CD69 and Hodgkins lymphoma: Fractions of T cells expressing the early activation marker CD69 were similar, whereas T cells expressing the late activation markers CD25 (16.2% ± 8.8 vs. 36.6% ± 8.8, p < 0.01) and CD62L (19.3% ± 11.9 vs. 39.8% ± 14.0, p < 0.01) were lower in patients with HL compared to healthy controls (Fig. 1B).
