| 003610 | B6.129S4-Cd80tm1Shr Cd86tm2Shr/J | Repository- Live |
| Cd80/Cd86-mediated signaling is critical to germinal center formation and Ig class switching in vivo. Mice homozygous for both the Cd80 (B7-1) and Cd86 (B7-2) targeted mutations are viable, fertile and have a normal life span. Homozygous null Cd80/Cd86 mice fail to generate antigen specific IgG1 and IgG2a responses. During the postimmunization period (seven-10 days) they have smaller spleens devoid of germinal centers. Unimmunized null mice exhibit a three to five fold reduction in total serum immunoglobulin and IgG2a. Levels of IgG1 are also reduced five to 10 fold. Levels of IgM and IgG3 are elevated three to five fold. When immunized, antigen specific IgG1 and IgG2a isotype levels are 0.1% that of wild-type levels. Levels remain low even when immunization is performed with adjuvent. This strain is also resistant to myelin oligodendrocyte glycoprotein (MOG) 35-55 peptide-induced experimental autoimmune encephalomyelitis (EAE), a T cell-mediat .....

| 003611 | B6.129S4-Cd80tm1Shr/J | Repository- Live |
| Cd80 (B7-1) null mice are viable and fertile. They possess normal numbers of B and T lymphocytes but exhibit a diminished mixed lymphocyte response. Following immunization, antigen specific IgG1, IgG2a and IgM isotypes are 25%-50% that of wild type levels. Survival of certain tissue allografts are slightly prolonged in Cd80 null mice. | ||
| 004673 | NOD.129(B6)-Rag1tm1Mom Cd80tm1Shr/JbsJ | Cryopreserved - Ready for recovery |
| The NOD.129(B6)Rag1tm1MomCd80tm1Shr/JbsJ homozygous mice fail to produce T or B cells. Mice homozygous for both Rag1tm1Mom and Cd80tm1Shr are viable and fertile and exhibit no signs of diabetes due to the absence of lymphocytes. On the NOD background Cd80tm1Shr alone exacerbates diabetes onset when compared to standard NOD controls. When injected with proteolipid protein in Complete Freund's Adjuvant, NOD mice homozygous for the Cd80tm1Shr/JbsJ mutation alone develop similar though slightly milder, experimental autoimmune encephalomyelitis (EAE) when compared with NOD controls. NOD.129(B6)-Rag1tm1MomCd80tm1Shr/JbsJ are valuable for unraveling the co-stimulatory pathways of T cell activation as it relates to autoimmune diseases and organ transplantation. | ||
| 007769 | NOD.FVB-Tg(Igh-6-Cd80)1Gjf/JbsJ | Cryopreserved - Ready for recovery |
| Transgenic mice are viable, fertile, normal in size, normoglycemic and do not display any gross physical or behavioral abnormalities. High levels of the transgene are expressed on B cells, but not on T cells. At 30 weeks of age transgenic mice are diabetes resistant and insulitis was significantly reduced when compared with wildtype NOD controls. When compared to wildtype NOD controls, the circulating B cells in congenic NOD transgenic mice is 2-3 fold lower in 2 week old mice and 10 fold lower in 5-6 week old mice and persists throughout life. Significantly reduced percentage of B cells were found in the spleen and bone marrow. Analysis of bone marrow shows the more mature B cell subsets (B220+, IgM+) are affected. Elisa tests indicate reduced circulating levels of all Ig types, Ighm (formerly Igh-6), Igh-3 (IgG2b), and Ighg1 (IgG1) in the serum of transgenic mice. MHC class II expression of splenic B cells was significantly increased by more than 2 fold, indicati ..... For more information please see the full phenotype on the strain data sheet | ||
