| mice, jimpy | Myelin-deficient mutants which are from the inbred tabby-jimpy strain. (12 Dec 1998) |

| mice, knockout | Mice whose genome contains a gene whose function has been disrupted, or "knocked-out". A common method of producing disabled genes using recombinant DNA technology is by inserting an antibiotic resistance gene into the normal DNA sequence of a clone of the gene being studied. This disrupts the gene's action, thereby preventing it from making an active protein product. Cells in which this transfer is successful are then injected into mouse embryos, producing chimeric mice. These mice are bred to yield a strain in which all the cells contain the knocked-out gene. Knockout mice are used as animal models for various diseases, such as cystic fibrosis, and are helping to clarify the functions of the genes studied within the fields of immunology, cancer genetics, and developmental biology.

| mice, mutant strains | Mice bearing mutant genes which are phenotypically expressed in the animals. (12 Dec 1998) |
| mice, neurologic mutants | Mice which carry mutant genes for neurologic defects or abnormalities. (12 Dec 1998) |
| mice, nude | Mutant mice homozygous for the recessive gene "nude" which fail to develop a thymus. They are useful in tumour studies and studies on immune responses. (12 Dec 1998) |
| mice, obese | Mutant mice exhibiting a marked obesity coupled with overeating, hyperglycaemia, hyperinsulinaemia, marked insulin resistance, and infertility when in a homozygous state. They may be inbred or hybrid. (12 Dec 1998) |
| mice, quaking | Mice homozygous for the mutant autosomal recessive gene, quaking (qk), associated with disorder in myelin formation and manifested by axial tremors. (12 Dec 1998) |
| mice, scid | Mice homozygous for the mutant autosomal recessive gene "scid" which is located on the centromeric end of chromosome 16. These mice lack mature, functional lymphocytes and are thus highly susceptible to lethal opportunistic infections if not chronically treated with antibiotics. The lack of b- and T-cell immunity resembles severe combined immunodeficiency (scid) syndrome in human infants. Scid mice are useful as animal models since they are receptive to implantation of a human immune system producing scid-human (scid-hu) haematochimeric mice. (12 Dec 1998) |
| mice, transgenic | Laboratory mice that have been produced from a genetically manipulated egg or embryo. The technique involves microinjection of foreign DNA fragments into the nucleus of the fertilised egg and transferring it into the uterus of a foster mother mouse. The inserted gene becomes integrated into every cell and tissue of the developing mouse, including its germ line cells. (12 Dec 1998) |
| SCID mice | <abbreviation> Severe combined immunodeficient mice. (05 Mar 2000) |
| severe combined immunodeficient mice | Mice that lack both T and B lymphocytes and are used for transplantation and study of human lymphoid tissues resulting in a SCID-human mouse chimera. See: severe combined immunodeficiency. (05 Mar 2000) |
| New Zealand mice | Inbred strains of mice, either black (NZB) or white (NZW), unique among strains used in experimental immunology because of their proclivity to spontaneous immunologic abnormalities and disorders including systemic lupus erythematosus similar to that found in humans. (05 Mar 2000) |
| NOD mice | Nonobese diabetic mice. Have unique histocompatibility antigens, pancreatic beta cells are destroyed by an autoimmune response. (14 Oct 1997) |
| nude mice | Strains of athymic mice bearing the recessive allele nu/nu which are largely hairless and lack all or most of the T-cell population. Show no rejection of either allografts or xenografts. Nu/nu alleles on some backgrounds have near normal numbers of T-cells. (18 Nov 1997) |
| transgenic mice | Mice that have a piece of foreign lincor DNA integrated into their genome. (05 Mar 2000) |
