<i>Alternaria</i> Inhibits Double-stranded RNA-Induced Cytokines Productions through TLR3

Abstract

Background-Fungi may be involved in asthma and chronic rhinosinusitis (CRS). PBMCs from CRS patients produce IL-5, IL-13 and INF-γ by Alternaria. In addition, Alternaria produces potent Th2-like adjuvant effects in the airway. Therefore, we hypothesized that Alternaria may inhibit Th1-type defense mechanisms against virus infection.
