Abstract

Bacterial infections pose a significant risk to global health, with virulence factors playing a crucial role in the development of diseases. Metalloproteases have been recognised as essential enzymes that selectively interact with and degrade vital components of the host, thus increasing vulnerability to infections. They promote breakdown of extracellular matrix proteins, including collagen, fibrin, and laminin, thereby undermining structural integrity and facilitating tissue penetration and establishment of infection. In addition to structural damage, metalloproteases interfere with immunoglobulins, antimicrobial peptides, and complement proteins, aiding pathogens in evading the host's immune responses. To combat bacterial infections and the growing issue of antibiotic resistance, developing advanced treatments requires understanding those enzymes. By providing a comprehensive analysis of the mechanisms by which bacterial metalloproteases facilitate host-pathogen interactions, this review explores current and potential therapeutic strategies, including targeted inhibitors. For therapeutic applications, understanding virulence and immune evasion allows researchers to target bacterial metalloproteases more effectively.

宿主-病原体相互作用中的细菌金属蛋白酶。
细菌感染对全球健康构成重大风险,毒力因素在疾病的发展中起着至关重要的作用。金属蛋白酶已被认为是选择性地与宿主的重要成分相互作用和降解的基本酶,从而增加了对感染的脆弱性。它们促进细胞外基质蛋白的分解,包括胶原蛋白、纤维蛋白和层粘连蛋白,从而破坏结构完整性,促进组织渗透和感染的建立。除了破坏结构外,金属蛋白酶还会干扰免疫球蛋白、抗菌肽和补体蛋白,帮助病原体逃避宿主的免疫反应。为了对抗细菌感染和日益严重的抗生素耐药性问题,开发先进的治疗方法需要了解这些酶。通过全面分析细菌金属蛋白酶促进宿主-病原体相互作用的机制,本综述探讨了当前和潜在的治疗策略,包括靶向抑制剂。对于治疗应用,了解毒性和免疫逃避使研究人员能够更有效地靶向细菌金属蛋白酶。图形化的简介:
