Changes in visual cortical responses that are induced by monocular visual deprivation are a widely studied example of competitive, experience-dependent neural plasticity. It has been thought that the deprived-eye pathway will fail to compete against the open-eye pathway for limited amounts of brain-derived neurotrophic factor, which acts on TrkB and is needed to sustain effective synaptic conne...
Insulin receptor-related receptor (IRR), an orphan receptor in the insulin receptor (IR) family of receptor tyrosine kinases, is primarily localized to neural crest-derived sensory neurons during embryonic development. Expression of IRR closely resembles that of the nerve growth factor receptor, TrkA. To analyze the signaling properties and function of IRR in PC12 cells, a TrkB/IRR hybrid recep...
Brain-derived neurotrophic factor (BDNF) regulates synaptic activity and behavioral flexibility, and reduction of BDNF strongly predicts psychiatric disorders and cognitive dysfunction. Restoration of BDNF-dependent activity could alleviate these impairments, but BDNF has limited clinical utility due to its pharmacokinetics. Here we demonstrate that activation of a primary BDNF target, the trop...
BACKGROUND Although more and more new potent antibiotics have been used, the incidence of neurological sequelae of Streptococcus pneumoniae meningitis has not improved in children over the last decade. The expression of TrkB mRNA, a receptor of brain-derived neurotrophic factor, is associated with the incidence of neurological sequelae of Streptococcus pneumoniae meningitis. METHODS Rats of 3...
The cells of the intervertebral disc (IVD) have an unusual acidic and hyperosmotic microenvironment. They express acid-sensing ion channels (ASICs), gated by extracellular protons and mechanical forces, as well as neurotrophins and their signalling receptors. In the nervous tissues some neurotrophins regulate the expression of ASICs. The expression of ASIC2 and TrkB in human normal and degenera...
AIM Tyrosine kinase receptor-B (TrkB), a high-affinity receptor for brain-derived neurotrophic factor (BDNF), functions via specific binding with the BDNF. Although studies have shown that BDNF promotes the expression of glutamate transporter-1 (GLT-1) in the glial cells during neurodegeneration, evidence is lacking regarding whether BDNF/TrkB pathway is associated with the abnormal function of...
Recent studies suggest that the human Abelson helper integration site-1 (AHI1) gene on chromosome 6 is associated with susceptibility to schizophrenia and autism, two common neuropsychological disorders with depression symptoms. Mouse Ahi1 protein is abundant in the hypothalamus and amygdala, which are important brain regions for controlling emotion. However, the neuronal function of Ahi1 remai...
Intracellular trafficking of receptor proteins is essential for neurons to detect various extracellular factors during the formation and refinement of neural circuits. However, the precise mechanisms underlying the trafficking of neurotrophin receptors to synapses remain elusive. Here, we demonstrate that a brain-enriched sorting nexin, ARHGAP33, is a new type of regulator for the intracellular...
long-term potentiation (ltp) is a process that certain types of synaptic stimulation lead to a long-lasting enhancement in the strength of synaptic transmission. studies in recent years indicate the importance of molecular pathways in the development of memory and learning. tropomyosin receptor kinase b (trkb) is a member of the neurotrophin receptor tyrosine kinase family, that its ligand is b...
Brain-derived neurotrophic factor (BDNF) and its receptors are necessary for the survival and development of many neuronal cells. Because BDNF and TrkB are expressed in many poor-prognosis neuroblastoma (NB) tumors, we evaluated the role of BDNF in affecting sensitivity to chemotherapeutic agents. We investigated the effects of activation of the BDNF-TrkB signal transduction pathway in two NB c...
