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.
Rs6265, also called Val66Met or G196A, is a gene variation, a single nucleotide polymorphism (SNP) in the BDNF gene that codes for brain-derived neurotrophic factor. Well over a hundred research studies have examined the polymorphism.
[1] [4] Some neurotrophic factors are also released by the target tissue in order to guide the growth of developing axons. 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]
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).

Tropomyosin receptor kinase B (TrkB), [5] [6] [7] also known as tyrosine receptor kinase B, or BDNF/NT-3 growth factors receptor or neurotrophic tyrosine kinase, receptor, type 2 is a protein that in humans is encoded by the NTRK2 gene. [8] TrkB is a receptor for brain-derived neurotrophic factor (BDNF).

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)
This hints that the G2/M checkpoint aids in the survival of tetraploid neurons. This is supported by experiments in which the G2/M checkpoint is removed through addition of brain-derived neurotrophic factor (BDNF) blockers in tetraploid cells that resulted in cell death. BDNF prevents the G2/M transition through its receptor TrkB and their ...
