Abstract

It has long been recognized that human NK cells can be divided into two phenotypically and functionally distinct subsets, based on their levels of expression of CD56. We recently found that CD27 distinguishes subsets of mature mouse NK cells. Here we report that CD27 can be used as a marker to discriminate human NK cell subsets. The majority of peripheral blood human NK cells were CD27(lo)/CD56(dim) NK cells, whereas the minor CD27(hi) NK cell population correspondingly displayed a CD56(bright) phenotype. Distinctions between CD27(lo) and CD27(hi) NK cells in their receptor expression and typical NK cell functions such as cytotoxicity and cytokine production can be easily delineated. Therefo..
