BACKGROUND Dysregulation in the prefrontal cortex-nucleus accumbens pathway has been implicated in cocaine addiction. We have previously demonstrated that one intra-dorsomedial prefrontal cortex brain-derived neurotrophic factor (BDNF) infusion immediately following the last cocaine self-administration session caused a long-lasting inhibition of cocaine-seeking and normalized the cocaine-induce...

Activation of microglia commonly occurs in response to a wide variety of pathological stimuli including trauma, axotomy, ischemia, and degeneration in the CNS. In the retina, prolonged or high-intensity exposure to visible light leads to photoreceptor cell apoptosis. In such a light-reared retina, we found that activated microglia invade the degenerating photoreceptor layer and alter expression...

OBJECTIVE Blood neurotrophins, such as the brain-derived neurotrophic factor, are considered to be of great importance in mediating the benefits of physical exercise. In this study, the effect of acute strength exercise and the involvement of small versus large muscle mass on the levels of plasma brain-derived neurotrophic factor were evaluated in healthy individuals. METHODS The concentric s...

Brain-derived neurotrophic factor (BDNF) supports hippocampal, cortical and basal forebrain cholinergic neurons, which lose function in Alzheimer's disease. In Alzheimer's tissues such as hippocampus and parietal cortex, brain- derived neurotrophic factor mRNA is decreased three- to four-fold compared with controls. However, the molecular mechanism of the down-regulation of BDNF in Alzheimer's ...

Methods. Retinal ischemia was induced in Lewis albino rats by increasing intraocular pressure to 160 mm Hg for 90 minutes. The agents or buffer controls were injected intravitreally at different times, either before or after the ischemic insult, and the postischemic survival time was either 7 or 14 days. The degree of retinal damage was assessed from plastic-embedded sections by cytologic analy...
