The TrkB receptors are tyrosine kinases and their interaction with APP may phosphorylate the latter. To test this possibility, we conducted cotransfection with GST-APP in the presence of YFP-tagged TrkB wild-type (WT) or kinase-dead mutant (K572R), followed by BDNF treatment. GST pulldown assay … See more BDNF/TrkB signaling is implicated in AD pathologies, but how the neurotrophic pathway contributes to disease onset remains incompletely clear. To explore … See more We have reported that AEP (asparagine endopeptidase, gene name LGMN) acts as δ-secretase, cleaving numerous effectors implicated in AD, including APP, … See more To further explore these biochemical events, we prepared human neurons, induced from healthy control or AD patients’ iPSCs. Immunoblotting revealed that … See more WebThe compound also elicited phosphorylation in TrkB but not in TrkA or TrkC. Kinase-dead TrkB-KD displayed negligible phosphorylation compared with wild-type TrkB (Fig. 3B), indicating that TrkB phosphorylation by 7,8-dihydroxyflavone is through the receptor autophosphorylation but not by any other tyrosine kinases. A binding assay demonstrated ...

Brain-Derived Neurotrophic Factor Increases Synaptic Protein
WebTrkB is a tyrosine kinase receptor that is activated upon binding to brain-derived neurotrophic factor (BDNF). To date, the search for low-molecular-weight molecules … WebOct 29, 2024 · Interestingly, although BDNF is known to rapidly activate TrkB phosphorylation within 5 min (Marsh et al., 1993), the interaction between TrkB and p75 NTR was minimal after 5 min of BDNF treatment, and was only increased after 15 and 30 min of treatment, indicating that association of TrkB with p75 NTR occurred after TrkB … WebFeb 1, 2012 · Rett syndrome (RTT) results from loss-of-function mutations in the gene encoding the methyl-CpG-binding protein 2 (MeCP2) and is characterized by abnormal motor, respiratory and autonomic control, cognitive impairment, autistic-like behaviors and increased risk of seizures.
