In LTBI participants and pre-XDR/XDR-TB patients, mo-DCs matured with ECAT peptide pool and cocktail (ECAT + C), PE/PPE peptide pool and cocktail (PE/PPE + C), or HN878 lysate and cocktail (HN878 + C) expressed higher levels of CCR7, CD80, CD83, and CD86 compared to mo-DCs matured with ECAT peptide pool only (ECAT only), PE/PPE peptide pool only (PE/PPE only), and HN878 lysate only (HN878 only; p ≤ 0.02 for all comparisons in LTBI; p ≤ 0.003 for all comparisons in pre-XDR/XDR; Figure 3A–D and Figure A4). Here, CD80 is linked to tuberculosis.
