The effect of polar head group substitution on phospholipid methylation and the beta-adrenergic response in C6 glial cells.
The membranes of intact C6 cells were enriched with phosphatidyldimethylethanolamine or phosphatidylmonomethylethanolamine. These cells showed enhanced rates of phospholipid methylation but this was not accompanied by an increased beta-adrenergic response. We conclude that phospholipid methylation is not coupled to the activation of adenylate cyclase in the beta-adrenergic response of C6 glial cells.
