【 摘 要 】

Objective: To investigate the therapeutical effect of topical application of FGF10 monoclonal antibody on the guinea pig model with psoriasis. Methods: Blank group, model group, hydrocortisone butyrate treatment group and high-dose (0.188mg/ml), middle-dose (0.094mg/ml) and low-dose (0.063mg/ml) FGF10 antibody group were set, respectively. After two-week treatment, pathological changes of psoriasis-like models were observed by HE staining, and the difference in VEGF and PCNA expression levels among different groups was observed by immunohistochemical staining. Results: All the test indicators of each treatment group were lower than those of the model group, and there was a significant difference (P<0.05). The inflammatory cell count of the high-dose FGF10 antibody group was not statistically different from those of the blank group (t=0.77, P=0.443), and the counts of the rest treatment groups were significantly higher than those of the blank group and the high-dose FGF10 antibody group (P<0.05). The epidermal thickness of each FGF10 antibody treatment group was significantly higher than that of hydrocortisone butyrate treatment group (P<0.05), while no statistical difference was found in the epidermal thickness among the FGF10 antibody treatment groups (P>0.05). FGF10 monoclonal antibodies can reduce the PCNA and VEGF expression in psoriasis-like model of guinea pig’s ear. Conclusion: FGF10 monoclonal antibodies can affect keratinocyte proliferation and division and can also significantly inhibit the inflammatory response in the psoriasis model. Meanwhile, FGF10 monoclonal antibodies can produce a therapeutic effect on psoriatic lesions by inhibiting the abnormal epidermis cell proliferation and neovascularization of the dermis in the psoriasis model.
