  • Ceramide is a novel second messenger generated by hydrolysis of membrane sphingomyelin by a neutral sphingomyelinase (nSMase). Cytokines such as tumor necrosis factor-α (TNF-α) have been shown to increase intracellular ceramide through phospholipase A2(PLA2)-dependent activation of nSMase. TNF-α has been shown to cause endothelium-independent relaxation in isolated blood vessels. We have previously shown that exogenously applied sphingomyelinase and ceramide cause endothelium-independent… CONTINUE READING
