During the differentiation of naive CD4(+) T cells isolated from T cell receptor transgenic mice , GATA-3 gene expression was up-regulated in developing Th2 cells , but was down-regulated in Th1 cells , and antigen- or cAMP-activated Th2 cells (but not Th1 cells ) expressed the GATA-3 protein .
 ( cell type: Th2 cells, None) , ( protein: GATA-3, None) , ( cell type: Th1 cells, None) , ( cell type: naive CD4(+) T cells, None) , ( cell type: antigen- or cAMP-activated Th2 cells, None) , ( protein: GATA-3 protein, None) , ( cell type: Th2 cells, None) , ( protein: GATA-3, None) , ( cell type: Th1 cells, None)
