Abstract Although NK cells are considered innate, recent studies in mice revealed the existence of a unique lineage of hepatic CD49a+DX5− NK cells with adaptive-like features. Development of this NK cell lineage is, in contrast to conventional NK cells, dependent on T-bet but not Eomes. In this study, we describe the identification of a T-bet+Eomes−CD49a+ NK cell subset readily detectable in the human liver, but not in afferent or efferent hepatic venous or peripheral blood. Human intrahepatic CD49a+ NK cells express killer cell Ig-like receptor and NKG2C, indicative of having undergone clonal-like expansion, are CD56bright, and express low levels of CD16, CD57, and perforin. After stimulation, CD49a+ NK cells express high levels of inflammatory cytokines but degranulate poorly. CD49a+ NK cells retain their phenotype after expansion in long-term in vitro cultures. These results demonstrate the presence of a likely human counterpart of mouse intrahepatic NK cells with adaptive-like features.
