Biological process

neurotrophin receptor signaling pathway

The series of molecular signals initiated by neurotrophin binding to its receptor on the surface of a target cell, and ending with the regulation of a downstream cellular process, e.g. transcription. Neurotrophins are a family of secreted growth factors that induce the survival, development, and function of neurons.

There are two classes of receptors for neurotrophins: p75 and the Trk family of tyrosine kinase receptors.
