摘要:

外泌体是一种细胞分泌的胞外小囊泡,在细胞之间发挥着传递信息的作用,通过物质的转运来调节各种细胞的生理和病理功能。有研究表明,外泌体直接或通过中间细胞作用于恶性肿瘤细胞,进而在恶性肿瘤的发生、发展中发挥着重要作用。近年来,自然杀伤(natural killer,NK)细胞与肿瘤细胞源性外泌体(tumor-derived exosomes,TDEXs)的相互作用和调控机制成为研究热点。在肿瘤微环境中,TDEXs可以作用于NK细胞,改变NK细胞与其他免疫细胞和免疫因子的相互作用,最终导致NK细胞对恶性肿瘤细胞的免疫防御减弱和免疫耐受产生。该文综述了不同恶性肿瘤组织中TDEXs对NK细胞活性的影响和可能的机制。

Abstract:

Exosomes are a kind of extracellular vesicles that play the role of transmitting information among cells. Through transporting of substances to regulate the physiological and pathological functions of various cells, it can affect the progress of malignant tumors. Natural killer (NK) cell is an indispensable part of the human immune system, and is important in the development of cancers. In the tumor microenvironment, tumor-derived exosomes (TDEXs) can act on NK cells, adjusting their functions, and modifying the interaction between NK cells and other immune cells, resulting in the change of the immune response. In recent years, the research on the relationship between NK cells and tumor exosomes has become a hot topic. The effects of TDEXs from different cancers on the activities of NK cells are summarized in this paper.

Key words: malignant tumor, tumor-derived exosome, natural killer cell, activity
