慢性淋巴细胞白血病中的单核/巨噬细胞研究进展

Research Advances of Monocyte/Macrophage in Chronic Lymphocytic Leukemia

慢性淋巴细胞白血病(chronic lymphocytic leukemia, CLL)作为一种疾病,其进展差异性较大,其中三分之二的患者发展缓慢,另三分之一患者疾病进展较快。常规治疗效果欠佳、常出现药物耐药。近年来研究发现,肿瘤微环境在CLL疾病进展中起到重要作用,单核/巨噬细胞(monocyte/macrophage)作为肿瘤微环境的组成部分,可以通过细胞间相互作用、分泌细胞因子、抑制机体抗肿瘤免疫反应等在CLL中发挥着促肿瘤细胞生长、促耐药等作用。因此,研究单核/巨噬细胞与CLL的关系,可为靶向治疗CLL提供理论依据。本文就单核/巨噬细胞在CLL疾病发展中的作用及相关治疗研究进展作一综述。

Chronic lymphocytic leukemia(CLL)is a malignant hematologic disease with heterogeneous clinical course, about two thirds of patients exhibit a long survival, but the remaining third of patients show aggressiveness of disease or poor response to conventional treatment even drug resistance. Studies suggested that tumor microenvironment possesses a critical effect in CLL disease progression in recent years. Monocyte/macrophage, as an important componens of tumor microenvironment, play a promotive role in the growth and drug reistance of tumor cells by direct cell-to-cell contact, secreting cytokines and suppressing antitumor responses. Therefore, exploring the monocyte/macrophage in CLL can provide theoretic basis for target treatment of CLL. In this review, the function of monocyte/macrophage and recent advances in therapy of CLL are discussed.
