Background: Tropomyosin receptor kinase B (TrkB), encoded by NTRK2, is a neurotrophic receptor (NTRs) in the brain and is highly enriched in the neocortex, hippocampus, striatum, and brainstem, and altered TrkB expression is implicated in CNS pathologies e.g. Parkinson’s disease. The tyrosine kinase receptor TrkB, is activated specifically by brain derived growth factor and neurotrophin 4 (BDNF and NT4). BDNF binding to TrkB triggers its dimerization and autophosphorylation, resulting in activation of the three major signaling pathways involving mitogen-activated protein kinase (MAPK), phosphatidylinositol 3-kinase (PI3K), and phospholipase C-g1 (PLC-γ1), mediating neural differentiation, survival, and neurogenesis. TrkA and TrkB are known to operate as proto-oncogenes contributing to cell migration and invasion as well as neovascularization in various types of cancer.
