000482 B6.MRL-Faslpr/J
Level 3
Mice homozygous for the lymphoproliferation spontaneous mutation (Faslpr) show systemic autoimmunity, massive lymphadenopathy associated with proliferation of aberrant T cells, arthritis, and immune complex glomerulonephrosis. Onset and severity of symptoms associated with the Faslpr allele is strain-dependent. For example, lymphoproliferation varies greatly with congenic strain C57BL/6J-Faslpr/Faslpr at a 24 fold increase over control lymph node weight, MRL/Mp-Faslpr/Faslpr at 75 fold and congenic strain C3H/HeJ-Faslpr/Faslpr highest at 116 fold increase over control lymph node weight (Morse et al 1985). Variance in renal pathology ranks from extensive in MRL/Mp-Faslpr/Faslpr at 4 to 7 months to negligible at 14 to 16 months in mice with C57BL/6J and C3H/HeJ backgrounds and homozygous for Faslpr > .....

000485 MRL/MpJ-Faslpr/J
Level 4
Mice homozygous for the lymphoproliferation spontaneous mutation (Faslpr) show systemic autoimmunity, massive lymphadenopathy associated with proliferation of aberrant T cells, arthritis, and immune complex glomerulonephrosis. Starting at about three months of age, levels of circulating immune complexes rise greatly in the MRL-lpr/lpr mouse but not the MRL normal (Hewicker 1990). Onset and severity of symptoms associated with the Faslpr gene is strain-dependent. For example, lymphoproliferation varies greatly with congenic strain C57BL/6J-Faslpr/Faslpr at a 24 fold increase over control lymph node weight, MRL/Mp-Faslpr/Faslpr at 75 fold and congenic strain C3H/HeJ-Faslpr/Faslpr highest at 116 fold increase over control lymph node weight (Morse et al 1985). Variance in renal pathology ranks from extensive in MRL/Mp-Faslpr > .....

001876 CBA/KlJms-Faslpr-cg/J
Repository- Live
Mice homozygous for the lymphoproliferation complementing gld spontaneous mutation (Faslpr-cg) are viable and fertile. Homozygous mutant mice are characterized by massive lymphadenopathy. Faslpr-cg complemented both Faslpr and the Faslgld mutation in that double heterozygotes with either mutation had lymphadenopathy. However, further crosses showed the new mutation to be an allele at Faslpr. Like Faslpr and Faslgld homozygotes, CBA/KlJms-Faslpr-cg homozygotes produce antibodies to some nuclear antigens, such as dsDNA, ssDNA, and poly(ADP-ribose); however, they do not produce anti-erythrocyte antibodies. Although they exhibit lymphoid cell infiltration around blood vessels in lung, liver, and kidney, they lack the immune-complex glomerulonephritis, vasculitis, and interstitial pneumonia characteristic of Faslpr homozygotes.
006825 MRL/MpJ-Faslpr/2J
Repository- Live
The current colony (as of fall 2006) of MRL/MpJ-Faslpr/J has experienced a progressive loss of lymphoproliferative phenotype over the past several years, as reported by some of our customers and as observed by our technical staff. This loss of phenotype has been manifested by reduced enlargement of brachial and mesenteric lymph nodes, and poor splenomegaly. Also, the life spans of the mice in the current colony have also been found to be much longer than the historically observed and reported 17 weeks for females and 22 weeks for males. However, genotyping continues to show that all the mice in the colony remain homozygous for the Faslpr mutation, and the SNP profile in the region of the mutation on Chromosome 19 has not changed.

In an effort to regenerate the desired phenotype, we recovered mice from our embryo archive cryopreserved in 1993. The sixteen-week old cryo-recovered mice have lymph nodes that were 4.5 (females) to 10.1 times (male) la .....

002455 MRL-Faslpr.129P2(B6)-B2mtm1Unc
Repository-Cryopreserved
Mice homozygous for both the lymphoproliferation spontaneous mutation (Faslpr) and the B2mtm1Unc targeted mutation are viable and fertile. Class I molecule-deficient B2mtm1Unc mice were backcrossed to MRL/MpJ-Faslpr to study the role of MHC class I molecules in the development of systemic autoimmune disease. Double homozygous mutant mice demonstrated a substantial reduction in CD4-CD8- T cells and a diminution of autoimmune disease. Specifically, hypergammaglobulinemia; autoantibodies including anti-DNA, anti-Smith antigen, and rheumatoid factor; and glomerulonephritis were significantly reduced compared to MRL/MpJ-Faslpr homozygous mice. Moreover, the pattern of hypergammaglobulinemia suggests that the requirement for MHC class I proteins is restricted temporally to later stages of the disease.

