title: Phagocytosis, peritoneal influx, and enzyme activities in peritoneal macrophages from germfree, conventional, and ex-germfree mice.
abstract: Peritoneal macrophages from germfree mice showed a higher basic activity of lysosomal enzymes than did macrophages from conventional mice, whereas oil-induced peritoneal influx, induction of lysosomal enzymes, and phagocytosis via the C3b receptor after endotoxin stimulation were reduced or absent. After germfree mice had been housed with conventional mice for 1 week, peritoneal influx and C3b receptor-mediated phagocytosis reached normal levels; after 4 weeks, enzyme activities also reached normal levels.
