Brain-derived neurotrophic factor (BDNF) is a member of the nerve growth factor family of neurotrophins and plays a vital role in synaptic plasticity. This study investigated the involvement of the amygdaloid BDNF system in molecular mechanisms underlying anxiety and alcohol-drinking behaviors. Male Sprague Dawley rats were cannulated targeting central amygdala (CeA), medial amygdala (MeA), or ...

Adverse childhood experiences (ACEs) may predict markers of neurocognitive performance (i.e., executive function; EF) and brain health/plasticity brain-derived neurotrophic factor; BDNF). This pilot examined: (1) ACES history current EF performance, (2) ACEs BDNF levels, (3) levels. We hypothesized that higher would be associated with lower scores these patterns serum Given the nature study, em...

Introduction Psychotherapy is a treatment of proven efficacy in bipolar disorder (BD), but little known about the molecular and cellular mechanisms that it produces brain. Brain-derived neurotrophic factor (BDNF) thought to be important neuroplasticity could increased by psychopharmaceuticals psychotherapy BD patients, evidence literature limited. Objectives To analyze scientific studies relate...

Besides neuronal plasticity, the neurotrophin brain-derived neurotrophic factor (BDNF) is also important in vascular function. The BDNF has been associated with angiogenesis through its specific receptor tropomyosin-related kinase B (TrkB). Additionally, Val66Met polymorphism decreases activity-induced BDNF. Since BDNF and TrkB are expressed in vascular endothelial cells and aerobic exercise tr...

Acute intrahippocampal infusion of brain-derived neurotrophic factor (BDNF) leads to long-term potentiation (BDNF-LTP) of synaptic transmission at medial perforant path-->granule cell synapses in the rat dentate gyrus. Endogenous BDNF is implicated in the maintenance of high-frequency stimulation-induced LTP (HFS-LTP). However, the relationship between exogenous BDNF-LTP and HFS-LTP is unclear....

Brain derived neurotrophic factor (BDNF) promotes cholinergic neuron function and survival. In Alzheimer's disease, BDNF mRNA and protein are decreased in basal forebrain cholinergic neuron target tissues such as cortex and hippocampus. Using RT-PCR, we demonstrate that BDNF is synthesized in basal forebrain, supplying cholinergic neurons with a local as well as a target-derived source of this ...

Depression is a serious and potentially life-threatening mental disorder with unknown etiology. Emerging evidence shows that brain-derived neurotrophic factor (BDNF) and microRNAs (miRNAs) play critical roles in the etiology of depression. Here this study was aimed to identify and characterize the roles of BDNF and its putative regulatory miRNAs in depression. First, we identified that miR-182 ...

In the mammalian brain, the neurotrophin brain-derived neurotrophic factor (BDNF) has emerged as a key factor for synaptic refinement, plasticity and learning. Although BDNF-induced signaling cascades are well known, the spatial aspects of the synaptic BDNF localization remained unclear. Recent data provide strong evidence for an exclusive presynaptic location and anterograde secretion of endog...

the aim of this study was to investigate the effect of acute plyometric exercise with and without vitamin c supplementation on serum bdnf concentration in inactive men. in this semi-experimental study, 36 inactive men were randomly divided into four groups: vitamin+exercise (combination), vitamin c, exercise, and control. the exercise and combination groups performed the selected plyometric pro...

objective(s): exposing to stress may be associated with increased production of reactive oxygen species (ros). therefore, high level of oxidative stress may eventually give rise to accumulation of oxidative damage and development of numerous neurodegenerative diseases. it has been presented that brain-derived neurotrophic factor (bdnf) supports neurons against various neurodegenerative conditio...
