Details

Detailed Description

Rag1 and H2-Ab1 deficient NOD mice carrying transgenes coding for human CD2-CD4 and HLA-DQ8 lack T and B cells, and are diabetes free. Also, unlike the H2-Ab1 deficient, transgenic CD4, HLA-DQ8 mice (see Stock No. 006021), this strain does not develop cardiomyopathy.

This model is useful in adoptive transfer experiments and to understand the role of MHC class II in autoimmunity.

Development

Congenic, H2-Ab1 deficient, NOD mice carrying transgenes coding for CD2-CD4 and DQ8(Stock No. 006021) were crossed to NOD congenic Rag1 deficient mice (Stock No. 003729) and were bred to homozygosity for the H2-Ab1^tm1Gru and Rag1^tm1Mom targeted mutations. The T1DR received NOD.Cg-Rag1^tm1Mom H2-Ab1^tm1Gru Tg(CD2-CD4,HLA-DQA1,HLA-DQB1)1Ell/EllJ in 2006.

Rag1^tm1Mom

Allele Symbol: Rag1^tm1Mom

Allele Name	targeted mutation 1, Peter Mombaerts
Allele Type	Targeted (Null/Knockout)
Allele Synonym(s)	Rag-; Rag^1tm1Mom; RAG-1-; Rag1^-; RAG1^null; Rag-1KO
Gene Symbol and Name	Rag1, recombination activating gene 1
Gene Synonym(s)
Site of Expression	expression is seen in bone marrow derived cell lines.
Strain of Origin	129S7/SvEvBrd-Hprt⁺
Chromosome	2
Molecular Note	A 1356 bp genomic fragment of the Rag1 gene, encoding the nuclear localization signal and the zinc-finger motif, was replaced by a neomycin cassette. A mutant transcript expressed from this allele was detected by Northern blot in bone marrow derived cell lines from homozygous mice.

H2-Ab1^tm1Gru

Allele Symbol: H2-Ab1^tm1Gru

Allele Name	targeted mutation 1, Michael J Grusby
Allele Type	Targeted (Null/Knockout)
Allele Synonym(s)	[KO]Ab^b; A^bbeta^-; Ab1^tm1Gru; Abb-; Abb^tm1; Abeta-; Abeta^b-; C2-; H2-Ab1^-; H2-Ab1^tm1Glm; I-A^b-; IAb^-; IAbeta-; I-Abeta^b-; MHC class II-; MHC-II-deficient; mII^-
Gene Symbol and Name	H2-Ab1, histocompatibility 2, class II antigen A, beta 1
Gene Synonym(s)
Strain of Origin	129S2/SvPas
Chromosome	17
Molecular Note	A neomycin selection cassette was inserted into exon 2. In addition, the ES cell line used was derived from the 129S2/SvPas strain, which carries a deletion in the promoter region of H2-Ea. Consequently, these MHC class II molecule-deficient mice lacked cell surface expression of both class II-A and class II-E MHC proteins.

Expressed Gene	CD4, CD4 molecule, human
Expressed Gene	HLA-DQB1, major histocompatibility complex, class II, DQ beta 1, human
Strain of Origin	NOD/MrkTac
Chromosome	UN
General Note	Although in NOD mice homozygous for this transgene alone endogeous NOD H2-Abeta^g7 and transgene-derived HLA-DQ8 are expressed at similar levels, virtually all CD4⁺ T-cell responses are H2Abeta1^g7 restricted (J:87013).
Molecular Note	Fertilized oocytes were co-injected with two DNA fragments: a human CD4 cDNA joined to the promoter from the human CD2 gene and a large DNA fragment, reassembled from segments of the cosmid pDCbeta2, containing the human major histocompatibility (MHC) class II alleles HLA-DQA10301 and HLA-DQB0302, which together encode the dimer comprising the HLA-DQ8 molecule, plus 5' regulatory elements. Human CD4 is expressed at a low level on all T cells of transgenic mice. HLA-DQ8 is expressed in homozygous NOD mice at a level comparable to that of the endogenous NOD H2-Abeta^g7 MHC class II molecule in wild-type NOD mice.

Breeding Considerations

When maintaining a live colony, mice homozygous for both targeted mutations and hemizygous for the transgene may be bred together. These mice are immunodeficient and need to be maintained in a high barrier environment with sterile food and water.

Rag1-deficient, H2-Ab1-deficient mice are immunodeficient. As such, and similar to other immunodeficient strains, maintenance in high health status (specific pathogen-free) vivaria promotes overall colony health. If these animals are maintained in low health barrier rooms, the use of medicated water (e.g., sulfatrim/trimethoprim-sulfa or enrofloxacin/Baytril) is suggested to increase overall colony health.

Terms are granted by individual review and stated on the customer invoice(s) and account statement. These transactions are payable in U.S. currency within the granted terms. Payment for services, products, shipping containers, and shipping costs that are rendered are expected within the payment terms indicated on the invoice or stated by contract. Invoices and account balances in arrears of stated terms may result in The Jackson Laboratory pursuing collection activities including but not limited to outside agencies and court filings.

The Jackson Laboratory's Genotype Promise

The Jackson Laboratory has rigorous genetic quality control and mutant gene genotyping programs to ensure the genetic background of JAX® Mice strains as well as the genotypes of strains with identified molecular mutations. JAX® Mice strains are only made available to researchers after meeting our standards. However, the phenotype of each strain may not be fully characterized and/or captured in the strain data sheets. Therefore, we cannot guarantee a strain's phenotype will meet all expectations. To ensure that JAX® Mice will meet the needs of individual research projects or when requesting a strain that is new to your research, we suggest ordering and performing tests on a small number of mice to determine suitability for your particular project. We do not guarantee breeding performance and therefore suggest that investigators order more than one breeding pair to avoid delays in their research.
