Detailed Description

The signal and all of the immunoglobulin (Ig)-V-like exon of the CD274 antigen (Cd274) gene were replaced with a neomycin resistance cassette, abolishing PD-L1 gene expression. PD-L1 is one of two ligands for PD-1 and is upregulated on antigen presenting cells (APCs), activated T cells, myeloid cells, dendritic cells (DCs). It is also expressed on hematopoietic and parenchymal cells. PD-1 is an inhibitory receptor expressed on activated lymphocytes, regulates tolerance and autoimmunity by negative regulation of T cell responses. On the NSG background, mice should be immunodeficient. They should have no mature T cells or B cells, lack functional natural killer (NK) cells, have reduced numbers of lymphocytes and myeloid dendritic cells, and be deficient in cytokine signaling.

In an attempt to offer alleles on well-characterized or multiple genetic backgrounds, alleles are frequently moved to a genetic background different from that on which an allele was first characterized. It should be noted that the phenotype of these congenic mice could vary from that originally described. We may modify the strain description if necessary as published results become available.

Development

A targeting vector was designed to replace the signal and all of the immunoglobulin (Ig)-V-like exon of the CD274 antigen (Cd274) gene with a neomycin resistance cassette. This construct was electroporated into C57BL/6-derived embryonic stem (ES) cells and correctly targeted ES cells were injected into blastocysts. The resulting chimeric animals were bred together to generate a colony of PD-L1- mice. The mutant mice were then backcrossed with NOD/LtJ inbred mice for at least 15 generations. The donating investigator reports that these mice are confirmed homozygous for Idd 1, 2, 3, 4, 5a, 5d, 7, 8, 9, 10, 11, 12, 13, 14, 15 loci after speed congenic backcross to NOD/LtJ. Upon arrival at The Jackson Laboratory Repository, mice were bred to NOD/ShiLtJ inbred mice (Stock No. 001976) for at least one generation and are maintained as 018307. Some mice were also backcrossed to NSG mice (Stock No. 005557) and are maintained as this Stock No. 027905.

Breeding Considerations

When maintaining the live congenic colony, females that are homozygous for Prkdc^scid and Il2rg^tm1Wjl are bred to males that are homozygous for Prkdc^scid and hemizygous for Il2rg^tm1Wjl (Il2rg is an X-linked gene). Cd274^tm1Shr allele should be maintained as heterozygous in the colony due to lethality issues.

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.
