- Abstract
The effect of cortisol and/or dehydroepiandrosterone (DHEA) on the immune response to antigens obtained fromMycobacterium tuberculosiswas studiedin vitroby using peripheral blood mononuclear cells obtained from patients at various stages of lung tuberculosis (TB) and from healthy control people (HCo). The results obtained show for the first time that addition of cortisol within concentrations of physiological range can inhibit the mycobacterial antigen-driven proliferation of cells from HCo and TB patients and the production of interferon-γ (IFN-γ), indicating that endogenous levels of cortisol may contribute to the decreased lymphoid cell response to mycobacterium antigens observed in TB patients. DHEA did not affect lymphoid cell proliferation, IFN-γ production and the cortisol-mediated inhibitory effects. Interestingly, we found that DHEA, but not cortisol, suppressed thein vitrotransforming growth factor-β production by lymphoid cells from TB patients with an advanced disease, which is indicative of a selective direct effect of this hormone.
