Abstract
Natural killer (NK) cells are immune effector cells that have long been known to possess potent cytotoxic ability. Despite this, NK cells remained relatively underrepresented in the medical literature, due in part to the strong emphasis placed on studying the mechanisms of the antigenic specificity and memory of T and B lymphocytes. Fortunately, as innate cells have gained prominence in recent years, NK cell research has blossomed and we now have a glimpse of the complexity of these cells and the potential that they have in cancer therapy. Not only do NK cells have a powerful ability to directly kill abnormal cells, they play a critical role in shaping adaptive responses by secreting a wide array of regulatory factors and interacting with multiple cell types. This chapter provides an overview of the current understanding of human NK cells, and discusses the potential of taking advantage of this knowledge to use NK cells in cancer therapy. Although much of our knowledge of NK cell biology comes from mouse studies, many of which involved models of viral or auto-immune diseases, the focus here is on observations made with human NK cells in the context of cancer.
