    Immunohistochemical staining of perfusion-fixed frozen mouse spinal cord sections with Anti-Neurotrophin 3 (NT-3) Antibody (#ANT-003), (1:300), followed by goat-anti-rabbit-AlexaFluor-488 (green). The same sections were stained with mouse anti-neurofilament 200 (NF) (red). Merge of the two images demonstrates the presence of NT-3 in gray matter which colocalizes with NF only in the soma of some neurons (arrow).

Scientific background

The neurotrophins ("neuro" meaning nerve and "trophe" meaning nutrient) are a family of soluble, basic growth factors which regulate neuronal development, maintenance, survival and death in the CNS and PNS.1 The structural hallmark of all neurotrophins is the characteristic arrangement of the disulfide bridges, known as the cysteine knot, which has been found in other growth factors such as PDGF.2 The rat and human forms of neurotrophin-3 (NT-3) are 96% homologous.  

NT-3 has been shown to strengthen synaptic connections to motoneurons in the neonatal rat,3 to serve as an anti-inflammatory factor, to suppress microglial activation,4 to play a critical role in regulating T helper 1/T helper 2 cell balance5 and to modify potassium currents in isolated inner hair cells from guinea pig cochlea.6 The biological effects of NT-3 are mediated by two receptors: TrkC, which is specific for NT-3, and p75NTR, which binds all the neurotrophins.7
