nfκb1^−/−CD8SP thymocytes acquire memory markers independently of IL-15. (A) CD4 and CD8 expression by thymocytes from 8-week-old il15^+/−, il15^−/−, nfκb1^−/− and nfkb1^−/− il15^−/− mice. Values represent percentages of cells in each quadrant. Expression of CD44 and CD122 by CD8SP thymocytes (lower dot plots) with numbers representing the percentages CD44^hiCD122^hi CD8SP cells. (B) Mean±s.e.m. (n=6 mice per genotype) number of CD8SP and CD44^hiCD122^hi CD8SP thymocytes. Data are representative of five experiments. P-values were determined by an unpaired two-tailed Student's t-test.
