However, when the expression intensity of antigens was shown, we found that median level of CD117 (P = 0.002), CD13 (P < 0.001), CD35 (P < 0.001), CD64 (P < 0.001), and MPO (P < 0.001) in APL patients are significantly higher than in non-APL subjects (Fig. 1). Here, ANPEP is linked to acute promyelocytic leukemia.
