| Bioactivity | Phosphatidylserine is a conserved anti-inflammatory and immunosuppressive signal that is highly dysregulated in the tumor microenvironment and autoimmune diseases. During apoptosis and cellular stress，the related disrupting enzymes Xkr8 and TMEM16 mediate Phosphatidylserine externalization. Phosphatidylserine externalization produces a "eat me" signal that initiates endocytosis and helps clear the body of apoptotic cells. When pathogens use Phosphatidylserine and apoptotic mimicry to evade host immune responses，targeting Phosphatidylserine strategies can stimulate immune activity[1]. |
