NO2dependentIL12PathwayinNKcells
Macrophages and NK cells help provide innate immunity against infection by intracellular parasites and communicate with each other to regulate this process. When stimulated, macrophages secrete the cytokine IL-12 that is essential for activation of the cytotoxic activity of natural killer (NK) cells. IL-12 stimulates this NK cell response through activation of a JAK/STAT signaling pathway. Binding of IL-12 to its rec......阅读全文
