Clustered regularly interspaced short palindromic repeats (CRISPR)-Cas systems have gained attention for their revolutionary potential in tuberculosis (TB) management, providing a novel approach to both diagnostics and treatment. This technology, renowned for its ability to accurately target and modify genetic material, offers a promising solution to the limitations of current TB diagnostic methods, which often rely on time-consuming culture techniques or polymerase chain reaction (PCR)-based assays. One of the key advantages of CRISPR-Cas systems is their high specificity and sensitivity, making them well-suited for detecting , even in low-bacterial-load samples. Techniques such as CRISPR-Cas12 and Cas13 have been employed for rapid detection, utilizing their trans-cleavage activity to produce a fluorescent signal upon recognition of the TB genome. Furthermore, these methods often use isothermal amplification techniques like recombinase polymerase amplification (RPA) or loop-mediated isothermal amplification (LAMP), which require less equipment compared to traditional PCR. Beyond diagnostics, CRISPR-Cas technologies show promise in studying TB resistance mechanisms and potentially treating drug-resistant strains. Genome-editing capabilities enable researchers to manipulate the genome, investigating genes linked to virulence or antibiotic resistance. Although challenges such as the development of multiplexed CRISPR assays for detecting multiple mutations simultaneously remain, advancements continue to improve the technology's practicality for clinical use. Incorporating CRISPR into TB management could enhance early detection, inform personalized treatment, and potentially contribute to developing more effective therapies, especially in regions where TB remains a significant public health threat.
成簇规律间隔短回文重复序列(CRISPR)-Cas系统因其在结核病管理方面的革命性潜力而备受关注,为诊断和治疗提供了一种新方法。这项技术以其精确靶向和修饰遗传物质的能力而闻名,为当前结核病诊断方法的局限性提供了一个有前景的解决方案,当前方法通常依赖耗时的培养技术或基于聚合酶链反应(PCR)的检测方法。CRISPR-Cas系统的关键优势之一是其高特异性和敏感性,使其非常适合检测,即使在低细菌载量样本中也是如此。CRISPR-Cas12和Cas13等技术已被用于快速检测,利用它们的反式切割活性在识别结核基因组时产生荧光信号。此外,这些方法通常使用重组酶聚合酶扩增(RPA)或环介导等温扩增(LAMP)等等温扩增技术,与传统PCR相比,所需设备更少。除了诊断,CRISPR-Cas技术在研究结核病耐药机制和潜在治疗耐药菌株方面也显示出前景。基因组编辑能力使研究人员能够操纵基因组,研究与毒力或抗生素耐药性相关的基因。尽管同时检测多个突变的多重CRISPR检测方法的开发等挑战仍然存在,但进展继续提高该技术在临床应用中的实用性。将CRISPR纳入结核病管理可以加强早期检测,为个性化治疗提供依据,并可能有助于开发更有效的治疗方法,特别是在结核病仍然是重大公共卫生威胁的地区。
