Microorganisms live in the human digestive system and the gut microbiome constitutes part of our prime determining component for healthy aging and wellness. Gut microbiota has broad influences on its host, beginning from the digestion of food and nutrients absorption to protective roles against invading pathogens and host immune system regulation. Dysbiosis of the gut microbial composition has been linked to numerous diseases and there is a need to have a better grasp on what makes a 'good' gut microbiome. ( ) model organism is considered as a well-suited model system and, is at the frontline of probiotic research because of its well-defined characteristics and prolific nature. Most importantly, feeds on bacteria, which speeds up manipulations and investigations in probiotics research tremendously. With its unique salient features of short lifespan, and ease of propagation, different unknown probiotics biological roles can be measured at an organism level with precision in the form of worm's stress responses, survivability, and lifespan. In this review, new insights on the different mechanisms underlying the establishment of probiotics regulations of conserved signalling pathways such as p38 MAPK/SKN-1, DAF-2/DAF-16, and JNK-1/DAF-16 is highlighted based on information obtained from studies. Along with the current state of knowledge and the uniqueness of as a model organism, explorations of its future contribution and scope in synthetic biology and probiotics engineering strains are also addressed. This is expected to strengthen our understanding of probiotics roles and to facilitate novel discovery and applications, for specific therapeutics against age-related disorders and various pathophysiological conditions.
微生物存在于人体消化系统中,肠道微生物群是我们健康衰老和保持健康的主要决定因素之一。肠道微生物群对其宿主有广泛影响,从食物消化和营养吸收到抵御入侵病原体的保护作用以及宿主免疫系统调节。肠道微生物组成的失调与多种疾病有关,因此有必要更好地了解什么构成了“良好的”肠道微生物群。( )模式生物被认为是一个非常合适的模型系统,由于其明确的特征和丰富的特性,处于益生菌研究的前沿。最重要的是,( )以细菌为食,这极大地加速了益生菌研究中的操作和调查。凭借其寿命短和易于繁殖的独特显著特征,可以以蠕虫的应激反应、生存能力和寿命的形式在生物体水平上精确测量不同未知益生菌的生物学作用。在这篇综述中,基于从( )研究中获得的信息,突出了对保守信号通路如p38 MAPK/SKN-1、DAF-2/DAF-16和JNK-1/DAF-16的益生菌调节建立的不同机制的新见解。连同当前的知识状态以及( )作为模式生物的独特性,还探讨了其在合成生物学和益生菌工程菌株方面未来的贡献和范围。这有望加强我们对益生菌作用的理解,并促进针对与年龄相关疾病和各种病理生理状况的特定治疗方法的新发现和应用。
