Definitions
- the present invention relates to a composition for preventing or treating psoriasis containing a monoacetyldiacylglycerol compound, and more particularly, to effectively prevent and treat psoriasis, and to use a safe monoacetyldiacylglycerol compound without any side effects. It relates to a composition for preventing or treating psoriasis containing.
- Th17 cells T helper
- IL-17 T helper
- Psoriasis is a common skin inflammatory disease that is estimated to affect about 2% of the world's population.
- Psoriasis is a chronic inflammatory skin disease characterized by an increase in hyperproliferative keratinocytes and half scales, an immune-mediated autoimmune skin disease induced by chronic activation of inflammatory cell infiltration in the skin and dysregulation of epidermal keratinocytes.
- Psoriasis develops in the most irritated areas, such as elbows, knees, hips, and scalp, characterized by erythematous skin lesions covered with a clear, silvery-white scale.
- psoriasis is as follows. First, immune cells are activated by pathogens, and activated immune cells express STAT3, IL-23, and the like, and keratinocytes are activated through these factors. Activated keratinocytes express chemokine (chemokine) CXCL1, CXCL2, etc., through which psoriasis develops through the process of inducing the activation and mobilization of neutrophils.
- the IL-23 mainly plays an important role in activating Th17 cells, inducing differentiation and maintaining Th17 cells. STAT3 also activates Th17 cells.
- STAT an autoimmune disease-related transcription factor
- STAT3 is induced through IL-6, IL-10 stimulation (Frucht DM, et al., J Immunol 2000: 4659-64).
- STAT3 is known to be involved in cell growth and proliferation and, when activated, to move into the nucleus and induce the expression of proteins involved in the growth and proliferation of various cells. It also activates Th17 cells, a novel lineage of CD4 + T cells.
- STAT3 directly affects the differentiation and signaling of Th17 cells, and regulates RORrt, a specific transcription factor of Th17 cells (Onai N, et al., Immunity 2008: 490-492).
- TGF ⁇ has been known to inhibit the proliferation of keratinocytes in psoriasis, but recently TGF ⁇ 1 has been associated with skin inflammation similar to psoriasis, with TGF ⁇ 1 being angiogenesis and chemotaxis of inflammatory cells. It is believed to play an important role in the developmental mechanism of psoriasis by participating in the differentiation of Th17 cells.
- Th17 cells secrete IL-17, IL-17F, IL-21, IL-22.
- Th17 cells infiltrated into peripheral tissues act on macrophages, dendritic cells, fibroblasts, vascular endothelial cells, osteoclasts, etc., and various inflammatory cytokines (IL-1, TNF, IL-8, IL-6, etc.), chemokines, etc.
- Secretion causes tissue damage.
- secretion of IL-17 and IL-22 activates keratinocytes, and activated keratinocytes produce many inflammatory cytokine / chemokine precursors.
- Th17 cells have been found to be the major pathological cells that mediate inflammatory diseases, and Th17 cells and Th-17-mediated cytokines such as IL-17A, IL-22 and IL-23 have been reported to induce psoriasis triggers. Th17 cells can quickly initiate an inflammatory response dominated by neutrophils (Miossec, et al. 2009, NEJM; 361: 888-98).
- IL-17 is secreted from Th17 cells and consists of IL-17A, IL-17B, IL-17C, IL-17D, IL-17E (IL-25) and IL-17F, all of which have similar protein structures .
- IL-17 is an inflammatory cytokine that activates NF- K B and MAP kinases in immune cells and promotes the release of IL-6, PTGS2 / COX-2 and nitric oxide (Rouvier, et al., J. Immunol., vol. 150, no.
- IL-17 similar to IFN- ⁇ , produces chemokines in various tissues to recruit monocytes and neutrophils to sites of inflammation Is a cytokine that acts as a potent mediator in delayed-type responses.
