Deletion of the A52R, B15R, and K7R genes affects cytokine/chemokine levels. Shown are concentrations of cytokine IL-6 (A) and chemokines CXCL1 (B), CXCL2 (C), CCL2 (D), CCL3 (E), CXCL10 (F), and CXCL9 (G) at 6 h postinfection in the peritoneal cavity of NYVAC-C- or NYVAC-C deletion mutant-injected mice. Graphs show the mean ± SEM; each point represents an individual mouse. Data are representative of two independent experiments. *, P < 0.05; **, P < 0.01; ***, P < 0.001.
