KLRG1 blockade causes a change in the expression of cell-cycle molecules. (A) Representative histograms of cyclin D2, cyclin E, and p27 flow cytometry in the CD8⁺ CD27/28 populations with or without the E-cadherin–blocking antibody. (B) Graphs showing the change in cyclin D2, cyclin E, and p27 phosphorylation levels in donors after E-cadherin blockade. Graphs show the mean ± SE for 3 donors. All P values were calculated using the Student t test.
