WebMar 18, 2016 · Tropomyosin receptor kinase (Trk) family of receptors. The Trk receptor family comprises three transmembrane proteins referred to as Trk A, B and C (TrkA, TrkB and TrkC) receptors, and are encoded by the NTRK1, NTRK2 and NTRK3 genes, respectively. These receptor tyrosine kinases (TK) are expressed in human neuronal tissue, and play an … WebTrkB is the receptor for BDNF, and TrkB overexpression in RGCs with BDNF overexpression markedly enhances RGC survival, although not permanently [45].

WebApr 5, 2024 · As trkB.T1 is the sole isoform of trkB receptors expressed on astrocytes, we examined the function of trkB.T1-driven astrocytes in vitro and in vivo. Immunohistochemistry showed that trkB.T1 + cells were significantly upregulated 7 d after injury, with sustained elevation in white matter through 8 weeks. WebIn the present study, the expressions of BDNF and TrkB in the hippocampus were increased at 11 weeks after TBI induction. The expressions of BDNF and TrkB in neurons are linked with the phosphorylation of CREB (Griesbach et al., 2009; Wu et al., 2014). BDNF/TrkB signaling is critical for promoting neuronal survival following brain damage.

WebAug 18, 2024 · Activity-dependent insertion of the tropomyosin-related kinase B (TrkB) receptor into the plasma membrane can explain, in part, the preferential effect of brain-derived neurotrophic factor (BDNF) on active neurons and synapses; however, the underlying molecular mechanisms remain obscure. WebJan 1, 2009 · However, to date, the role of endogenous TrkB.T1 is still unknown. By studying mice lacking the truncated TrkB.T1 isoform but retaining normal spatiotemporal expression of TrkB.FL, we have analyzed TrkB.T1-specific physiological functions and its effect on endogenous TrkB kinase signaling in vivo. We found that TrkB.T1-deficient mice develop ...
