LGALS1 and peritonitis: In this study, we detected an elevation of Gal-1 expression in F4/80+Ly6C- peritoneal macrophages accompanied with decreased expression in their monocyte precursors 48 h after the onset of spontaneously-resolving peritonitis (Bannenberg et al., 2005; Cash et al., 2009), indicating a possible role in the initiation of the resolution of inflammation.
