IL13RA2 and inflammation: On the other hand, baseline levels of circulating soluble IL-13Rα2 were increased in HDM-challenged VSG mice when compared to Sham and NS group, suggesting that VSG elicits changes in Il13ra2 transcript processing that increase soluble IL-13Rα2 (63) or that changes in Il13ra2 expression occur in response to the development of airway inflammation.
