Activation of TGF-beta by Leishmania chagasi: importance for parasite survival in macrophages.


TGF-beta is a potent regulatory cytokine that suppresses expression of inducible NO synthase and IFN-gamma, and suppresses Th1 and Th2 cell development. We examined whether functionally active TGF-beta is present in the local environment surrounding the invading protozoan Leishmania chagasi. Our prior data showed that TGF-beta levels are significantly… (More)
