Interestingly, infection with either of the three RNA viruses induced elevated levels of STING dimers in the lysates (Fig. 1f), and consistent with this, the residual induction of interferon-β and CXCL10 expression by IAV in MAVS-deficient cells was ablated when STING but not cGAS was knocked down by shRNA (Fig. 1g and Supplementary Fig. 2d). The gene discussed is CXCL10; the disease is infection.
