Mechanisms of autophagy and their implications in dermatological disorders

The document reviews the role of autophagy, a cellular degradation process, in various dermatological disorders such as vitiligo, atopic dermatitis, alopecia areata, and systemic sclerosis. Autophagy influences oxidative stress responses, inflammation, and immune regulation in these conditions. For example, dysregulated autophagy increases melanocyte sensitivity to oxidative stress in vitiligo, while enhancing autophagy can alleviate symptoms in atopic dermatitis and promote hair growth in alopecia areata. The review suggests that targeting autophagy pathways, including the use of Janus kinase inhibitors and other small molecules, could be effective therapeutic strategies for managing these skin disorders.
