CCL4 and infection: On univariate analysis, myeloid inflammatory mediators including TNF, MIP-1α, MIP-1β, IL-10, IL-1α, IL-1RA, IFN-α2, and IP-10 were significantly higher in QFT+ 8-year-old children than in QFT- 8-year-old children (Figure 2D), suggesting that in vivo infection with M.tb, detected by QFT assay, can induce myeloid inflammatory responses.
