Web1 Introduction. The process of efferocytosis, or engulfment of apoptotic cells (ACs) by phagocytes, has commanded strong interest since the 1990s (Hart et al., 1996; Savill et … WebHowever, efferocytes not only prevent this induction of inflammation but also actively promote a pro-resolving and anti-inflammatory response. MERTK signaling, in addition to driving engulfment of the apoptotic cell, also suppresses inflammatory signaling and promotes the expression of anti-inflammatory cytokines [ 63 , 147 , 189 , 190 ].
