Figure 1.

Phenotypic delineation of tissue-resident natural killer (trNK) cell subsets. Both human and mouse NK cells are shown. The surface markers of cNK cells from human blood or mice spleen are compared to the trNK cells from indicated tissues. (A) Conventional NK cells (cNK) are compared to lymph node (LN) and thymic NK cells. (B) Phenotypic markers of tissue-resident NK cells from the liver, lung, and uterus in humans and mice. CD56 is depicted in either bright green or light green to indicate the predominant presence of CD56^bright or CD56^dim subsets in the circulating conventional (cNK cells) or individual organs.
