Objective: Authors hypothesized that activation of the endocannabinoid system may confer neuroprotection against cholinergic degeneration.
Summary: Degeneration, induced by 192-IgG-saporin, of baso-cortical cholinergic pathways resulted in memory deficits and decreased cortical levels of lysophosphatidylcholines (LPC). The cannabinoid agonist WIN55,212-2 restored cortical cholinergic transmission and LPC levels via activation of cannabinoid receptors. This activation altered cortical lipid homeostasis mainly by reducing sphingomyelins in lesioned animals. These modifications were crucial for memory recovery.
Usage: Basal forebrain cholinergic degeneration was induced following bilateral stereotaxic injection of 192IgG-saporin (130 ng/μl, IT-01) into the nucleus basalis magnocellularis (NBM).
