thymosin beta 15 Tβ15 Th22 cells hair regeneration hair follicle cell proliferation IL-22BP inhibitor adenovirus lentivirus

Studysummary This study identified Th22 cells as key effectors in hair regeneration driven by thymosin beta 15, suggesting they could be potential targets for hair regrowth therapies. Our plain-language summary of this paper — not a Tressless recommendation.

The study demonstrates that thymosin β15 (Tβ15) significantly promotes hair regeneration in mice by increasing the number and activity of Th22 cells around hair follicles. Overexpression of Tβ15 enhances hair follicle cell proliferation and maturation, while blocking Th22 activity or knocking down Tβ15 inhibits hair growth. The findings suggest that Tβ15 and Th22 cells are crucial for hair regeneration and could be potential drug targets for treating hair loss.
