In the mature nervous system, they promote neuronal survival, induce synaptic plasticity, and modulate the formation of long-term memories. [2] 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 ...
According to the United States National Library of Medicine's medical subject headings, the term neurotrophin may be used as a synonym for neurotrophic factor, [5] but the term neurotrophin is more generally reserved for four structurally related factors: nerve growth factor (NGF), brain-derived neurotrophic factor (BDNF), neurotrophin-3 (NT-3), and neurotrophin-4 (NT-4). [6]
The Trk proteins act as receptors for NGF and related factors. Trk is a receptor tyrosine kinase. Trk dimerization and phosphorylation leads to activation of various intracellular signaling pathways including the MAP kinase, Akt, and PKC pathways. CNTF: Ciliary neurotrophic factor is another protein that acts as a survival factor for motor neurons.
The development of the nervous system in humans, or neural development, or neurodevelopment involves the studies of embryology, developmental biology, and neuroscience.These describe the cellular and molecular mechanisms by which the complex nervous system forms in humans, develops during prenatal development, and continues to develop postnatally.
Neurotrophic factors are biomolecules – nearly all of which are peptides or small proteins – that support the growth, survival, and differentiation of both developing and mature neurons. [2] [3] [4] Examples of notable neurotrophic factors include: Insulin-like growth factor-1 (IGF-1) Glial cell line-derived neurotrophic factor (GDNF)

The term was first coined (from the Latin ramus = branch and the Greek genesis = creation) in an article about kidney development by Davies and Davey (Pediatr Nephrol. 1999 Aug;13(6):535-41). In the article, Davies and Davy describe the existence of "ramogens" in the kidney as glial cell line-derived neurotrophic factors, neurturin and ...
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.
