Example of an inducible system available on available on BALB/c strain: Figure 1
The tGO transgene is a fusion protein made up of the cytoplasmic and TM domains of the transferring receptor and the immunogenic peptides of ovalbumin linked to a tetracycline regulated promoter. If these mice are bred to the Ii-rtTA transgenic line, and the resulting F1 offspring are fed doxycycline, the transgene is expressed in MHC class II+ cells. Expression of the transgene can be detected by injecting the mice with CSFE-labeled DO11 TCR transgenic T cells (reactive with valuing). CSFE is a fluorescent dye and the intensity of staining is diluted two fold every time a cell divides; this loss of fluorescence can be detected with a flow cytometer. Cell division and survival can be further monitored with the antibody KJ126 that reacts with the variable domains of the DO11 T cell receptor. As shown in the bottom panel of the figure, in doxycycline fed mice, the DO11 T cells undergo multiple divisions leading to a dramatic increase in cell number. The tGO mice can be bred to additional transgenic lines in which transactivator expression is regulated by an assortment of tissue specific promoters to establish model systems for the analysis of autoimmune disease. These studies were greatly facilitated by the ability of the Transgenic Core to inject the tGO construct directly into BALB/c oocytes. AMR07
