细胞外囊泡是大多数哺乳动物细胞和细菌自然释放的囊性囊泡。EV的含量包括蛋白质、脂质和核酸。电动汽车可以作为信使将多种分子传递给受体细胞,从而在细胞间信号转导中发挥重要的调节作用。由宿主细胞或病原体释放的ev可携带病原体相关抗原,因此可作为免疫反应的调节剂。来自结核分枝杆菌(Mtb)感染细胞的ev可以通过多种途径调节先天免疫反应,如调节炎症细胞因子的释放。此外,ev通过向T辅助细胞传递免疫调节分子介导抗原呈递和调节适应性免疫反应。本文就EVs在Mtb免疫应答中的调控作用作一综述。
Extracellular vesicles (EVs) are cystic vesicles naturally released by most mammalian cells and bacteria. EV contents include proteins, lipids, and nucleic acids. EVs can act as messengers to transmit a variety of molecules to recipient cells and thus play important regulatory roles in intercellular signal transduction. EVs, released by either a host cell or a pathogen, can carry pathogen-associated antigens and thus act as modulators of immune responses. EVs derived from Mycobacterium tuberculosis (Mtb)-infected cells can regulate the innate immune response through various pathways, such as regulating the release of inflammatory cytokines. In addition, EVs can mediate antigen presentation and regulate the adaptive immune response by transmitting immunoregulatory molecules to T helper cells. In this review, we summarize the regulatory roles of EVs in the immune response against Mtb.
