TSLP and bronchiolitis: It can be hypothesized that this stronger TSLP response after viral coinfection bronchiolitis, could stimulate a vigorous production of Th2-associated effector cytokines, such as IL-4, IL-5, IL-13, as was reported in asthmatic adults by Ying et al, that could be associated with higher frequency of wheezing and asthma development later on [31].