003896 MRL/MpJ Faslpr-Foxq1sa-J/J
Repository-Cryopreserved
MRL/MpJ, and one of its ancestral strains LG/J, display heightened wound healing relative to a panel of other inbred strains. At 4 weeks post-injury, 2mm ear punch wounds healed to 0-0.4mm in MRL/MpJ mice but were still 1.2-1.6mm in C57BL/6 mice. At 15 days post-injury C57BL/6 showed a maximal closure of 30% reduction in ear hole size while MRL showed 85% reduction. The process of healing in MRL/MpJ mice was faster, more complete, showed increased swelling, angiogenesis, fibroblast migration, extracellular matrix deposition, and decreased scarring and fibrosis. Additionally, hair follicles and accompanying sebaceous glands were regenerated to a much greater degree. The other ancestral strains of MRL/MpJ (C3H, C57BL/6, and AKR) do not display this enhanced healing. Bone marrow transplantation showed that the MRL/MpJ healing phenotype did not readily transfer with bone marrow and did remain in the irradiated host tissues. Enhanced healing of cardiac wounds has also been reported in MRL/M .....

004519 NOD.MRL(C3)-Faslpr/DoiJ
Repository-Cryopreserved
NOD mice homozygous for the Tnfrsf6 lpr mutation are deficient in Fas antigen expressed on cell surfaces, and the disruption of the Fas-mediated apoptotic pathway results in severe lymphoma in NOD by 4 months of age. This lymphoma is characterized by an expansion of unusual CD4 -, CD8 -, CD3 low , B220 + lymphocytes.
Forty week-old NOD mice homozygous for the Tnfrsf6 lpr mutation are completely protected from spontaneous diabetes and insulitis (as compared to 68% diabetes incidence in the control NOD), even after adoptive transfer of lymphocytes from diabetic NOD mice (0% diabetes incidence 12 weeks post transfer, as compared to NOD controls with 85% incidence 12 weeks post transfer). Recent evidence indicates that Fas-deficient NOD mice are resistant to the adoptive transfer because the abnormal subset of CD4 -, CD8 -, CD3 low , B220 + lymphocytes .....

008517C57BL/6-Gt(ROSA)26Sortm3(CAG-MIRN17-92,-EGFP)Rsky/J
Under Development for Production
Mice homozygous for the "miR-17-92 transgene" conditional allele are viable and fertile, with a loxP-flanked Neo-STOP cassette preventing transcription of the downstream bicistronic sequences (human miR-17-92 cluster (encoding the precursor of seven miRNA molecules; miR-17-5p, miR-17-3p, miR-18a, miR-19a, miR-20a, miR-19b and miR-92) and EGFP). When bred to mice that express Cre recombinase, the resulting offspring will have the STOP cassette deleted in the cre-expressing tissue(s); resulting in expression of the human miR-17-92 cluster. Because the synthetic CAG promoter driven miR-17-92 transgene was targeted for insertion into the Gt(ROSA)26Sor locus, expression of the transgene is determined by which tissue(s) express Cre recombinase. EGFP fluorescence, however, is not reported following exposure to Cre recombinase (presumably due to RNaseIII excision of the stem-loop structures encoding individual miRNA destabilizing the EGFP portion of the primary transcript .....

New Strains Under Development The Jackson Laboratory serves as a worldwide distributor and national repository for common and rare strains of inbred mice and mice carrying spontaneous mutations or induced mutations (i.e., transgenic, targeted/"knockout", or chemically induced mutations). At any one time, we have over 100 strains at various stages of development and colony expansion. Strains "Under Development" fall into two categories depending on the anticipated demand from the scientific community.
  1. Strains that will be made available from a live distribution colony at The Jackson Laboratory.
    These strains are designated as: "Under Development for Distribution Colony"
  2. Strains that will be made available through the Cryopreservation Repository.
    These strains are designated as: "Under Development for Cryopreservation Repository"
It is VERY IMPORTANT that you register interest in strains Under Development. The anticipated demand for a strain enables us to determine effectively the distribution plan for each strain Under Development. Registering interest also provides benefits to you (including advance notification of pending availability). Whether a strain is made available from a live colony OR from our cryopreservation repository, you may want to consider the option of Dedicated Supply. To learn more about Dedicated Supply, go to Services.
