Overview

Also Known As:daniel gray

These ENU-induced Kdelr1 mutant mice exhibit hypopigmentation, reduced thymic cellularity and reduced percentages of CD4+ and CD8+ T cells in the blood. This mutant mouse strain may be useful in studies of T cell development and protein trafficking.

Detailed Description

Homozygotes: Mice that are homozygous for the mutation are viable, fertile, normal in size. Mice exhibit hypopigmentation, reduced thymic cellularity and reduced percentages of CD4+ and CD8+ T cells in the blood. CD8+ T cells display a high expression of the CD44 marker typically expressed on activated and memory T cells. This mutant mouse strain may be useful in studies of T cell development and protein trafficking.

For additional information, see The Scripps Research Institute Mutagenix website.

Heterozygote: Normal

Development

This missense point mutation was generated by ethylnitrosourea (ENU) mutagenesis in C57BL/6J males. Mutagenized males were outcrossed to C57BL/6J females. The mutation results in a A to G transversion at position 644 in exon 4 of 5 exons. The mutation alters the corresponding amino acid from tyrosine to cysteine at codon 158. Upon arrival, mice were bred to C57BL/6J for at least 1 generation to establish the colony.

endocrine/exocrine gland phenotype

thymus hypoplasia

immune system phenotype

abnormal lymphocyte morphology
- increased frequencies of CD8+CD44^hi and CD4+CD44^hi T cells

abnormal response to infection
- Normal - however, mice exhibit normal CD8+ T cell priming and antigen-specific CD8+ T cells expression of intracellular cytokines in response to ex vivo LCMV peptide stimulation
- mice infected with the Armstrong strain of lymphochoriomeningitis virus (LCMV) exhibit reduced CD8+ T cell production of inflammatory cytokine (IFNgamma and TNFalpha) compared with wild-type mice

abnormal T cell differentiation
- intrinsic and moderate impairment from the CD4+CD8+ stage onward

absent NK T cells
- almost absent in the spleen

decreased B cell number

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.
