CXCL9 and infection: Because these results suggested that RVFV could interfere with immune response mRNA translation or protein synthesis, we next monitored using FACS assays the kinetic of expression of pro-inflammatory cytokines (CCL5, CXCL9, CXCL10, CXCL11, and IL-8) at different time points after astrocyte infection by different RVFV strains (Figure 6(B)).
