Murine natural killer (NK) and natural cytotoxic (NC) cells showed different patterns of augmentation of lytic activity after preincubation for 24 h with either poly-IC, interleukin 2 (IL-2), or interleukin 3 (IL-3): (a) Poly-IC augmented only NK cells, with no effect on NC activity, as we have previously observed (4); (b) IL-2 augmented both NK and NC activity; and (c) IL-3 augmented only NC lysis, without affecting NK activity. In addition, both precursor and the augmented effector cells showed differences in expression of the Qa-5 surface marker: NK precursors and effectors are Qa 5+, whereas NC precursors and effector cells are Qa-5-.
将小鼠自然杀伤(NK)细胞和自然细胞毒性(NC)细胞分别与聚肌胞苷酸(poly-IC)、白细胞介素2(IL-2)或白细胞介素3(IL-3)预孵育24小时后,它们的溶解活性增强模式有所不同:(a)如我们之前观察到的(4),poly-IC仅增强NK细胞活性,对NC活性无影响;(b)IL-2增强NK和NC两者的活性;(c)IL-3仅增强NC细胞的裂解作用,而不影响NK细胞活性。此外,前体细胞和增强后的效应细胞在Qa-5表面标志物的表达上也存在差异:NK前体细胞和效应细胞为Qa 5+,而NC前体细胞和效应细胞为Qa-5-。
