    Effects of air pollutants on innate immunity: The role of Toll-like receptors and nucleotide-binding oligomerization domain–like receptors

    No full text
    Interactions between exposure to ambient air pollutants and respiratory pathogens have been shown to modify respiratory immune responses. Emerging data suggest key roles for Toll-like receptor (TLR) and nucleotide-binding oligomerization domain–like receptor (NLR) signaling in pathogen-induced immune responses. Similarly, immune responses elicited by exposure to air pollutants are mediated by specific TLR- and NLR-dependent mechanisms. This review article will summarize current knowledge about how air pollutants modify TLR- and NLR-dependent signaling and host defense responses in the lung
