doi: 10.1128/mbio.02687-22
Figure Lengend Snippet: UBXN3B restricted CHIKV infection in an IFN-I-independent manner. (A and B) Bone marrow-derived mouse dendritic cells were infected with CHIKV/ZIKV at a multiplicity of infection (MOI) of 1. Quantitative RT-PCR (qPCR) quantification of (A) viral RNA and (B) immune gene mRNA. Each symbol is one mouse. The small horizontal line is the median of the result. (C) Viral titers (PFU/mL) in the supernatants of mouse embryonic fibroblast (MEFs) infected with CHIKV (MOI = 0.5). Bar, mean ± SEM (N = 3). qPCR quantification of (D) ISG mRNA and (E) CHIKV RNA. MEFs were treated with an anti-IFNAR1 antibody or control IgG (8 μg/mL) for 2 h and then infected with CHIKV (MOI = 0.5) in the presence of antibodies for 24 h (N = 6 biological repeats). *, P < 0.05; **, P < 0.01 (two-tailed Student's t test). The results are representative of 3 independent experiments.
Article Snippet: The goat anti-mouse IFNAR1 (number AF30369) was purchased from R&D Systems (Minneapolis, MN 55413, USA), rabbit anti-GAPDH (Clone D16H11, number 5174), anti-β-Actin (Clone 13E5, number 4970) and STING (Clone D2P2F, number 13647) were from Cell Signaling Technology (Danvers, MA, USA).
