Insights into the context-dependent immunological roles of the CXCL12–CXCR4 axis in alopecia
The chemokine CXCL12 and its receptor CXCR4 play context-dependent roles in hair follicle biology. While recent findings suggest that regulatory T cells (Tregs) utilize the CXCL12–CXCR4 axis to modestly promote hair follicle regeneration under homeosta…
