Tetraspanins, a wide family composed of 33 transmembrane proteins, are associated with different types of proteins through which they arbitrate important cellular processes such as fusion, adhesion, invasion, tissue differentiation and immunological responses. Tetraspanins share a comparable structural design, which consists of four hydrophobic transmembrane domains with cytoplasmic and extracellular loops. They cooperate with different proteins, including other tetraspanins, receptors or signalling proteins to compose functional complexes at the cell surface, designated tetraspanin‐enriched microdomains (TEM). Increasing evidences establish that tetraspanins are exploited by numerous intracellular pathogens as a doorway for entering and replicating within human cells. Although previous surveys focused mainly on viruses and parasites, it is now becoming clear that bacteria interact with tetraspanins, using TEM as a “gateway” to infection. In this review, we examine the biological functions of tetraspanins that are relevant to bacterial infective procedures and consider the available data that reveal how different bacteria benefit from host cell tetraspanins in infection and in the pathogenesis of diseases. We will also emphasise the stimulating potentials of targeting tetraspanins for preventing bacterial infectious diseases, using specific neutralising antibodies or anti‐adhesion peptide‐based therapies. Such innovative therapeutic opportunities may deliver alternatives for fighting difficult‐to‐manage and drug‐resistant bacterial pathogens.

四跨膜蛋白在细菌感染中的作用。

四跨膜蛋白是一个由 33 种跨膜蛋白组成的广泛家族,与不同类型的蛋白质相关,它们通过这些蛋白质调节重要的细胞过程,如融合、粘附、侵袭、组织分化和免疫反应。四跨膜蛋白具有类似的结构设计,由四个疏水性跨膜结构域和胞质环和胞外环组成。它们与不同的蛋白质合作,包括其他四跨膜蛋白、受体或信号蛋白,在细胞表面组成功能复合物,称为富含四跨膜蛋白的微区 (TEM)。越来越多的证据表明,四跨膜蛋白被许多细胞内病原体利用作为进入人体细胞并在其内复制的门户。虽然之前的调查主要集中在病毒和寄生虫上,现在越来越清楚的是,细菌与四跨膜蛋白相互作用,使用 TEM 作为感染的“门户”。在这篇综述中,我们检查了与细菌感染程序相关的四跨膜蛋白的生物学功能,并考虑了可用数据,这些数据揭示了不同细菌如何从宿主细胞四跨膜蛋白在感染和疾病发病机制中受益。我们还将强调使用特定的中和抗体或基于抗粘连肽的疗法,靶向四跨膜蛋白预防细菌感染性疾病的刺激潜力。这种创新的治疗机会可能为对抗难以控制和耐药的细菌病原体提供替代方案。我们检查了与细菌感染程序相关的四跨膜蛋白的生物学功能,并考虑了可用数据,这些数据揭示了不同细菌如何从宿主细胞四跨膜蛋白在感染和疾病发病机制中受益。我们还将强调使用特定的中和抗体或基于抗粘连肽的疗法,靶向四跨膜蛋白预防细菌感染性疾病的刺激潜力。这种创新的治疗机会可能为对抗难以管理和耐药的细菌病原体提供替代方案。我们检查了与细菌感染程序相关的四跨膜蛋白的生物学功能,并考虑了可用数据,这些数据揭示了不同细菌如何从宿主细胞四跨膜蛋白在感染和疾病发病机制中受益。我们还将强调使用特定的中和抗体或基于抗粘连肽的疗法,靶向四跨膜蛋白预防细菌感染性疾病的刺激潜力。这种创新的治疗机会可能为对抗难以管理和耐药的细菌病原体提供替代方案。我们还将强调使用特定的中和抗体或基于抗粘连肽的疗法,靶向四跨膜蛋白预防细菌感染性疾病的刺激潜力。这种创新的治疗机会可能为对抗难以管理和耐药的细菌病原体提供替代方案。我们还将强调使用特定的中和抗体或基于抗粘连肽的疗法,靶向四跨膜蛋白预防细菌感染性疾病的刺激潜力。这种创新的治疗机会可能为对抗难以管理和耐药的细菌病原体提供替代方案。
