Phosphatidylserines (PS)

Phosphatidylserine (Phospholipids) is a well-conserved anti-inflammatory and immunosuppressive signal. Phosphatidylserine is involved in membrane translocation and the activation of protein kinase C, participating in Akt signaling through its interaction with PIP3. The local exposure of Phosphatidylserine can interact with complement and other proteins, promoting microglial phagocytosis during critical periods of synaptic refinement. Phosphatidylserine can promote blood coagulation in the extracellular environment and acts as a "eat me" signal to clear out apoptotic cells. Phosphatidylserine can suppress inflammation in tissues by inducing TGF-β secretion and inhibiting immune responses.

Oleoyl-2-hydroxy-sn-glycero-3-phospho-L-serine sodium (18:1 Lyso-PS) is a modified PS product generated following NADPH oxidase activation and Lyso-PS signal transduction. 1-Oleoyl-2-hydroxy-sn-glycero-3-phospho-L-serine sodium signals through macrophage G2A to enhance the phagocytic uptake of PS-dependent apoptotic (apoptosis) neutrophils and PS-exposed activated neutrophils. 1-Oleoyl-2-hydroxy-sn-glycero-3-phospho-L-serine sodium enhances macrophage phagocytic uptake of apoptotic cells, carboxylate-modified microspheres, and PS-exposed non-apoptotic activated neutrophils. 1-Oleoyl-2-hydroxy-sn-glycero-3-phospho-L-serine sodium serves as an acyl acceptor substrate for the lysophosphatidyltransferase At1g78690p to generate diacylphosphatidylserine. 1-Oleoyl-2-hydroxy-sn-glycero-3-phospho-L-serine sodium reduces the secretion of IL-8 and decreases the proportion of viable colon cancer cells. 1-Oleoyl-2-hydroxy-sn-glycero-3-phospho-L-serine sodium is applicable to studies on peritonitis and inflammatory bowel disease.

18:0,18:1 PS sodium is the dominant phosphatidylserine subtype in cells, exosomes and HIV particles. It is abundant in the brain and is essential for maintaining membrane structure, lipid raft organization and intracellular trafficking. 18:0,18:1 PS sodium mediates interleaflet membrane coupling through cholesterol-dependent interactions with very long-chain sphingolipids, and can induce the clustering of glycosylphosphatidylinositol-anchored proteins. In addition, clusters formed by the binding of 18:0,18:1 PS sodium to cholesterol not only facilitate the proper distribution of cholesterol in lipid bilayers, but also effectively protect cholesterol from oxidative damage.
