ガスダーミンEを標的とする抗体は、乾癬の治療選択肢となる可能性：マウスモデルを用いたパイロットスタディ

Psoriasis is a frequent and complex dermatosis of uncertain origin. A few years ago, a family of gasdermin proteins was implicated in psoriasis pathogenesis. Although the number of therapeutic options for psoriasis is growing, considering the burden of the disease, treatment personalization, and the possibility of side effects or loss of the drug's efficacy, it is important to seek new therapeutic targets.

The aim of this study was to assess the efficacy of antibodies against gasdermin E (GSDME) in the treatment of psoriatic lesions.

The study involved 30 male BALB/c mice, 8 weeks old. 5% imiquimod cream was applied topically on the skin to induce psoriatic lesions. The next day after the psoriatic lesions appeared, the antibodies were administered. Mice from the study group received the rabbit polyclonal anti-GSDME antibody intravenously or intraperitoneally. The control group was administered sterile 0.9% saline solution.

The injection of anti-GSDME antibodies to mice with imiquimod-induced psoriasis resulted in the resolution of skin lesions, whereas the injection of saline to the control group did not result in significant changes.

Antibodies targeting GSDME seem to be promising therapeutic agents in psoriasis; however, their utility has to be confirmed in future studies.
