In recent years, scientists studying the molecular mechanisms of inflammation have discovered an amazing phenomenon - the inflammasome - a component of the innate immune system that can regulate the functional activity of effector cells during inflammation. At present, it is known that inflammasomes are multimolecular complexes (cytosolic multiprotein oligomers of the innate immune system) that contain many copies of receptors recognizing the molecular structures of cell-damaging factors and pathogenic agents. Inflammasomes are mainly formed in myeloid cells, and their main function is participation in the cleavage of the pro-IL-1β and pro-IL-18 cytokines into their biologically active forms (IL-1β, IL-18). Each type of microorganism influences particular inflammasome activation, and long-term exposure of the organism to viruses, bacteria, yeasts or parasites, among others, can induce uncontrolled inflammation and autoinflammatory diseases. Therefore, this review aims to present the most current scientific data on the molecular interplay between inflammasomes and particular microorganisms. Knowledge about the mechanisms responsible for the interaction between the host and certain types of microorganisms could contribute to the individuation of innovative strategies for the treatment of uncontrolled inflammation targeting a specific type of inflammasome activated by a specific type of pathogen.
近年来,研究炎症分子机制的科学家们发现了一个惊人的现象——炎症小体,这是先天免疫系统的一个组成部分,能够在炎症期间调节效应细胞的功能活性。目前已知,炎症小体是多分子复合物(先天免疫系统的细胞溶质多蛋白寡聚体),其中包含许多识别细胞损伤因子和病原体分子结构的受体拷贝。炎症小体主要在髓样细胞中形成,其主要功能是参与将前 IL-1β 和前 IL-18 细胞因子切割成其生物活性形式(IL-1β、IL-18)。每种类型的微生物都会影响特定的炎症小体激活,而机体长期暴露于病毒、细菌、酵母或寄生虫等微生物中会导致失控性炎症和自身炎症性疾病。因此,本综述旨在介绍炎症小体与特定微生物之间分子相互作用的最新科学数据。了解宿主与某些类型的微生物相互作用的机制,有助于确定针对由特定病原体激活的特定类型炎症小体的、治疗失控性炎症的创新策略。
