The proportions of peripheral blood mononuclear cells (PBMC), CD4+ T cells, and CD8+ T cells that produce gamma interferon (IFN-γ) in response to Mycobacterium tuberculosis were markedly reduced in tuberculosis patients, particularly in those with severe disease. Depletion of CD4+ but not CD8+ cells prior to stimulation of PBMC with M. tuberculosis abolished IFN-γ production. These results show that (i) IFN-γ production by CD8+ and CD4+ cells correlates with the clinical manifestations of M. tuberculosis infection and (ii) IFN-γ production by CD8+ cells depends on CD4+ cells.
