% albumin (50 g albumin / 1 L water). After washing, the leukocyte concentrate was diluted with 10 ml of a mixture of equal amounts of 10% dextran 40 and 5% albumin until a minimum total nucleated cell count of 3 x 10 was reached. 7The suspension was administered at a dose of between 15 ml and 30 ml / kg by intravenous injection.
[0107] Table 6 shows the gender, diagnosis, and functional evaluation results after cord blood treatment of 13 children with cerebral palsy who were selected to confirm the therapeutic effects of cord blood.
[0108] As shown in Table 6, it was confirmed that 13 cerebral palsy patients showed an improvement in overall function after cord blood treatment.
[0109] [Table 6]
[0110] In addition, 2 to 4 months after the cord blood treatment, patients 5, 11, and 13 were evaluated using the gross motor function classification system (GMFCS), Bayley Scales of Infant Development II motor (BSID II motor), and Bayley Scales of Infant Development II mental (BSID II mental).
[0111] FIG. 8 is a graph showing the GMFCS evaluation results (total GMFCS (%)) for cerebral palsy patients Nos. 5, 11, and 13 before (GMFCS_pre) and after (GMFCS_post) cord blood treatment.
[0112] FIG. 9 is a graph showing the results of the behavioral development domain assessment (BSID II motor) of the Bayley Scale of Infant Development for cerebral palsy patients Nos. 5, 11, and 13 before (BSID_Motor_pre) and after (BSID_Motor_post) cord blood treatment.
[0113] FIG. 10 is a graph showing the results of the mental development domain assessment (BSID II mental) of the Bayley Scale of Infant Development for cerebral palsy patients Nos. 5, 11, and 13 before (BSID_Mental_pre) and after (BSID_Mental_post) cord blood treatment.
[0114] As shown in Figures 8 to 10, the GMFCS, BSID II motor, and BSID II mental tests were conducted on cerebral palsy patients before and after cord blood therapy, and improvements were observed after cord blood therapy. [Industrial Applicability]
