Wnt5a, a prototype of a non-canonical Wnt signaling axis with known cross talk with TGFβ1 during repair and remodeling, was elevated in the airway epithelium of Th17 asthma patients and steroid-resistant asthma (Daud et al., 2016; Dietz et al., 2017). This evidence concerns the gene TGFB1 and asthma.
