STAT6 and allergic asthma: Comparing STAT6-deficient mice (Figure 7C) and wild-type mice treated with a STAT5/6 small peptide inhibitor (PM-43I; Figure 7D) shown to reverse established allergic asthma after 4 weeks (10), we found that lack of STAT6 in both contexts suppressed or abrogated sinonasal inflammation, including the reduction of all major inflammatory cells, elicited by A. niger challenge.
