Neurotrophin-3, or NT-3, is a neurotrophic factor, in the NGF-family of neurotrophins. It is a protein growth factor that has activity on certain neurons of the peripheral and central nervous system ; it helps to support the survival and differentiation of existing neurons, and encourages the growth and differentiation of new neurons and synapses .
Most neurotrophic factors belong to one of three families: (1) neurotrophins, (2) glial cell-line derived neurotrophic factor family ligands (GFLs), and (3) neuropoietic cytokines. [4] Each family has its own distinct cell signaling mechanisms, although the cellular responses elicited often do overlap. [4]
Neurotrophin-4 (NT-4), [5] also known as neurotrophin-5 (NT-5), is a protein that in humans is encoded by the NTF4 gene. [6] It is a neurotrophic factor that signals predominantly through the TrkB receptor tyrosine kinase. [7] [8] NT-4 was first discovered and isolated from xenopus and viper in the year 1991 by Finn Hallbook et.al [9]
Adult neurogenesis is the process in which neurons are generated from neural stem cells in the adult. This process differs from prenatal neurogenesis . In most mammals, new neurons are born throughout adulthood in two regions of the brain: [ 3 ]
Brain-derived neurotrophic factor (BDNF), or abrineurin, [5] is a protein [6] that, in humans, is encoded by the BDNF gene. [7] [8] BDNF is a member of the neurotrophin family of growth factors, which are related to the canonical nerve growth factor (NGF), a family which also includes NT-3 and NT-4/NT-5.

The p75 neurotrophin receptor (p75NTR) was first identified in 1973 as the low-affinity nerve growth factor receptor (LNGFR) [5] [6] before discovery that p75NTR bound other neurotrophins equally well as nerve growth factor. [7] [8] p75NTR is a neurotrophic factor receptor.
Neurotrophin-3 is a protein that in humans is encoded by the NTF3 gene. [ 5 ] [ 6 ] The protein encoded by this gene, NT-3, is a neurotrophic factor in the NGF (Nerve Growth Factor) family of neurotrophins .
