Multiple myeloma is a hematologic malignancy characterized by growth of malignant plasma cells in the bone marrow. Tumor cells in myeloma express CD1d and are sensitive to lysis by CD1d restricted natural killer T (NKT) cells. Here we discuss recent studies to harness the properties of these cells in the context of human myeloma. In spite of large body of preclinical data, attempts to fully harness the properties of these cells in the clinic are in early stages. Early phase clinical studies document the capacity of human monocyte-derived dendritic cells to expand NKT cells in vivo in myeloma patients. These results have set the stage for ongoing studies combining NKT activation with immune-modulatory drugs. Lessons learnt from these studies may inform the optimal application of human NKT based therapies in other settings as well.
多发性骨髓瘤是一种血液系统恶性肿瘤,其特征是骨髓中恶性浆细胞的生长。骨髓瘤细胞表达 CD1d,并对 CD1d 限制的自然杀伤 T(NKT)细胞的溶解敏感。在这里,我们讨论了利用这些细胞在人类骨髓瘤中的特性的最新研究。尽管有大量的临床前数据,但在临床中充分利用这些细胞的特性的尝试仍处于早期阶段。早期的临床研究记录了人单核细胞衍生的树突状细胞在骨髓瘤患者体内体内扩增 NKT 细胞的能力。这些结果为正在进行的研究奠定了基础,即将 NKT 激活与免疫调节药物相结合。从这些研究中吸取的经验教训可能会为在其他情况下最佳应用基于人类 NKT 的治疗提供信息。
