IL10 and tuberculosis: Fig 6A demonstrates high levels of cytokine mRNA in TB patients as compared to healthy controls. Despite the significant increase in the cytokine mRNA levels, there was no association between serum cytokine levels and monocyte mRNA level for either TNFα or IL10. Furthermore, there was no association between monocyte PDL1 level with mRNA for these cytokines despite relatively strong correlations of PDL1 with plasma cytokines Fig 6B–6E.
