Popis: Imiquimod (IMQ) induced human-like psoriasis in mice has been shown to be effective in testing and development of novel treatments. The IMQ psoriasis model has become widely used animal model, however, it is not completely characterized in different rat strains. We aimed to evaluate IMQ and betamethasone treatment for induction and reversal of psoriatic lesions on macroscopic, histological, genetic as well as cytokines and chemokines activation levels. Wistar rats were treated topically with IMQ. Adopted Psoriasis Area Severity Index (PASI) was calculated at the baseline, after the IMQ-symptoms induction and after betamethasone-symptoms reversal. Systematic effects were studied on cytokines and chemokines levels in plasma. Skin biopsy was taken to assess histological symptoms and selected inflammatory cytokines and receptors genes expression levels. Reversal of skin lesions, after betamethasone treatment, was significant (p = 0.03). Histological differences between untreated and IMQ-treated skin were significant for some markers (p
