This study found that keratin 17 and TNFα play interdependent roles in regulating hair follicle cycling, with TNFα required for the anagen–catagen transition and its ablation partially rescuing hair cycling defects in K17-null mice.

This study shows that macrophage-induced TNF signaling can activate hair follicle stem cells and promote new hair follicle formation after wounding by regulating AKT/β-catenin pathways.
