Lipid composition of lymphocyte plasma membrane from pig mesenteric lymph node.

1. The lipid fraction of the plasma membrane of pig mesenteric lymph-node lymphocytes contained primarily (94%) neutral lipids and phospholipids in about equal weights. The remianing lipid comprised glycosphingolipids (1.8%), gangliosides (o.27%)and probably ceramides (1.3%).The major phospholipid was phosphatidylcholine (46% of the total), and mono- and tri-hexosylceramides accounted for 72% of the glycosphingolipids. Haematoside was distributed between the glycosphingolipid and ganglioside fractions. The major ganglioside was monosialoganglioside. About 90% of the sialic acid was N-glycollylated. 2. A comparision of the lipid composition of the plasma-membrane fraction with that of the initial lymph-node homogenate showed that the purified membrane contained increased proportions of phospholipids, especially sphingomyelin, glycosphingolipids and gangliosides. 3. Fatty acid analyses showed that the membrane phosphatidylcholine was rich in palmitic acid, that the sphingomeyelin and phosphatidylethanolamine were high in myristic acid and that the glycosphingolipids were rich in oleic acid.[1]
