As IL-27 limits optimal antimycobacterial protection by inhibiting IL-17A production, blocking of IL-27R-mediated signaling may represent a strategy for improving vaccination and host-directed therapy in tuberculosis.
The concentration of interleukin-27 (IL-27) in pleural effusions was found to be increased in tuberculous pleurisy and several studies have investigated the diagnostic value of IL-27 for tuberculous pleural effusions (TPEs), but the results varied a lot.
Our results indicate that the genetic polymorphisms of IL-27rs153109 and rs181206 may be involved in the progression of human cancers and diseases, especially of TB, UC, COPD, OC, and ITP.
The significant expression of IL-27 in TB and the negative influence of IL-27R on T cell function demonstrate the pathway by which this cytokine/receptor pair is detrimental in TB.
These results implicate IL-12 and IL-27 in regulating human macrophages, and IL-27 derived from macrophages during infection impedes control of M. tuberculosis growth.
In this study we compared the effects of plasmids expressing both chains of IL-12, IL-23, or IL-27 as adjuvants for DNA immunization against M. tuberculosis infection.
