Abstract

Dysfunctional autophagy is linked to various diseases, including psoriasis and atopic dermatitis. Recent evidence suggests that exposure of keratinocytes to TNF-α results in impaired autophagy and lysosomal function. The skin of patients with psoriasis and atopic dermatitis reveals a decreased expression of lysosomal cathepsins. Impaired autophagy is presumably involved in inflammation and disturbed keratinocyte differentiation, whereas stimulating autophagy might be a treatment option in inflammatory skin disease.
