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 .
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.
Cytokines and chemokines regulate neurotrophins and other molecules critical to neurodevelopmental processes, and exposure to certain neuroimmune challenges early in life affects brain development. In adults, cytokines and chemokines affect synaptic plasticity and other ongoing neural processes, which may change in aging brains. Finally ...
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 ...
Neurotrophic factors also promote the initial growth and development of neurons in the central nervous system and peripheral nervous system, and they are capable of regrowing damaged neurons in test tubes and animal models. [1] [4] Some neurotrophic factors are also released by the target tissue in order to guide the growth of developing axons.

Tropomyosin receptor kinase B is the high affinity catalytic receptor for several "neurotrophins", which are small protein growth factors that induce the survival and differentiation of distinct cell populations. The neurotrophins that activate TrkB are: BDNF (Brain Derived Neurotrophic Factor), neurotrophin-4 (NT-4), and neurotrophin-3 (NT-3).
