Brain-derived neurotrophic factor (BDNF) is a member of the neurotrophic factor family of signaling molecules. Since its discovery over three decades ago, BDNF has been identified as an important regulator of neuronal development, synaptic transmission, and cellular and synaptic plasticity and has been shown to function in the formation and maintenance of certain forms of memory. Neural plastic...

Genetic and pharmacological studies have suggested that brain-derived neurotrophic factor (BDNF) may be associated with the pathophysiology of bipolar disorder (BD). The present study investigated serum BDNF levels in manic, depressed, euthymic BD patients and in matched healthy controls, using an enzyme-linked immunosorbent assay (sandwich-ELISA). Serum BDNF levels were decreased in manic (p=0...

Huntingtin is a 350-kilodalton protein of unknown function that is mutated in Huntington's disease (HD), a neurodegenerative disorder. The mutant protein is presumed to acquire a toxic gain of function that is detrimental to striatal neurons in the brain. However, loss of a beneficial activity of wild-type huntingtin may also cause the death of striatal neurons. Here we demonstrate that wild-ty...

introduction: brain-derived neurotrophic factor (bdnf) and its receptor, trkb, in the hippocampus are targets for adverse effects of stress paradigms in addition, bdnf and its receptor play key role in the pathology of brain diseases like depression. in the present study, we evaluated the possible role of hippocampal bdnf in depression during pregnancy, methods: to achieve the purpose, repeated...

Various studies have shown that brain-derived neurotrophic factor (BDNF) increases neuronal excitability and is localized and upregulated in areas implicated in epileptogenesis. Seizure activity increases the expression of BDNF mRNA and protein, and recent studies have shown that interfering with BDNF signal transduction inhibits the development of the epileptic state in vivo. These results sug...

Brain-derived neurotrophic factor (BDNF) is the most widely distributed neurotrophin in the CNS, where it plays several pivotal roles in synaptic plasticity and neuronal survival. As a consequence, BDNF has become a key target in the physiopathology of several neurological and psychiatric diseases. Recent studies have consistently reported altered levels of BDNF in the circulation (i.e., serum ...

The effects of antipsychotics on the brain-derived neurotrophic factor (BDNF) expression have been controversial. This study aimed to investigate the effects of chronic quetiapine administration on the BDNF mRNA expression in hippocampus and neocortex of rats with or without immobilization stress. The chronic administration (21 days) of quetiapine (10 mg/kg) significantly attenuated the decreas...

Introduction: The lesser quantity products of reprogrammed stem cells and slower differentiation of stem cells into neurons have limited the advance of cell therapy in clinical applications. Neurotrophic factors BDNF, GDNF, FGF, and IGF are critical factors for further differentiation and proliferation of neuronal cells. However, the influence of the reprogramming genes on the neurotrophic fact...

BACKGROUND: Obesity has been widely associated with structural and functional changes in the brain, whereas inflammation is one of potential mechanisms involved these changes.
 OBJECTIVE: This study aims to prove relationship between serum brain-derived neurotrophic factor (BDNF) levels obesity predictor markers (body mass index waist hip ratio) (interleukin-6 Tumor Necrosis Factor-alpha) ...
