Figure Lengend Snippet: HTATSF1 is important for HSV-1- or SeV-triggered phosphorylation of downstream signaling components. (A) Effects of HTATSF1-deficiency on HSV-1- or SeV-induced phosphorylation of TBK1, IRF3, and STAT1 in THP-1 cells. The control (g NC ) and HTATSF1-deficient (g HTATSF1 ) THP-1 cells (1 × 10 6 ) were left uninfected or infected with HSV-1 (MOI = 1) or SeV (MOI = 1) for the indicated times before immunoblotting analysis with the indicated antibodies. (B) Effects of HTATSF1-deficiency on HSV-1- or SeV-induced phosphorylation of TBK1, IRF3, and STAT1 in BMDMs. Lyz2 -Cre; Htatsf1 fl/fl and Htatsf1 fl/fl BMDM cells (1 × 10 6 ) were left uninfected or infected with HSV-1 (MOI = 1) or SeV (MOI = 1) for the indicated times before immunoblotting analysis with the indicated antibodies.
