Ccl2tm1Rol/Ccl2tm1Rol mice with experimental autoimmune encephalomyelitis show fewer inflammatory infiltrates in the spinal cord

immune system
• the timing of macrophage recruitment during tooth eruption is different than in wild-type mice with peak numbers occurring earlier than in wild-type mice
• the total number of macrophages recruited is normal
• mutants show impaired macrophage recruitment to the CNS after MOG35-55 induced EAE (J:68145)
• initially following femoral artery excision (J:118606)
• only half the number of macrophages are recruited to the peritoneum in an induced peritonitis model as occurs in wild-type controls (J:151874)
• 1 and 3 days after femoral artery excision, mice exhibit an earlier increase in neutrophil accumulation (measured by MPO activity) than in similarly treated wild-type mice
• in an EAE model, mutants show an increase in proportion of CD4+ cells and reduction in CD11b+CD4- in the CNS leukocyte infiltrates compared to wild-type, although total numbers of T cells are not different
• at P5 during tooth eruption
• peak osteoclast accumulation occurs at P5 instead of at P9 as in wild-type mice
• numbers of leukocytes isolated from CNS tissue during EAE attacks are about 1/3 of those from wild type mice with comparable EAE severity
• age-dependent accumulation of macrophages in the choroids is less than in wild-type mice
• the number of neutrophils recruited to the peritoneum in an induced peritonitis model is almost double that controls
• at 16 months, IgG is present in the retinal pigmented epithelium or choroids unlike in wild-type mice
• IgG light chain deposition in the retinal pigmented epithelium accumulates with age unlike in wild-type mice
• significantly higher levels of anti-MOG35-55 IgG1 antibodies are seen in mutants compared to wild-type
• 1 day after femoral artery excision, muscles accumulate more chemoattractants (KC and MIP-2) than in similarly treated wild-type mice (J:118606)
• in thioglycollate- or zymosan- induced peritonitis models, no Ccl2 is detected while reduce levels of Ccl7 are present in peritoneal fluid (J:151874)
• MOG35-55-specific Th1 cytokine responses are diminished in mutants
• there is no Ccl2 (MCP-1) secretion by peritoneal macrophages activated in vitro compared to controls
• secretion of Ccl7 (MCP-3) and Ccl12 (MCP-5) is also dramatically reduced by these activated macrophages
• mutants exhibit reduced production of IFN-gamma in response to MOG35-55 induced EAE
• mutants exhibit enhanced secretion of IL-10 in response to MOG35-55 induced EAE
• homozygotes are resistant to active experimental autoimmune encephalomyelitis (EAE) induction with MOG35-55, with delayed onset of disease, reduced inflammatory reaction including impaired recruitment of macrophages to the central nervous system (CNS), and faster and complete recovery
• adoptive transfer of primed T cells from wild-type mice to naive homozygous mutant recipients does not mediate clinical EAE, however wild-type mice receiving mutant T cells do develop clinical EAE

• at 15 to 19 months, mice exhibit intrachoroidal neovascularization with angiographic leakage unlike wild-type mice
• after 18 months, 4 of 15 mice exhibit choroidal neovascularization with angiographic leakage unlike in wild-type mice
• between 18 and 27 months, neovasculatization breaches the Bruch membrane and causes retinal pigmented epithelium and photoreceptor disruptions unlike in wild-type mice
• the Bruch membrane is thickened compared to in wild-type mice after 9 months of age
• at 20 months, the outer Bruch membrane is breached by choriocapillary processes unlike in wild-type mice
• at 16 months, mice exhibit progressive outer retinal degeneration and confluent areas of visible atrophy unlike in wild-type mice
