In contrast, DOs responded to HCMV infection by secreting both proinflammatory cytokines and chemokines (e.g., CXCL10, MIP-1α, MIP-1β, and IL-6) and through the release of the type III IFN IFN-λ2 (Figure 8B, C and E, Figure 8—figure supplement 2B). This evidence concerns the gene CCL4 and cytomegalovirus infection.
