NGF activates TrkA on sensory nerves, upregulating the expression of pronociceptive molecules, such as capsaicin receptor (TRPV1), BDNF, and neuropeptides (substance P and CGRP), in sensory ...
This is done to evoke neurotrophic or pro-apoptotic signaling. NGF binds to TrkA; BDNF and neurotrophin 4 bind to TrkB; neurotrophin 3 binds to TrkC. BDNF, NGF, and all the receptors are known as ...
