Modulation of cellular tropism and innate antiviral response by viral glycans.
Arthropod-borne viruses (arboviruses) are a significant cause of human and animal disease worldwide. Multiple interactions between virus and the host innate immune system ultimately determine the pathogenesis and clinical outcome of the infection. Evidence is rapidly emerging that suggests viral glycans play a key role in viral pathogenesis by regulating host cell tropism and interactions with the host innate immune response. Glycan-mediated interactions are especially important for arboviruses which must adapt to variable glycosylation systems and cellular receptors within both vertebrate and invertebrate hosts. This review focuses on emerging evidence which supports a crucial role for viral glycans in mediating host cell tropism and regulating the innate antiviral response.
