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]
Recent research has suggested a number of roles for the LNGFR, including in development of the eyes and sensory neurons, [20] [21] and in repair of muscle and nerve damage in adults. [ 22 ] [ 23 ] [ 24 ] Two distinct subpopulations of Olfactory ensheathing glia have been identified [ 25 ] with high or low cell surface expression of low-affinity ...
Neurotrophins are a family of proteins that induce the survival, [1] development, and function [2] of neurons. They belong to a class of growth factors, secreted proteins that can signal particular cells to survive, differentiate, or grow. [3] Growth factors such as neurotrophins that promote the survival of neurons are known as neurotrophic ...
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 .

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]
Neurotrophin ligands of Trk receptors are processed ligands, [3] meaning that they are synthesized in immature forms and then transformed by protease cleavage. Immature neurotrophins are specific only to one common p75NTR receptor. However, protease cleavage generates neurotrophins that have higher affinity to their corresponding Trk receptors.
p75 is a low affinity neurotrophin receptor, to which all neurotrophins bind. It is a member of the tumour necrosis super family. In some contexts, the phrase "x" only applies to this receptor. [1] The Trk family include TrkA, TrkB, and TrkC, and will only bind with specific neurotrophins, but with a much higher affinity. The Trks mediate the ...
