    Tuberculosis (TB) is a major health problem requiring an appropriate cell immune response (IR) to be controlled. Since regulatory T cells (Tregs) are relevant in IR regulation, we analyzed Tregs variations throughout the course of TB treatment and its relationship with changes in immune-endocrine mediators dealing with disease immunopathology. The cohort was composed of 41 adult patients, 20 of them completing treatment and follow-up. Patients were bled at diagnosis (T0) and at 2 (T2), 4 (T4), 6 (T6), and 9 months following treatment initiation. Twenty-four age- and sex-matched healthy controls (HCo) were also included. Tregs (flow cytometry) from TB patients were increased at T0 (versus HCo < 0.05), showing even higher values at T2 (versus T0 < 0.01) and T4 (versus T0 < 0.001). While IL-6, IFN-, TGF- (ELISA), and Cortisol (electrochemiluminescence, EQ) were augmented, DHEA-S (EQ) levels were diminished at T0 with respect to HCo, with cytokines and Cortisol returning to normal values at T9. Tregs correlated positively with IFN- ( = 0.868, < 0.05) at T2 and negatively at T4 ( = −0.795, < 0.05). Lowered levels of proinflammatory cytokines together with an increased frequency of Tregs of patients undergoing specific treatment might reflect a downmodulatory effect of these cells on the accompanying inflammation.Fil: Díaz, Ariana.

    TGF-β neutralization abrogates the inhibited DHEA production mediated by factors released from M. tuberculosis-stimulated PBMC

    Supernatants (SN) from cultures of peripheral blood mononuclear cells (PBMC) of tuberculosis (TB) patients inhibit dehydroepiandrosterone (DHEA) secretion by the adrenal cell line NCI-H295R. To analyze whether TGF-β is involved in this effect, SN of PBMC from healthy controls or patients with severe TB infections, stimulated or not with Mycobacterium tuberculosis (Mtb SN), were added to adrenal cells under basal conditions or following stimulation with forskolin. Cortisol and DHEA concentrations were evaluated in supernatants of the adrenal cells cultured with or without the addition of anti-TGF-β. Treatment with Mtb SN from TB inhibited DHEA production, and this effect was reversed when SN were treated with anti-TGF-β. The increase in cortisol production induced by SN from TB patients was not affected by TGF-β neutralization. Mediators released during the anti-TB immune response differentially modulate steroid production by adrenal cells, and TGF-β is a cytokine implicated in the inhibition of DHEA production observed in TB.Fil: D'attilio, Luciano David.
