Objective: The interleukin-12/interferon-γ (IL-12/IFN-γ) pathway is the most validated cytokine regulating Mycobacterium tuberculosis infection. role of IL-12/IFN-γ axis in protecting against (TB) exhibited people having mutations genes encoding these cytokines. We aimed to study serum levels IL-12 and IFN-γ pediatric their correlation with clinical microbiological features. Material Methods: A...

Previous studies have shown the central role of interleukin 12 (IL-12) in the development of resistance to Leishmania major infection in C3H mice. We now show that during the innate immune response the lymph node cells of L. major-infected C3H mice upregulate the IL-12 receptor on CD4(+), CD8(+), and B220(+) cells. An increase in the ability of the lymph node cells to bind IL-12 correlates with...
