immune system
• following exposure to Sendai virus, leukocyte and more specifically neutrophil recruitment is decreased compared to in wild-type mice
• following exposure to Sendai virus
• following exposure to Sendai virus
• elevated intraperitoneal levels
• serum levels become very high after 24 hours
• following exposure to Sendai virus, CXCL2 levels are reduced compared to in wild-type mice
• however, CXCL1, CXCL5 and CXCL15 levels are normal following exposure to Sendai virus
• following exposure to Sendai virus, mice exhibit less severe weight loss than wild-type mice and decreased peribronchial inflammation
• following exposure to Sendai virus, mice exhibit higher viral load and reduced total cell numbers, specifically neutrophils, in bronchoalveolar lavage compared to wild-type mice
• however, mice clear viral load by day 21 post-infection by a normal cytotoxic T cell response and adoptive transfer of wild-type neutrophils into mice can restore the normal response to Sendai virus infection
• improved survival following cecal ligation and puncture
• initial weight loss greater than in controls but other indications of organ dysfunction are similar to controls
• bacterial load in peritoneum becomes higher than controls by 24 to 48 hours after experimental manipulation and persists for several weeks

homeostasis/metabolism
• following exposure to Sendai virus
• elevated intraperitoneal levels
• serum levels become very high after 24 hours
• following exposure to Sendai virus, CXCL2 levels are reduced compared to in wild-type mice
• however, CXCL1, CXCL5 and CXCL15 levels are normal following exposure to Sendai virus

growth/size/body
• initial weight loss following cecal ligation and puncture is greater than in controls

cellular
• following exposure to Sendai virus, leukocyte and more specifically neutrophil recruitment is decreased compared to in wild-type mice

hematopoietic system
• following exposure to Sendai virus, leukocyte and more specifically neutrophil recruitment is decreased compared to in wild-type mice
• following exposure to Sendai virus
