Tables 4, 5 showed that the level of IL-6 at 24~48 h and IL-10 at 4~48 h of MDR-MTB group were respectively lower than those of infection group after administration with Dlm, suggesting that Dlm might have immunosuppressive effect on IL-6 and IL-10, which could inhibit their secretion and expression so as to promote the formation of the immune response dominated by Th1 cell indirectly and the elimination of MDR-MTB. Here, IL10 is linked to infection.
