Kinetics of occurrence of NK-cell subsets after DT-induced depletion in NDE mice. (A) Representative flow cytometric analysis of CD27/CD11b expression by splenic NK cells over time after DT-induced depletion. (B) Frequency of each subset in NK cells of different organs, over time after DT-induced depletion, as calculated from flow cytometry data; n = 3 to 8 mice for each time point. (C) Frequency of each subset in splenic NK cells isolated from C57BL/6 mice of different ages; n = 3 or 4 for each time point.
