In this study, we performed ENU mutagenesis and multi-parameter flow cytometric analysis in C57BL/6 mice to uncover novel genes or alleles regulating immune cell development. We identified a novel mutant allele ofCd4gene which completely blocked development of a major subset of T cells named CD4 T cell. Our data for the first time showed experimentally in mice the critical role of the first extracellular domain, by obtaining mice with a loss of function mutation from Ile to Asn at the position 99 of CD4 (I99N). Interestingly, such CD4I99Nmutant protein can be expressed on the surface of human cells, and the mRNA stability could be also affected by this point mutation, suggesting that absence of CD4 T cells in mice rooted in the deficiency in function and expression of CD4. In addition, we used this novel CD4 T cell deficient model as recipient mice for adoptive transfer experiment, and showed that it could be an optimal model for study of CD4 T cells.
