IL22 and psoriasis: In this study, we investigate the ability of Luteolin-7-glucoside (LUT-7G) flavone in regulating proliferative responses, as well as differentiation in interleukin 22 (IL-22)-treated cultured human keratinocytes and in the imiquimod (IMQ)-induced (psoriasiform) model of psoriasis32 and show that this compound has important effects on these processes and could be a potential new drug for psoriasis.
