| Research Abstract |
Plasmalogen is a subclass of glycerophospholipids with radical-sensitive chemical structure, and suggested as an endogenous anti-atherogenic factor. Fatty acids with trans form are well-known atherogenic dietary components, however, the mechanisms are not full clarified. We found that a trans-form FA was abundantly incorporated into plasmalogen molecules by feeding of trans fatty acids for 4 weeks in rats. Application of a LDL fraction of trans fatty acid-fed rats to a cultured blood vessel endothelial cell, HUVEC, enhanced gene and protein expression of VCAM1, a adhesion factor for monocyte to blood vessel endothelium, and MCP1, a chemoattractant for monocyte in the cells. These results suggest that trans fatty acids incorporated into plasmalogen is an inducer of the atherogenic changes in the blood vessels.
