TrkA agonists are compounds that specifically activate the TrkA receptor, a high-affinity receptor for nerve growth factor (NGF). The TrkA receptor is part of the tropomyosin receptor kinase (Trk) family and plays a crucial role in the development and function of the nervous system. Activation of TrkA by these agonists can initiate a cascade of intracellular signaling pathways that promote cell survival, differentiation, and growth.
