Phagocytosis of neuronal debris by microglia is associated with neuronal damage in multiple sclerosis.

abstract：:Astrocytes play an important role in neuroprotective responses. Recent studies indicate that endothelin-1, a neuropeptide upregulated during brain injury, increases levels of the endocannabinoid anandamide, a lipid with neuroprotective properties, in astrocytes in primary cultures. However, whether this neuropeptide a...
