Expression of CD69 and CD71 by B-CLL cells from unmutated and mutated cases.

PBMCs from 61 B-CLL cases were analyzed specifically for the expression of CD69 and CD71 on CD5⁺CD19⁺ cells. The percentages of CD5⁺CD19⁺ cells expressing CD69 or CD71 were plotted independently in each of the 2 adjacent scattergrams. The symbol representing the percentage of cells expressing CD69 is connected with a line to the symbol representing the percentage of cells expressing CD71 in each individual unmutated (left panel) and mutated case (right panel). Overall, the percentages of cells expressing CD69 inversely correlated with those expressing CD71 (P < .001).
