The biology of phosphatidylserine is discussed with respect to its role as a global immunosuppressive signal and how PS is exploited to drive diverse pathological processes such as infection and cancer.

It is shown that exposed phosphatidylserine (PS) represents a neuronal ‘eat-me’ signal enabling microglial-mediated synapse pruning and a novel role of developmentally regulated PS exposure that is common among developing brain structures is identified.
It is demonstrated that the mitochondrial protein mitofusin 2 (Mfn2) protects against liver disease and binds phosphatidylserine (PS) and can specifically extract PS into membrane domains, favoring PS transfer to mitochondria and mitochondrialosphatidylethanol

ATG8-PS lipidation provides a specific ‘molecular signature’ for non-canonical autophagy, uncovering a novel means of detecting and monitoring this emerging pathway.
The fusion protein (FP) consisting of L-methionase linked to human Annexin-V has been reported to target the cancer cells, and prevents the methionine (essential amino acid) supplementation to thecancer cells.
It is suggested that a complete understanding of how regulated cell death processes affect the immune system is far from being fully elucidated.
