ELISA assay revealed consistent results with the qRT-PCR assay, suggesting that dTHP1 cells secreted large amounts of proinflammatory cytokines (IL-6, IL-1β, and TNF-α) and chemokine MCP-1 into the supernatant during the infection process (p < 0.05) (Figure 7C). This evidence concerns the gene CCL2 and infection.
