IL10 and pulmonary tuberculosis: Methods: To investigate the role of anti-inflammatory cytokines in pulmonary TB (PTB), we investigated the plasma levels of Type 2 (IL-4, IL-5, IL-13), regulatory (IL-10, TGFb) and other anti-inflammatory (IL-19, IL-27, IL-37) cytokines in PTB, latent TB (LTB) or healthy control (HC) individuals.
