Nerve growth factor beta (NGFβ)

Nerve growth factor beta (NGFβ) is a neurotrophin essential for the growth, maintenance, and survival of specific neuron populations, particularly sensory and sympathetic neurons. NGFβ functions by binding to two main receptors—NTRK1 (TrkA) and p75NTR—on neuronal and other cell surfaces, activating intracellular signaling pathways that support neuron growth, differentiation, survival, and pain perception. NGFβ also influences immune responses and pancreatic beta cell survival. Genetic mutations in NGFβ can lead to hereditary sensory and autonomic neuropathy type V, characterized by congenital insensitivity to pain. Therapeutic targeting of NGF, especially for pain conditions, has focused on monoclonal antibodies that neutralize NGF activity, though these treatments carry notable safety concerns including risks of joint damage and altered pain perception [1][2][6].

Antibody drugs targeting NGF (e.g., tanezumab) block NGF activity and prevent it from binding to its cell-surface receptors, thereby reducing pain signaling [1][2].
