No standalone side-effect or combination signal is currently clear enough to show from the collected papers. This does not mean there is no concern.

Evidence summaries

Paper IDs and full lists are private. Only study types and summaries are shown.

Key Evidence #1
Public scholarly dataCitation signal: 634
review

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.

Key Evidence #2
Public scholarly dataCitation signal: 353
observational

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.

Key Evidence #3
Public scholarly dataCitation signal: 341
observational

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

observational

ATG8-PS lipidation provides a specific ‘molecular signature’ for non-canonical autophagy, uncovering a novel means of detecting and monitoring this emerging pathway.

Public scholarly dataCitation signal: 173
review

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.

Public scholarly dataCitation signal: 163
review

It is suggested that a complete understanding of how regulated cell death processes affect the immune system is far from being fully elucidated.
