Especially, it has been reported that miR-146a-5p could inhibit the proliferation and function (IL-13 secretion) of type II innate lymphoid cells (ILC2), efficiently protect mice against OVA-induced allergic asthma [34, 35], and also modulate anti-fibrosis responses induced by TGF-β1-Smad signaling [36]. Here, TGFB1 is linked to allergic asthma.
