We observed that Abs directed against unique domains of STAT6 have differential effects on complexes in T cells but not in NK cells , suggesting different STAT6 isoforms .
 ( protein: STAT6 isoforms, None) , ( protein: STAT6, None) , ( cell type: T cells, None) , ( protein: STAT6, None) , ( cell type: NK cells, None)
