| 002287 | B6.129S7-Ifngtm1Ts/J | Level 4 |
| Mice homozygous for the Ifngtm1Ts targeted mutation are viable and fertile. Homozygotes appear normal in a "clean" environment but display reduced macrophage function in response to pathogens. Specifically, macrophages show impaired production of antimicrobial products and reduced expression of MHC II antigens. There is also uncontrollable proliferation of splenocytes from homozygotes in response to mitogens and alloantigens and a reduced resting natural killer cell activity. | ||

| 009344 | B6.Cg-Tg(tetO-Ifng)184Pop/J | Cryopreserved - Ready for recovery |
| The donating investigator reports that homozygous mice are viable and fertile. These TRE/IFN-γ transgenic mice have expression of mouse interferon-gamma (IFN-γ) regulated by the tetracycline-responsive promoter (tetO [also called tetracycline-responsive element (TRE or tet-operator)] fused to the human cytomegalovirus minimal promoter). When mated to a mutant strain expressing reverse tetracycline-controlled transactivator protein (rtTA) or tetracycline-controlled transactivator protein (tTA), expression of IFN-γ may be regulated with the tetracycline analog doxycycline (dox) in the double mutant offspring. Because interferon-gamma (IFN-γ) is a pleiotropic cytokine secreted by activated T-lymphocytes and natural killer cells, these line 184 TRE/IFN-γ mice may be bred to generate bi-transgenic mutant mice with conditional (inducible/reversible) expression of IFN-γ for studying antiviral responses, immune surveillance, inhibiting cellular prol .....

| 008228 | C3.129S7(B6)-Ifngtm1Ts/J | Cryopreserved - Ready for recovery |
| Leukocytes do not respond to and Th1 cells are not activated by skin grafts in homozygous mice. Homozygotes are resistant to experimentally induced alopecia areata with diminished T cell infiltration in skin and reduced MHC class I and II molecule expression in the hair follicle infrainfundibular site. No gene product (protein) is detected by ELISA analysis of splenocyte supernatants from homozygous animals. Mice that are homozygous for the targeted mutation are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. This mutant mouse strain may be useful in studies of immune response, inflammation and autoimmunity. | ||
| 002575 | NOD.129S7(B6)-Ifngtm1Ts/DvsJ | Cryopreserved - Ready for recovery |
| Mice homozygous for the Ifngtm1Ts targeted mutation are viable and fertile. This Ifng -deficient mutant develops type 1 diabetes at the same rate as the NOD/ShiLt parental strain. | ||
