Here we show that priming of CD4 T cells selectively enhances IL-4 expression relative to IL-2 expression by a transcriptional mechanism involving nuclear factor of activated T cells (NFAT) proteins .
 ( protein: nuclear factor of activated T cells, None) , ( protein: IL-2, None) , ( cell type: CD4 T cells, None) , ( protein: nuclear factor of activated T cells (NFAT) proteins, None) , ( protein: IL-4, None)
