p75 Neurotrophin receptor

The p75 neurotrophin receptor is a protein found on the surface of nerve cells that helps regulate their growth, survival, and death. It plays a crucial role in the nervous system by responding to certain growth factors called neurotrophins. Depending on the context and the presence of other signals, p75 can either promote nerve cell survival or trigger cell death, helping to shape and maintain healthy neural networks. This receptor is important for brain development, repair after injury, and maintaining neural balance.