- the IL-17 family functions as a proinflammatory cytokine in response to invasion of the immune system by extracellular pathogens and leads to the destruction of the cell matrix of the pathogen (Miossec P, et al. 2009, N. Engl. J. Med. 361: 888-98). Chemotaxis by chemokines with increased production by IL-17 leads to neutrophil recruitment and finally to excessive inflammatory dermatitis.
- Topical treatments are therapies including steroids, coal tar, anthraline, vitamin D3 and analogs thereof, retinoids and sunburn, and the like, which have the side effects of skin thinning, stretch marks, burns, irritation and photosensitivity. Steroids can also induce resistance, which affects subsequent steroid treatment.
- Phototherapy involves the administration of soralene with ultraviolet B or ultraviolet A, with the disadvantage that the skin ages quickly and the incidence of skin cancer is increased.
- the oral administration for the most severe psoriasis is the administration of immunomodulators such as cyclosporin. However, careful observation is necessary because it can cause nephrotoxicity or hypertension following prolonged use.

- FIG. 1 is a view showing an example of a mechanism for preventing psoriasis using the PLAG of the present invention.
- Th17 cells are stimulated with IL-6, IL-23, IL-21, and TGF- ⁇ , and the stimulated Th17 cells are IL-17, IL-17F, IL-21, IL-22.
- TNF Expressed IL-17 and IL-17F stimulate epithelial cells, induce the expression of chemokines of IL-6 and CXCL1, CXCL8, and expressed IL-6 in turn stimulates Th17 cells, giving positive feedback action, Neutrophils are recruited due to chemokines expressed from the activated epithelial cells.
- Administration of the compositions of the present invention to different mechanisms can inhibit the activity of IL-6 and IL-17 to block the migration of neutrophils from the blood to the skin, thereby preventing psoriasis.
- mice Prepared prior to in vivo or ex vivo treatment. Statistical analysis was also performed using a paired t- test. IMQ-treated mice show inflammation similar to psoriasis such as keratinization, increased epidermal thickness, and scaly shape.
- mice were randomly divided into three groups: control group, psoriasis induction group and PLAG group.
- the IMQ used Aldara cream (3M Health Care Limited, UK) containing 5% IMQ.
- mice, and the like were depilated using hair removal cream.
- the control group was treated with petrolatum (Unilever, UK) and PBS
- the psoriasis group was treated with Aldara cream and PBS
- the PLAG group was treated with Aldara cream and PLAG. It was.
- Vaseline and Aldara cream were applied to the back of mice at 40 mg / day, respectively, and PBS and PLAG were orally administered at 250 mg / kg / day.
- mice were sacrificed.
- psoriasis was induced using IMQ cream (Aldara cream) as in Example 1.
- IMQ cream Aldara cream
- FIG. 3 (A) photographs of Day 5 and the like of mice treated as in Example 1 were taken.
- the back skin was separated to measure the thickness of the back skin, and the thickness of the separated back skin was measured using a caliper.
- the measured thickness of the back skin is shown in the graph of FIG. 3 (B).
- the psoriasis induction group was confirmed that psoriasis was induced on the back and severe keratosis occurred.
- the PLAG group compared to the psoriasis induction group, it was confirmed that keratosis was significantly relieved.
- the graph (B) of FIG. 3 while the back skin thickness of the psoriasis induction group was considerably thicker than that of the control group, the thickness of the back skin of the PLAG group was significantly reduced.
- PLAG inhibits the progression of psoriasis and may have a therapeutic effect on inflammatory skin disease.
- the size and weight of the spleen tends to increase, and in general, it is used as an indicator to measure the degree of toxicity or inflammatory response in drug experiments.
- Increasing the spleen size and weight of a mouse can mean an increase in inflammation in the mouse. Accordingly, the spleens of the mice of Example 1 were separated, and the size and weight of the spleens were compared with each other.
- the size of the spleen separated from the mice of Example 1 was measured using a ruler, the weight was measured using a balance.
- the measurement result was shown as (A) and (B) of FIG.
