Enteric gliopathy in niacin-deficiency induced by CNS glio-toxin.
6-Aminonicotinamide (6-AN), an antagonist of niacin and a potent CNS glio-toxin, selectively caused degeneration of glial cells in the central nervous system (CNS) of rodents. Suckling mice treated with 6-AN developed diarrhea clinically and displayed vacuolated degenerating glial cells in the myenteric plexus as well as in the CNS. Myenteric neurons were well preserved. These findings provide further evidence for possible functional similarities between the glial cells in the central and enteric nervous systems.
