Other studies have reported that miR-155-5p dysregulates intestinal epithelial Zo-1 by targeting RhoA. In addition, miR-155-5p regulates Th2 cytokines by inhibiting the expression of the PU.1 in the lung. In this study, upregulation of miR-155-5p directly targeting PKIα, which induces the disruption of TJ proteins, and then increases the expression of initiative key factors (TSLP, IL-33), promoted the release of type 2 cytokines and aggravated the allergic inflammation.
