In this study, following intranasal infection with RSV, BALB/c mice showed a marked increase in the production of IL-33, with an elevated expression of ST2 mRNA as well as a massive infiltration of CD45(+) ST2(+) cells in the lungs, suggesting that during the early phase of RSV infection, IL-33 target cells which express ST2 on cell surface, may play a critical role for the development of RSV-induced airway inflammation.
