A small, translucent nematode known as Caenorhabditis elegans, or C. elegans, is frequently utilized as a model organism in biomedical studies. These worms, which are around 1 mm long and feed on bacteria, are usually found in soil. For accessible and effective research on genetics, developmental biology, neuroscience, cell biology, and aging, C. elegans provide an ideal model. Its simplicity, which includes a translucent body and a nervous system with only 302 neurons, makes it possible to see cellular and developmental processes in great detail. Because of its special benefits, the worm Caenorhabditis elegans allows for a thorough characterization of the cellular and molecular processes causing age-related neurodegenerative diseases. This is a general review of the life cycle, experimental methodologies, and the use of C. elegans to model brain diseases, including those related to molecular and genetic factors that cause neurodegenerative diseases. Additionally, we go over how C. elegans is a perfect model organism for studying neurons in instances of prevalent age-related neurodegenerative illnesses due to a combination of its biological traits and new analytical techniques. The literature review process was carried out step-by-step using online search databases such as Web of Science, PubMED, Embase, Google Scholar, Medline, and Google Patents. In the first searches, keywords like C.elegans, disease modelling, and neuroprotective activity were employed. Because of C. elegans's physiological transparency, it is possible to track the development of neurodegeneration in aging organisms by using co-expressed fluorescent proteins. Importantly, a fully characterized connectome provides a unique ability to precisely connect cellular death with behavioural instability or phenotypic diversity in vivo, thus permitting a deep knowledge of the detrimental effect of neurodegeneration on wellbeing. In addition, pharmacological therapies and both forward and reverse gene screening speed up the discovery of modifiers that change neurodegeneration. These chemical-genetic investigations work together to determine important threshold states that either increase or decrease cellular stress in order to unravel related pathways.
一种名为秀丽隐杆线虫(Caenorhabditis elegans,简称C. elegans)的小型半透明线虫,经常被用作生物医学研究中的模式生物。这些线虫长约1毫米,以细菌为食,通常存在于土壤中。对于遗传学、发育生物学、神经科学、细胞生物学和衰老方面易于开展且有效的研究而言,秀丽隐杆线虫提供了一个理想的模型。它的简单性,包括半透明的身体和仅由302个神经元组成的神经系统,使得详细观察细胞和发育过程成为可能。由于其特殊优势,秀丽隐杆线虫能够全面表征导致与年龄相关的神经退行性疾病的细胞和分子过程。这是一篇关于秀丽隐杆线虫的生命周期、实验方法以及将其用于模拟脑部疾病(包括与导致神经退行性疾病的分子和遗传因素相关的疾病)的综述。此外,我们还探讨了由于秀丽隐杆线虫的生物学特性与新的分析技术相结合,它如何成为研究常见的与年龄相关的神经退行性疾病中神经元的完美模式生物。文献综述过程是通过使用诸如Web of Science、PubMED、Embase、Google Scholar、Medline和Google Patents这类在线搜索数据库逐步进行的。在首次搜索中,使用了诸如秀丽隐杆线虫、疾病建模和神经保护活性等关键词。由于秀丽隐杆线虫的生理透明性,通过使用共表达的荧光蛋白,可以追踪衰老生物体中神经退行性变的发展。重要的是,一个完全表征的连接体提供了一种独特的能力,能够在体内将细胞死亡与行为不稳定或表型多样性精确关联起来,从而深入了解神经退行性变对健康的有害影响。此外,药物治疗以及正向和反向基因筛选加速了对改变神经退行性变的调节因子的发现。这些化学遗传学研究共同作用以确定增加或减少细胞应激的重要阈值状态,从而揭示相关途径。
