immune system
N
• normal dendritic cell migration and IL-12 production in response to a microbial antigen (STAg)
• normal Langerhans cell migration and APC function in response to contact sensitizer (oxazolone)
• mice exhibit a reduction in the number of total monocytes compared with wild-type mice
• Gr1low monocytes are reduced 3-fold compared to in wild-type mice
• however, expression of Tg(S100A8-BCL2)1Lgs restores monocyte numbers
• following kidney ischemia and reperfusion, mice exhibit reduced monocyte egress from the blood into the inflamed kidney compared with similarly treated wild-type mice
• following kidney ischemia and reperfusion

homeostasis/metabolism
• following kidney ischemia and reperfusion, mice exhibit decreased kidney injury, tubular cell necrosis, and macrophage recruitment compared with similarly treated heterozygous mice

vision/eye
• following laser injury, more subretinal microglial cells accumulate adjacent to the choroid scar than in similarly treated wild-type mice and choroid neovascularization is twice as much as in similarly treated wild-type mice
• subretinal microglial cells accumulate with age in the retina unlike in wild-type mice
• following laser injury, more subretinal microglial cells accumulate adjacent to the choroid scar than in heterozygous mice at 7 and 14 days post injury

renal/urinary system
• following kidney ischemia and reperfusion, mice exhibit decreased kidney injury, tubular cell necrosis, and macrophage recruitment compared with similarly treated heterozygous mice

nervous system
N
• normal neuronal-glial cross talk indicated by microglial response to peripheral nerve injury, 129P2/OlaHsd and C57BL/6 mixed genetic background

cardiovascular system
• following laser injury, more subretinal microglial cells accumulate adjacent to the choroid scar than in similarly treated wild-type mice and choroid neovascularization is twice as much as in similarly treated wild-type mice

hematopoietic system
• mice exhibit a reduction in the number of total monocytes compared with wild-type mice
• Gr1low monocytes are reduced 3-fold compared to in wild-type mice
• however, expression of Tg(S100A8-BCL2)1Lgs restores monocyte numbers
• following kidney ischemia and reperfusion, mice exhibit reduced monocyte egress from the blood into the inflamed kidney compared with similarly treated wild-type mice
• following kidney ischemia and reperfusion

cellular
• following kidney ischemia and reperfusion
