BACKGROUND Decreased brain-derived neurotrophic factor (BDNF) has been demonstrated in animal models and patients with depression. However, little is known about changes in BDNF in post-stroke depression (PSD). This study investigated the changes in serum BDNF in patients with PSD, and evaluated whether serum concentrations of BDNF were associated with BDNF gene Val66Met polymorphism. METHODS...

Brain-derived neurotrophic factor (BDNF) regulates the survival and growth of neurons, and influences synaptic efficiency and plasticity. Peripheral BDNF levels in patients with schizophrenia have been widely reported in the literature. However, it is still controversial whether peripheral levels of BDNF are altered in patients with schizophrenia. The peripheral BDNF levels previously reported ...

Brain-derived neurotrophic factor (BDNF) signaling is implicated in the etiology of many psychiatric disorders associated with altered emotional processing. Altered peripheral (plasma) BDNF levels have been proposed as a biomarker for neuropsychiatric disease risk in humans. However, the relationship between peripheral and central BDNF levels and emotional brain activation is unknown. We used h...

BACKGROUND The pathogenic role of brain derived neurotrophic factor (BDNF) in the incisional pain is poorly understood. The present study explores the role of the BDNF in the incision-induced pain hypersensitivity. METHODS A longitudinal incision was made in one plantar hind paw of isoflurane-anesthetized rats. Dorsal root ganglias (DRG) and spinal cords were removed at various postoperative ...

Brain derived neurotrophic factor (BDNF) plays a key role in the growth, development and maintenance of the central and peripheral nervous systems. Exogenous BDNF activates its membrane receptors at the axon terminal, and subsequently sends regulation signals to the cell body. To understand how a BDNF signal propagates in neurons, it is important to follow the trafficking of BDNF after it is in...

Mutations in the MECP2 gene cause Rett syndrome (RTT). Bdnf is a MeCP2 target gene; however, its role in RTT pathogenesis is unknown. We examined Bdnf conditional mutant mice for RTT-relevant pathologies and observed that loss of BDNF caused smaller brain size, smaller CA2 neurons, smaller glomerulus size, and a characteristic hindlimb-clasping phenotype. BDNF protein level was reduced in Mecp2...

To explore the effect of electroacupuncture on spinal cord injury (SCI) involving immune-related factors and regeneration-related in rats. The model contusion was established by PCI 3000 instrument. Two types acupuncture points were selected for treatment rats tested once a week, fiber remodeling detected magnetic resonance imaging. Transcriptome sequencing performed scar samples. Using Python ...

background and purpose: brain-derived neurotrophic factor (bdnf) is present in the hippocampus and cerebral cortex in high concentrations and has an important role in development, maintenance and regeneration of the nervous system. the aim of this study was to produce active bdnf in e.coli using transforming plasmid. methods: to construct an expression plasmid of bdnf, a gene coding for it was ...

Using immunocytochemistry and in situ hybridization, we have examined the expression of brain-derived neurotrophic factor (BDNF) and of neurotrophin receptors in dorsal root ganglion cells. In the adult rat, BDNF mRNA and protein were found mainly in the subpopulation of cells that express the nerve growth factor (NGF) receptor trkA and the neuropeptide calcitonin gene-related peptide (CGRP). N...

PURPOSE A prior study showed that brain-derived neurotrophic factor (BDNF) rescues photoreceptors from collateral retinal damage caused by photodynamic therapy (PDT). This study was conducted to determine whether ciliary neurotrophic factor (CNTF), a combination of BDNF and CNTF, or pigment epithelial cell-derived growth factor (PEDF) might protect photoreceptors and retinal function more effec...
