Immunosuppressive mediators in tuberculosis pleurisy (pleural fluid (PF)) are associated with the course of disease, but they remain poorly defined. To study the local immune status of patients with tuberculosis pleurisy, we examined the effect of PF on the functions of T cells and the differentiation of Th1 cells. PF could inhibit the ability of T cells to produce cytokines. However, tumor-necrosis factor (TNF)-α derived from non-T cells was not impaired. Further analysis indicated that cell activation and cell cycle progression were also suppressed. Moreover, PF could inhibit Th1 cell differentiation. Importantly, we found that inhibitors of indoleamine 2,3-dioxygenase (IDO) and adenosine and neutralizing antibodies against IL-10 and transforming growth factor (TGF)-β could reverse cytokine production, suggesting that IDO, adenosine, IL-10 and Transforming growth factor-β1 in PF might take part in impairing T-cell functions. Taken together, our data demonstrate for the first time that several immunopathological factors participate in the downregulation of T-cell functions in local PF.Cellular & Molecular Immunology advance online publication, 24 January 2011; doi:10.1038/cmi.2010.80.
