In a previous report using an acute murine asthma model, we demonstrated that FUT and FOY inhibited antigen-induced airway eosinophilia, IgE production, and IL-4 and TNF-α levels and augmented IL-12 levels, a critical Th1 cytokine, in bronchoalveolar lavage fluid (BALF); however, UTI had no effect [12]. Here, IL4 is linked to bacterial urinary tract infection.
