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...

Castration of adult male rats causes dendrites of the spinal nucleus of the bulbocavernosus (SNB) to retract. The neurotrophin brain-derived neurotrophic factor (BDNF) is implicated in mediating these androgenic effects on SNB dendrites. We previously found that castration decreases BDNF mRNA in SNB somata and BDNF protein in proximal SNB dendrites, effects not observed in nearby retrodorsolate...

In skeletal muscle, brain-derived neurotrophic factor (BDNF) has long been thought to serve as a retrograde trophic factor for innervating motor neurons throughout their lifespan. However, its localization in mature muscle fibers has remained elusive. Given the postulated roles of BDNF in skeletal muscle, we performed a series of complementary experiments aimed at defining the localization of B...

A sensitive immunohistochemical technique was used, along with highly specific affinity-purified antibodies to brain-derived neurotrophic factor (BDNF), to generate a detailed mapping of BDNF immunoreactivity (BDNF-ir) throughout the adult rat CNS. A parallel analysis of sites of BDNF synthesis was performed with in situ hybridization techniques using a cRNA probe to the exon encoding mature ra...

The clinical application of doxorubicin (Dox) is limited by its adverse effect of cardiotoxicity. Previous studies have suggested the cardioprotective effect of brain-derived neurotrophic factor (BDNF). We hypothesize that BDNF could protect against Dox-induced cardiotoxicity. Sprague Dawley rats were injected with Dox (2.5 mg/kg, 3 times/week, i.p.), in the presence or absence of recombinant B...

BACKGROUND Patients with obstructive sleep apnoea syndrome (OSAS) often display persistent cognitive dysfunction despite effective treatment with continuous positive airway pressure (CPAP). Brain-derived neurotrophic factor (BDNF) is a key mediator of memory and cognition, but its regulation in OSAS and during CPAP treatment is unknown. METHODS Serum and plasma BDNF concentrations, BDNF secre...
