Role of the brain-derived neurotrophic factor at glutamatergic synapses.

The neurotrophin brain-derived neurotrophic factor (BDNF) plays an important role in the activity-dependent regulation of synaptic structure and function, particularly of the glutamatergic synapses. BDNF may be released in the mature form, which activates preferentially TrkB receptors, or as proBDNF, which is coupled to the stimulation of the p75(NTR). In the mature form BDNF induces rapid effe...

The Pattern of Brain-Derived Neurotrophic Factor Gene Expression in the Hippocampus of Diabetic Rats

Objective(s) The aim of this study was to evaluate the effects of regular exercise in preventing diabetes complication in the hippocampus of streptozotocin (STZ)-induced diabetic rat. Materials and Methods A total of 48 male wistar rats were divided into four groups (control, control exercise, diabetic and diabetic exercise). Diabetes was induced by injection of single dose of STZ. Exercise ...

Endogenous brain-derived neurotrophic factor triggers fast calcium transients at synapses in developing dendrites.

Brain-derived neurotrophic factor (BDNF) is involved in many aspects of the formation of functional neuronal networks. BDNF signaling regulates neuronal development not only globally, at the level of entire neurons or networks, but also at a subcellular level and with high temporal specificity; however, the spatiotemporal characteristics of intrinsic BDNF signaling are essentially unknown. Here...

Role of pro-brain-derived neurotrophic factor (proBDNF) to mature BDNF conversion in activity-dependent competition at developing neuromuscular synapses.

Formation of specific neuronal connections often involves competition between adjacent axons, leading to stabilization of the active terminal, while retraction of the less active ones. The underlying molecular mechanisms remain unknown. We show that activity-dependent conversion of pro-brain-derived neurotrophic factor (proBDNF) to mature (m)BDNF mediates synaptic competition. Stimulation of mo...

Brain-derived neurotrophic factor participates in determination of neuronal laminar fate in the developing mouse cerebral cortex.

Lamina formation in the developing cerebral cortex requires precisely regulated generation and migration of the cortical progenitor cells. To test the possible involvement of brain-derived neurotrophic factor (BDNF) in the formation of the cortical lamina, we investigated the effects of BDNF protein and anti-BDNF antibody separately administered into the telencephalic ventricular space of 13.5-...
