Special Issues: Novel insights in NK cell receptors and their ligands in health and disease

The NK cells functions are finely tuned by several kinds of inhibitory and activating receptors, whose pattern of expression characterizes different NK subpopulations and varies with the cell activation status. MicroRNAs have an important role in tightly regulating the expression of NK receptors and, analogously, the expression of their ligands in target cells. The relevance of the microRNA-mediated control is highlighted by the dysregulation of these pathways observed in cancer and virus-infected cells. Here we review our current knowledge of the microRNAs involved in the regulation of NK receptors, as well as that of the corresponding cellular ligands.
