Abstract

Riboswitches are 5' RNA regulatory elements that are capable of binding to various ligands, such as small metabolites, ions and tRNAs, leading to conformational changes and affecting gene transcription or translation. They are widespread in bacteria and frequently control genes that are essential for the survival or virulence of major pathogens. As a result, they represent promising targets for the development of new antimicrobial treatments. Clostridioides difficile, a leading cause of antibiotic-associated nosocomial diarrhoea in adults, possesses numerous riboswitches in its genome. Accumulating knowledge of riboswitch-based regulatory mechanisms provides insights into the potential therapeutic targets for treating C. difficile infections. This review offers an in-depth examination of the current state of knowledge regarding riboswitch-mediated regulation in C. difficile, highlighting their importance in bacterial adaptability and pathogenicity. Particular attention is given to the ligand specificity and function of known riboswitches in this bacterium. The review also discusses the recent progress that has been made in the development of riboswitch-targeting compounds as potential treatments for C. difficile infections. Future research directions are proposed, emphasizing the need for detailed structural and functional analyses of riboswitches to fully harness their regulatory capabilities for developing new antimicrobial strategies.

艰难梭菌目前的核糖开关状况。
核糖开关是 5' RNA 调控元件,能够与各种配体(如小代谢物、离子和 tRNA)结合,导致构象变化并影响基因转录或翻译。它们广泛存在于细菌中,经常控制对主要病原体的生存或毒力至关重要的基因。因此,它们是开发新型抗菌疗法的有希望的目标。难辨梭状芽孢杆菌是引起成人抗生素相关性院内腹泻的主要病原体,它的基因组中有许多核糖开关。对基于核糖开关的调控机制不断积累的知识为治疗艰难梭菌感染的潜在治疗靶点提供了启示。本综述深入探讨了艰难梭菌中核糖开关介导的调控机制的知识现状,强调了它们在细菌适应性和致病性方面的重要性。其中特别关注了该细菌中已知核糖开关的配体特异性和功能。综述还讨论了最近在开发核糖开关靶向化合物作为艰难梭菌感染的潜在治疗方法方面取得的进展。文章提出了未来的研究方向,强调需要对核糖开关进行详细的结构和功能分析,以充分利用其调控能力来开发新的抗菌策略。
