RT Journal Article SR Electronic T1 T-cell cytokine responses in human infection with Mycobacterium tuberculosis. JF Infection and Immunity JO Infect. Immun. FD American Society for Microbiology SP 3231 OP 3234 VO 63 IS 8 A1 Zhang, M A1 Lin, Y A1 Iyer, D V A1 Gong, J A1 Abrams, J S A1 Barnes, P F YR 1995 UL http://iai.asm.org/content/63/8/3231.abstract AB Compared with healthy tuberculin reactors, Mycobacterium tuberculosis-stimulated peripheral blood mononuclear cells from tuberculosis patients had diminished production and mRNA expression of the Th1 cytokines gamma interferon and interleukin 2 (IL-2), with no change in production and mRNA expression for the Th2 cytokines IL-4, IL-10, and IL-13. These results were confirmed by evaluation of T cells and CD4+ cells. At the level of systemic T cells, development of tuberculosis is associated with diminished Th1 but not enhanced Th2 responses.
