doi: 10.1371/journal.pone.0342756

Figure Lengend Snippet: (A) Immunohistochemical staining of γH2AX, cGAS, STING, IRF3, and IFN-α was evaluated across multiple TMA slides and categorized as weak (1+), moderate (2+), or strong (3+). (B) Distribution of H-scores for each antibody across 164 cases. H-scores were categorized into two groups: Weak (0–150), Moderate to high (151–300). The Mann–Whitney U test was performed to compare two groups, *p < 0.001. Represents images acquired at 20 × magnification.

Article Title: IRF1 amplifies HSV-1-triggered antiviral innate immunity in a feed-forward manner

doi: 10.1016/j.cellin.2025.100255

Figure Lengend Snippet: IRF1 interacts with IRF3 and promotes IRF3 recruitment to ISG promoters . (A) THP-1 cells transduced with control sgRNA (Ctrl) or sgRNA targeting IRF1 were mock-infected or infected with HSV-1 (MOI = 5), and WCLs were analyzed by immunoblotting at 8 h post-infection. (B) THP-1 cells were mock-infected or infected with HSV-1 (MOI = 5), and nuclear and cytoplasmic fractions were isolated at the indicated time points and analyzed by immunoblotting. (C) HEK293T cells were transfected with the indicated plasmids, and WCLs were collected for immunoprecipitation with anti-FLAG affinity agarose. The input and precipitated samples were analyzed by immunoblotting. (D) HT1080 cells were infected with HSV-1 (MOI = 10) for 8 h. Co-immunoprecipitation was performed with the indicated antibodies, followed by immunoblotting analysis. (E) THP-1 cells transduced with control sgRNA (Ctrl) or sgRNA targeting IRF1 were mock-infected or infected with HSV-1 (MOI = 10), and nuclear and cytoplasmic fractions were isolated at 8 h post-infection and analyzed by immunoblotting. (F) THP-1 cells were mock-infected or infected with HSV-1 (MOI = 10) for 5 or 10 h. Cell lysates were collected and pulldown assays were performed using a biotin-labeled ISG54 ISRE probe. The input and probe-bound proteins were analyzed with the indicated antibodies. (G) THP-1 cells transduced with control sgRNA (Ctrl) or sgRNA targeting IRF1 were mock-infected or infected with HSV-1 (MOI = 10) for 8 h.
