Effect of anandamide uptake inhibition in the production of nitric oxide and in the release of cytokines in astrocyte cultures.

abstract：:It has become evident recently only that microglia are not only responsible for immunomodulatory functions in the brain but represent vital components of the larger synaptic formation, which also includes pre and postsynaptic neurones as well as astrocytes. Microglia critically contribute to CNS homeostasis by their a...
