What strain of mice are athymic?
Nude mice are also athymic; homozygous nude mice lack T cells and suffer from a lack of cell-mediated immunity. Homozygous nude mice show partial defect in B cell development.

Are nude mice genetically modified?
A nude mouse is a laboratory mouse from a strain with a genetic mutation that causes a deteriorated or absent thymus, resulting in an inhibited immune system due to a greatly reduced number of T cells. The genetic basis of the nude mouse mutation is a disruption of the FOXN1 gene.
Are nude mice immunodeficient?
Nude mice were the first immunocompromised mouse strain to be used in cancer research. These strains give insight into multiple forms of immune deficiencies. Charles River offers multiple immunodeficient mice, such as the athymic nude mouse, for use in basic research and nonclinical drug discovery and development.
What does athymic mean?
Athymic: Lacking a thymus gland.
Does nude mice have T cells?
Nude mice do not have T cells. Severe combined immune-deficiency (SCID) mice are lack in both T and B cells.
Why do nude mice not have hair?
The cuticles of the inner root sheath and the hair are not built up, the cortex of the hair being composed by abnormal globular aggregates. These results demonstrate that athymic, nude mice are not hairless but that the development and differentiation of hairs are severely injured in this mouse mutant.
Do athymic mice have B cells?
In its absence, mice are both hairless and athymic. Among these mice are our NSG and NRG mice, which carry a specific mutation in the interleukin 2 receptor gamma subunit gene (Il2rgtm1Wjl) in combination with the Prkdcscid and Rag1tm1Mom, respectively. These mice are B, T and NK cell deficient.
What are athymic rats?
Abstract. Athymic nude rats resemble nude mice in their lack of a normal thymus and functionally mature T cells.
Do athymic mice have T cells?
Nude mice (homozygous for the nu mutation) are athymic, and therefore their major defect is a lack of T cells.
What is a mutant mouse?
Targeted mutant mice are produced by first inducing gene disruptions, replacements or duplications into embryonic stem (ES) cells via homologous recombination between the exogenous (targeting) DNA and the endogenous (target) gene.
