    Glossaryp75 neurotrophin receptor (p75)

    protein on cell surfaces regulating survival and apoptosis

    The p75 neurotrophin receptor (p75NTR) is a protein found on the surface of certain cells, including neurons and hair follicle cells. It plays a crucial role in regulating cell survival, growth, and apoptosis (programmed cell death) by binding to neurotrophins, which are a family of proteins that promote the survival and function of neurons. This receptor is significant in both the development of the nervous system and in conditions like alopecia, where it can influence hair follicle health and regeneration.
