Stress can cause damage and atrophy of neurons in the hippocampus by deregulating the expression of neurotrophic factors that promote neuronal plasticity. The endocannabinoid system represents a physiological substrate involved in neuroprotection at both cellular and emotional levels. The lack of CB1 receptor alters neuronal plasticity and originates an anxiety-like phenotype in mice. In the pr...

To begin to identify novel protein(s) that acts on nigral dopaminergic (DA) neurons, we characterized trophic effects of DA-depleted striatum on survival of fetal DA neurons in the present study. Treatment of ventral mesencephalic cultures with the striatal extracts delayed DA cell death in a dose-dependent manner. This effect was partially dependent on brain-derived neurotrophic factor (BDNF),...

Background The popular recreational abuse drug 3,4-methylenedioxymethamphetamine (MDMA, 'Ecstasy') produces acute and long-lasting deficits in several markers of the serotonergic (5-HT) system. BDNF (brain derived neurotrophic factor) is a prominent trophic factor of serotonergic fibers. The aim of this study was to characterize the damage of serotonergic fibers in the frontoparietal cortex and...

We previously reported a case in which steroid-induced psychosis was eliminated with risperidone treatment in a patient with polyarteritis nodosa (PN). In the present report, we longitudinally tracked the serum levels of brain-derived neurotrophic factor (BDNF). We found that corticosteroid lowered serum BDNF levels, and improvement of psychiatric symptoms was intact with the serum BDNF levels ...

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 ...

Axonal injury close to cell bodies of motoneurons induces the death of the vast majority of affected cells. Neurotrophic factors, such as brain derived neurotrophic factor (BDNF) and glial cell derived neurotrophic factor (GDNF), delivered close to the damaged motor pool in a non-regulated manner induce good survival of injured motoneurons and sprouting of their axons but fail to induce functio...

We recently identified brain-derived neurotrophic factor (BDNF) in the dorsal striatum to be a major component of a homeostatic pathway controlling ethanol consumption. We hypothesized that ethanol-mediated activation of the BDNF signaling cascade is required for the ethanol-related function of the neurotrophic factor. Here, we demonstrate that exposure of striatal neurons to ethanol results in...
