LLT1 cell surface expression was significantly higher in CD56+ NK cells isolated from the blood of ALL subjects at diagnosis and at the end of induction chemotherapy (34.50% and 36.18%, respectively) as compared to the expression in healthy (12.64%) subjects (p = 0.0035 and 0.0016, respectively; Figure 5). Here, CLEC2D is linked to acute lymphoblastic leukemia.
