Increased expression of wild-type NFAT1 substantially increases IL-4 promoter activity in unprimed CD4 T cells , suggesting NFAT1 may be limiting for IL-4 gene expression in this cell type.
 ( protein: IL-4, None) , ( protein: NFAT1, None) , ( protein: NFAT1, None) , ( protein: IL-4, None) , ( cell type: CD4 T cells, None) , ( DNA: IL-4 promoter, None)
