NK cell proliferation and inflammation.
Considerable progress has been made in recent years in understanding the biology of NK cells. NK cells are no longer 'null cells', but express an array of functionally important molecules with which they mediate and regulate their cytolytic activity and the cytokines they secrete. Activation and proliferation of NK cells in influenced by cytokines produced by activated monocytes (IL-15, IL-12, IL-10) and activated T cells (IL-2). This paper reviews the phenotype and effector functions of NK cells, their tissue distribution, and evidence that NK cells proliferate in vivo as part of productive or pathologic consequences of immunity.