- the size of the spleen appeared to increase in both groups treated with IMQ compared to the control group, as shown in the graph of Figure 4 (B), the spleen of the PLAG group
- the weight maintained the spleen weight as the control. From this result, it was confirmed that PLAG may have an effect of inhibiting the inflammatory response.
- the thickness of the back skin of the mice of Example 1 was dyed by the following H & E (Hematoxylin and Eosin) staining method and histologically observed and evaluated under an optical microscope (Olympus, Tokyo, Japan), and the image was taken at X100 magnification. 5.
- H & E staining method is as follows.
- mice The dorsal skin tissue of mice was fixed in 10% buffered formalin solution for 24 hours, paraffin embedded and cut into 4um thick sections. After removing paraffin and rehydrating, the sections are stained with Hematoxylin and Eosin.
- Figure 5 is a photograph showing the extent of epidermal thickness due to the formation of scales of the back skin and proliferation of keratinocytes of each group of mice of Example 1.
- the dorsal skin of the control group has a thin epidermis and a structure in which hair follicle cells (Hair Follicle) are constantly positioned, and the outer skin of the epidermis (Skin Keratinocytes, Scales) is also thin.
- the psoriasis induction group has a thicker epidermal thickness and epidermal hyperplasia of the epidermal layer.
- Hair follicle cells are also reduced, the keratin is very severe, the stratum corneum is thickened, and inflammatory cells, or neutrophils, are identified between the stratum corneum.
- the PLAG group compared with the psoriasis induction group, the thickness of the stratum corneum and epidermal layer is significantly reduced, it can be confirmed that the hair follicles exist as a control, neutrophils are not visible. Therefore, it can be seen that administration of PLAG inhibits psoriasis by IMQ and regulates inflammation.
- Neutrophil staining via immunohistochemical staining was performed as follows. Sections prepared in Example 4 were prepared overnight at 4 ° C. with primary rat anti-mouse neutrophil (NIMP-R14, Thermo Fisher Scientific Inc.) (1: 1000) antibody Incubated. After washing with Tris buffered saline (TBS), slides were prepared with horseradish peroxidase-conjugated goat-anti-rat IgG (Santa Cruz Bioechnology) secondary antibody diluted 1: 250. Incubated together at room temperature for 15 minutes.
- Tissue sections were immersed in 3-amino-9-ethylcarbazole (AEC, Dako, Denmark) as substrate, and samples were counterstained with 10% Mayer's hematoxylin, fixed in dehydration and crystal mounts. .
- the same irrelevant goat IgG and antibody dilutions of the isotype served as negative controls. Observed under an optical microscope (Olympus, Tokyo, Japan), taken at X40 and X200 magnification, and shown in FIG. 6.
- PLAG plays a protective role in inhibiting the inflammatory response of psoriasis by inhibiting the migration of neutrophils in the skin.
- Immunohistochemical staining the expression level of IL-17 in the back skin of the mice of Example 1 was confirmed.
- Immunohistochemical staining method was performed in the same manner as in Example 5 except for using an anti-mouse IL-17 antibody instead of using an NIMP-R14 antibody as the primary antibody. Observed under an optical microscope (Olympus, Tokyo, Japan), taken at X100 and X200 magnification, and shown in FIG. 7.
- IMQ-treated dorsal skin shows increased expression of IL-17 locally in blood vessels by immunohistochemical staining.
- Mice in the PLAG group show significant blockade of expression of IL-17 in the skin vessels and are similar to controls so that EC-18 modulates the expression of IL-17 associated with skin inflammation of psoriasis and thus into IMQ. It was confirmed that plays a role in inhibiting the induced psoriasis.
- FIG. 8 is a graph showing the increased expression and secretion of IL-17 and IL-6 proteins in serum of IMQ-induced psoriasis mice when the composition of the present invention was administered. As shown in FIG. 8, the expression levels of IL-17 and IL-6 present in serum were increased two to three times compared to the control group in the mouse group induced by psoriasis by IMQ. It showed similar expression amount and no change.
