Phosphatidylserine
Pharmaceuticals and Biotechnology: Therapeutic and Research Applications
Drug Delivery Systems
Liposome Component: As a phospholipid, Phosphatidylserine is used in liposomal drug formulations to enhance stability, targeting, and cellular uptake of medications. For example:
Cancer drugs encapsulated in Phosphatidylserine-containing liposomes can evade immune detection and release payloads directly into tumor cells.
Vaccine Adjuvant: Improves immune response when incorporated into vaccine formulations, enhancing antigen presentation.
Research Tool and Diagnostic Marker
Apoptosis Detection: In cell biology research, Phosphatidylserine exposure on the cell membrane is a hallmark of apoptosis (programmed cell death), making it a key marker for diagnostic assays.
Neurological Disorder Research: Studied as a potential biomarker for Alzheimer’s disease, as brain phosphatidylserine levels decline with disease progression.
