Tuberculosis is a lethal disease that is one of the world's top ten death-associated infections in humans; causes tuberculosis, and this bacterium is linked to the lysis of autophagolysosomal fusion action, a self-defense mechanism of its own. Thus, Cytoplasmic bacilli are sequestered by autophagy and transported to lysosomes to be inactivated to destroy intracellular bacteria. Besides this, a macrophage can limit intracellular Mycobacterium by using a type of autophagy, selective autophagy, a cell that marks undesirable ubiquitin existence in cytosolic cargo, acting as a "eat me" sensor in conjunction with cellular homeostasis. genes of the protein family inhibit autophagy, increase mycobacterial survival, and lead to latent tuberculosis infection associated with miRNAs. In addition, the family of autophagy-regulated (ATG) gene members are involved in autophagy and controls the initiation, expansion, maturation, and fusion of autophagosomes with lysosomes, among other signaling events that control autophagy flux and reduce inflammatory responses and forward to promote cellular proliferation. In line with the formation of caseous necrosis in macrophages by and their action on the lysis of autophagosome fusion, it leads to latent tuberculosis infection. Therefore, we aimed to comprehensively analyses the autophagy and self-defense mechanism of , which is to be gratified future research on novel therapeutic tools and diagnostic markers against tuberculosis.
结核病是一种致命疾病,是全球人类十大死亡相关感染之一;结核杆菌引发结核病,这种细菌与自噬溶酶体融合作用的裂解相关,自噬溶酶体融合作用是机体自身的一种自我防御机制。因此,胞质内的杆菌通过自噬被隔离并转运至溶酶体,从而失活以杀灭胞内细菌。除此之外,巨噬细胞可通过一种自噬方式,即选择性自噬来限制胞内分枝杆菌,选择性自噬是一种标记胞质货物中存在不良泛素的细胞,与细胞稳态一起充当“吃我”传感器。蛋白质家族的基因抑制自噬,增加分枝杆菌的存活,并导致与微小RNA相关的潜伏性结核感染。此外,自噬调节(ATG)基因家族成员参与自噬,并控制自噬体与溶酶体的起始、扩张、成熟和融合,以及控制自噬通量、减少炎症反应并促进细胞增殖的其他信号事件。与结核杆菌在巨噬细胞中形成干酪样坏死及其对自噬体融合裂解的作用一致,这会导致潜伏性结核感染。因此,我们旨在全面分析结核杆菌的自噬和自我防御机制,这有望为未来针对结核病的新型治疗工具和诊断标志物的研究带来成果。
