Effect of Ikaros deletion on gene expression in CD4 T cells

The goal of this experiment is to define how lack of Ikaros impacts gene expression in mature CD4 T cells, both in the resting and activated state. To do this, a conditional knockout mouse model was generated using Cre/lox technology. The floxed allele was designed such that the last translated exon and 3' UTR of the Ikaros gene (Ikzf1) are deleted in mature T cells (mediated by distal Lck-driven Cre). CD4 T cells from mice with floxed alleles that did not express Cre (Cre-) and those that did express Cre (Cre+) were analyzed.
