Brain-derived neurotrophic factor (BDNF) and its receptor, tropomyosin-related kinase receptor B (TrkB), play a critical role in memory extinction. However, the detailed role of BDNF in memory extinction on the basis of neural circuit has not been fully understood. Here, we aim to investigate the role of BDNF signaling circuit in mediating conditioned taste aversion (CTA) memory extinction of t...
Moods and metabolism modulate each other. High comorbidity of depression metabolic disorders, such as diabetes obesity, poses a great challenge to treat conditions. Here we report the therapeutic efficacy brain-derived neurotrophic factor (BDNF) by gene transfer in dorsal raphe nucleus (DRN) chronic unpredictable mild stress model (CUMS) models obesity. In CUMS, BDNF-expressing mice displayed a...
Brain-derived neurotrophic factor (BDNF) is a neurotrophin presented widely in central nervous system (CNS). The general function of BDNF in CNS is maintaining neuronal viability in ischemic condition, as well as providing neuronal plasticity and modulating behavioral activity. BDNF regulates axonal growth and differentiation of neurons; synapse formation; activity of dopaminergic, serotoninerg...
Many studies have suggested that brain-derived neurotrophic factor (BDNF) is involved in the reward system of addiction, and that nicotine may induce alterations in BDNF gene expression and its protein level within the mesocorticolimbic system. We investigated the BDNF levels and biochemical-hematological parameters of smoker and non-smoker groups, and examined the association of the Val66Met B...
BACKGROUND Impaired neuronal plasticity and, specifically, altered expression of brain-derived neurotrophic factor (BDNF) were shown to play a critical role in depressive behavior and the mechanism of various antidepressant treatments including electroconvulsive therapy (ECT). Interestingly, opposing roles were suggested for BDNF in the hippocampus and the ventral tegmental area (VTA), while in...
Recent studies have suggested that brain-derived neurotrophic factor (BDNF) is associated with energy balance, eating behaviors, and psychological states such as depression. Although decreased BDNF levels in patients with bulimia nervosa (BN) have been reported, the mechanism is still unclear. Few studies have investigated longitudinal changes of BDNF in BN patients. We investigated changes in ...
Brain-derived neurotrophic factor (BDNF) is essential for neuronal survival and differentiation during development and for synaptic function and plasticity in the mature brain. BDNF-containing vesicles are widely distributed and bidirectionally transported in neurons, and secreted BDNF can act on both presynaptic and postsynaptic cells. Activity-dependent BDNF secretion from neuronal cultures h...
Brain-derived neurotrophic factor (BDNF) importantly regulates learning and memory and supports the survival of injured neurons. Reduced BDNF levels have been detected in the brains of Alzheimer's disease (AD) patients but the exact role of BDNF in the pathophysiology of the disorder remains obscure. We have recently shown that reduced signaling of BDNF receptor TrkB aggravates memory impairmen...
Cultured neurons from bdnf-/- mice display reduced densities of synaptic terminals, although in vivo these deficits are small or absent. Here we aimed at clarifying the local responses to postsynaptic brain-derived neurotrophic factor (BDNF). To this end, solitary enhanced green fluorescent protein (EGFP)-labeled hippocampal neurons from bdnf-/- mice were compared with bdnf-/- neurons after tra...
Brain-derived neurotrophic factor (BDNF) is abundant in the hippocampus and plays critical roles in memory and synapse formation, as well as exerting antidepressant-like effects in psychiatric disorders. We previously reported that BDNF is expressed in salivary glands and affects blood BDNF content. However, the function of salivary BDNF remains unclear. The aim of this study was to generate tr...
