The G-Protein Couple Receptor Kinase 2 (GRK2) Orchestrates Hair Follicle Homeostasis.

A preprint abstract from biorxiv.org discusses the role of the G-Protein Couple Receptor Kinase 2 (GRK2) in maintaining hair follicle homeostasis. The study used a mouse model to show that the ablation of GRK2 in keratinocytes led to abnormal cyst-like structures in the hair germ region, resulting in hair loss. These cysts displaced the dermal papilla and caused irreversible changes in hair follicle stem cell architecture. The findings suggest potential connections between dystrophic follicular cyst formation and immune-mediated alopecias. However, it is important to note that this preprint has not yet undergone peer review. [Extracted from the article]
