A Surprising Link Between Immune System and Hair Growth

Summary: Regulatory T cells interact with skin cells using glucocorticoid hormones to generate new hair follicles and promote hair growth. The findings could have positive implications for the development of new therapies to treat alopecia and other hair loss disorders. Source: Salk Institute Salk scientists have uncovered an unexpected molecular target of a common treatment for alopecia, a condition in which a person’s immune system attacks their own hair follicles, causing hair loss. The findings, published in Nature Immunology on June 23, 2022, describe how immune cells called regulatory T cells interact with skin cells using a hormone as a messenger to generate new hair follicles and hair growth. “For the longest time, regulatory T cells have been studied for how they decrease excessive immune reactions in autoimmune diseases,” says …
