Enhancing Tregs can protect against alopecia areata.

This article discusses the role of regulatory T cells in alopecia areata, where their deficiency in hair follicles may lead to impaired local immunity and suggests potential therapies like CAR-T reg cells and low-dose IL-2 to alleviate autoimmunity and promote hair regeneration in affected individuals.

Regulatory T cells help prevent autoimmunity and have potential for treating autoimmune diseases.

This review explored recent research on the immune mechanisms and potential therapeutic targets for alopecia areata, highlighting the roles of immune-related cells, autocrine and paracrine signaling, as well as factors like adipose-derived stem cells and gut microbiota in disease pathogenesis.

In this study, researchers demonstrated that CD4 T cells from skin-draining lymph nodes in mice with alopecia areata can transfer the disease to recipient mice, revealing a critical role for CD4 T cells in disease development and suggesting potential therapeutic targets.

This review discusses progress in targeted therapies for vitiligo, focusing on Janus kinase inhibitors and the potential of mesenchymal stem cells, but reports no new clinical results.
