NK cells and Treg cells: a fascinating dance cheek to cheek

Abstract

NK cells and Treg cells are both a major focus of current immunological interest. It is therefore not surprising that their interactions have been and continue to be investigated. New and challenging studies have been published in the past couple of years that confirm and extend previous knowledge in this area. In this Viewpoint, we will briefly review and comment on the recent literature regarding NK/Treg interactions.
