Subsequent analysis of Alox15-expressing resolution-phase macrophages isolated from models of resolving peritonitis and acute N-acetyl-p-aminophenol-induced liver injury indicated a heightened efferocytic capacity (Schif-Zuck et al., 2011; Uderhardt et al., 2012; Yang et al., 2019). This evidence concerns the gene ALOX15 and peritonitis.
