N normal phenotype
growth/size/body
• mice appear normal at weaning but fail to gain weight

hematopoietic system
• increase in levels of circulating neutrophils
• increase in levels of circulating lymphocytes
• increase in levels of circulating monocytes
• IgG deposition in the glomeruli of kidneys
• macrophages exhibit an acute elevation of proinflammatory cytokines IL-1beta, IL-6, and IP-10, but not IL-10, in response to ingesting dying cells that is not seen in control macrophages
• however, neither bone marrow-derived macrophages nor peritoneal exudate macrophages from 52 week old mice show any defects in the engulfment of dying cells in vitro indicating normal phagocytic capacity

homeostasis/metabolism
• levels of CXCL1, CCL4 and CCL2 are increased in 52-week old mice

immune system
• increase in levels of circulating neutrophils
• increase in levels of circulating lymphocytes
• increase in levels of circulating monocytes
• IgG deposition in the glomeruli of kidneys
• macrophages exhibit an acute elevation of proinflammatory cytokines IL-1beta, IL-6, and IP-10, but not IL-10, in response to ingesting dying cells that is not seen in control macrophages
• however, neither bone marrow-derived macrophages nor peritoneal exudate macrophages from 52 week old mice show any defects in the engulfment of dying cells in vitro indicating normal phagocytic capacity
• levels of CXCL1, CCL4 and CCL2 are increased in 52-week old mice
• mice develop a systemic lupus erythematosus-like disease (SLE)
• increase in serum levels of a broad array of antibodies against autoantigens commonly associated with SLE
• kidneys from aged mice show endocapillary proliferative glomerulonephritis

renal/urinary system
• mice show indications of kidney damage and show increased functional markers of kidney injury
• IgG and complement C1q deposition in the glomeruli of kidneys
• kidneys from aged mice show endocapillary proliferative glomerulonephritis
