Details

Detailed Description

Mice homozygous for the targeted mutation are viable and fertile. Homozygous mutant mice have normal numbers of CD8⁺ T cells and NK cells. CTL and NK cells are unable to lyse virus-infected or allogeneic fibroblasts in vitro. Homozygotes fail to clear lymphocytic choriomeningitis virus. Fibrosarcoma tumor cells are eliminated with reduced efficiency. This mutant mouse strain may be useful in studies of inflammatory response, susceptibility to infection, and susceptibility to multiple sclerosis.

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. This is the case for the strain above. It should be noted that the phenotype could vary from that originally described. We will modify the strain description if necessary as published results become available.

Development

A replacement vector was used containing the neo gene and which resulted in the disruption of exon 3 of the perforin gene without delection of coding sequence. No fully function perforin mRNA was detected by reverse transcription PCR. Male BL/6-III ES cells were used. There cells were originally derived from C57BL/6 mice. The mice were then backcrossed five generations with BALB/cByJ inbred mice (Stock No. 001026).

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.

Disease Terms

Model with phenotypic similarity to human disease where etiologies involve orthologs. Human genes are associated with this disease. Orthologs of those genes appear in the mouse genotype(s).

Model with phenotypic similarity to human disease where etiologies are distinct. Human genes are associated with this disease. Orthologs of these genes do not appear in the mouse genotype(s).
