Immune cells in cancer

Natural killer (NK) cells are lymphocytes with important roles in innate and adaptive immune responses to tumours and viral infection. However, in certain chronic diseases, including obesity and cancer, NK cell functional responses are impaired. Recently, research has highlighted the importance of NK cell metabolism in facilitating robust NK cell effector functions. This Review describes our current understanding of mouse and human NK cell metabolism and the key signalling pathways that mediate metabolic responses in NK cells. Furthermore, it explores how defects in metabolism can contribute to the generation of dysfunctional NK cells in chronic disease. Finally, the potential for new therapeutic strategies targeting cellular metabolism is discussed.
