tuberculosis -stimulated cell culture supernatants of individuals with HIV/PTB secreted significantly lower levels of TNF-α, IL-5, and IL-10 ( P < 0.05) and reduced levels of IL-13 (borderline significance; P = 0.13) than M. tuberculosis -stimulated cell culture supernatants of individuals with PTB ( Fig. 2C ).
