The neurodegeneration and its related CNS pathologies need an urgent toolbox to minimize the global mental health burden. The neuroimmune system critically regulates the brain maturation and survival of neurons across the nervous system. The chronic manipulated immunological drive can accelerate the neuronal pathology hence promoting the burden of neurodegenerative disorders. The gut is home for trillions of microorganisms having a mutual relationship with the host system. The gut-brain axis is a unique biochemical pathway through which the gut residing microbes connects with the brain cells and regulates various physiological and pathological cascades. The gut microbiota and CNS communicate using a common language that synchronizes the tuning of immune cells. The intestinal gut microbial community has a profound role in the maturation of the immune system as well as the development of the nervous system. We have critically summarised the clinical and preclinical reports from the past a decade emphasising that the significant changes in gut microbiota can enhance the host susceptibility towards neurodegenerative disorders. In this review, we have discussed how the gut microbiota-mediated immune response inclines the host physiology towards neurodegeneration and indicated the gut microbiota as a potential future candidate for the management of neurodegenerative disorders.
神经退行性变及其相关的中枢神经系统疾病需要一个紧急的工具箱,以最大限度地减少全球精神健康负担。神经免疫系统对整个神经系统中大脑的成熟和神经元的存活起着至关重要的调节作用。慢性操纵的免疫驱动可以加速神经元病理学,从而加重神经退行性疾病的负担。肠道是数万亿微生物的家园,它们与宿主系统有着相互的关系。肠-脑轴是一种独特的生化途径,通过该途径,肠道内的微生物与脑细胞相连,并调节各种生理和病理级联反应。肠道微生物群和中枢神经系统使用共同的语言进行交流,从而同步调节免疫细胞的功能。肠道肠道微生物群落在免疫系统的成熟以及神经系统的发育中起着重要的作用。我们对过去十年的临床前和临床报告进行了批判性总结,强调肠道微生物群的显著变化会增加宿主对神经退行性疾病的易感性。在这篇综述中,我们讨论了肠道微生物群介导的免疫反应如何使宿主生理学倾向于神经退行性变,并指出肠道微生物群是神经退行性疾病管理的潜在未来候选者。
