In a series of electrophoretic mobility shift assays with protein extracts of highly polarized Th2 clones from atopics and Th1 clones from controls we compared DNA-binding activities at the two NFAT-binding elements P0 and P1 of the crucial proximal human IL-4 promoter .
 ( DNA: IL-4 promoter, None) , ( DNA: P0, None) , ( DNA: NFAT-binding elements, None) , ( cell line: highly polarized Th2 clones, None) , ( DNA: P1, None) , ( cell line: Th1 clones, None)
