Meanwhile, STM2457 ameliorated the IMQ‐induced psoriasis‐like phenotype, as evidenced by reduced PASI scores, alleviation of histopathological hallmarks including epidermal hyperplasia, hyperkeratosis, and parakeratosis, as well as downregulated expression of pro‐inflammatory mediators such as Il17a, Il17f, S100a8, and Tnfa (Figure S7, Supporting Information). The gene discussed is IL17A; the disease is Hyperkeratosis.
