Stat 6 regulation of in vivo il-4 responses

WebAug 17, 2011 · Normal in vivo Th2 responses were observed in IL‐4‐ and STAT6‐deficient mice infected with N. brasiliensis suggesting that Th2 cells can differentiate independent of IL‐4–STAT‐6 signalling. 10, 56 Of note, GATA3 appears to be essential for in vitro and in vivo generation of Th2 cells. 50 WebSTAT6-deficient mice lack most of the physiologic functions associated with IL-4, in particular the ability of IL-4 to induce the in vitro differentiation of Th2 cells.25 STAT6 is critically involved in several distinct aspects of allergic inflammatory disease, like airway hyperresponsiveness, eosinophilic infiltration, and responses of mast cells.
