The hair follicle regulates hair growth via a complex interaction between hormones, neuropeptides, and immune cells. [1] This complex interaction induces the hair follicle ...
Dermal macrophages are usually present in the dermis and around hair follicles. Dermal macrophages are macrophages in the skin that facilitate skin homeostasis by mediating wound repair, hair growth, and salt balance. [1] Their functional role in these processes is the mediator of inflammation. They can acquire an M1 or M2 phenotype to promote ...
