NK cells аnd ILCs cоntribute tо immune hоmeostаsis but cаn also drive pathology in chronic inflammation and autoimmune diseases. Your research team has identified a novel cytokine that enhances NK cell cytotoxicity. This cytokine increases perforin and granzyme production and promotes IFN-γ secretion. (A) Would this cytokine improve NK cell responses against viral infections such as cytomegalovirus (CMV)? Why or why not? (2 points) (B) Would this cytokine enhance NK cell-mediated immune surveillance against solid tumors? Justify your response based on NK cell function. (2 points) (C) Briefly describe one way in which ILCs contribute to tissue homeostasis and immune regulation. Be specific about the ILC subset, its cytokines, and its impact on tissue function. (2 points) (D) Briefly explain one mechanism in which dysregulated ILC activity may contribute to chronic inflammation. Be specific about the ILC subset, its cytokines, and its impact on tissue function. (2 points)
