“Analysis of retinal phospholipids revealed a reduction in phosphatidic acid ( PA ) levels and an associated reduction in phosphatidylinositol (PI) levels.”
“ Phosphatidic acid is also involved in the synthesis of phospholipids and its loss will result in changes to the lipid composition of the inner mitochondrial membrane.”
“In particular, the levels of phosphatidic acid , key precursor of phospholipid synthesis, increased, whereas those of mitochondrial cardiolipin (CL) decreased; in parallel, phospholipid remodeling was induced.”

“We perturbed phospholipid synthesis by activating phospholipase D with sphingosine 1-phosphate (S1P) or inhibiting phosphatidic acid phosphohydrolase by propranolol (Ppl).”
“Upon administration of this phospholipid , the intracellular levels of phosphatidic acid ( PA ) rise with a time course that parallels that of the Ca2+ mobilization, suggesting that PA could be responsible for this Ca2+ signal.”

“Since PA is an important intermediate for de novo biosynthesis of phospholipids , these results reveal a novel mechanism for promoting synthesis of PA enriched in polyunsaturated fatty acids in brain.”

“When the acidic phospholipids phosphatidylserine and phosphatidic acid were incorporated into both vesicles and microemulsions at up to 10 mol % of the total phospholipid , a dose-dependent reduction in the apparent Km was observed.”
