Upon activation, brain microglial cells release proinflammatory mediators, such as TNFalpha, which may play an important role in eliciting neuroinflammatory processes causing brain damage. As cannabinoids have been reported to exert anti-inflammatory and neuroprotective actions in the brain, we here examined the effect of both synthetic and endogenous(More)
Several lines of evidence indicate that perturbed cellular Ca2+ homeostasis may play a prominent role in synaptic dysfunction and neuronal death in Alzheimer's disease (AD), suggesting a potential benefit of drugs capable to stabilize Ca2+ homeostasis. We here investigated the effects of a panel of L-type Ca2+ channel antagonists on the secretion of the(More)
We here investigated the effect of the catecholaminergic neurotransmitter dopamine (DA), on the release of two major inflammatory effectors, TNF-alpha and nitric oxide, in rat astroglia-enriched cultures stimulated with the bacterial endotoxin lipopolysaccharide (LPS). Upon LPS challenge, we observed a dramatic increase in the culture medium of the(More)
