immune system
• 24 hours after intraperitoneal injection of thioglycollate a delay in monocyte/macrophage early accumulation is seen; however, monocyte/macrophage numbers are similar to wild-type by 48 hours
• mild monocytopenia in the peripheral blood; however hematopoiesis in the bone marrow is similar to wild-type
• intraperitoneal injection of thioglycollate results in negligible recruitment of lymphocytes into the peritoneum over a 72 hour-period after injection; however neutrophil recruitment is similar to wild-type
• in adoptive transfer experiments homing of lymphoctes to secondary lymphoid tissues is similar to wild-type but recruitment to an inflamed peritoneal cavity is impaired
• however; humoral immune responses are similar to wild-type
• numbers of B2, but not B1, cells are decreased in the peritoneum after intraperitoneal injection of thioglycollate compared to wild-type mice
• the decrease in accumulation of B cells in the inflamed peritoneum is more pronounced than for T cells although both are decreased
• the decrease in accumulation of B cells in the inflamed peritoneum is more pronounced than for T cells although both are decreased
• fewer Peyer's patches are seen in the gut; however those present have normal morphology and proportions of T and B cells
