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 .
Polymicrogyria (PMG) is a condition that affects the development of the human brain by multiple small gyri creating excessive folding of the brain leading to an abnormally thick cortex. This abnormality can affect either one region of the brain or multiple regions.
Neurotrophin mimetics are small molecules or peptide like molecules that can modulate the action of the neurotrophin receptor. One of the main causes of neurodegeneration involves changes in the expression of neurotrophins (NTs) and/or their receptors (TrkA, TrkB, TrkC and p75NTR). Indeed, these imbalances or changes in their activity, lead to ...
Whereas neurotrophic factors within the neurotrophin family commonly have a protein tyrosine kinase receptor (Trk), Neurotrophin-3 (NT-3) has the unique receptor, TrkC. [8] In fact, the discovery of the different receptors helped differentiate scientists' understanding and classification of NT-3. [ 13 ]
TrkA is the high affinity catalytic receptor for the neurotrophin, Nerve Growth Factor, or "NGF".As a kinase, TrkA mediates the multiple effects of NGF, which include neuronal differentiation, neural proliferation, nociceptor response, and avoidance of programmed cell death.

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 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.
