The effect of therapy on TRM in psoriatic lesions

Abstract

The decreased expression of TRM markers occurring predominantly in the lesional dermis and not in the epidermis over 12 weeks of observation may be due to the poorer penetration of systemic drugs to the epidermis, or the process of psoriatic lesion regression in the epidermis is secondary to the reduction of inflammation in the skin, or TRM in the epidermis may be more resistant to therapy.
