Elucidating the Role of Probiotics in Modulating Depression Pathophysiology: Insights from Animal Models and Clinical Trials-A Narrative Review

引用

Food Science and Human Wellness 2024年

作者： Sashuang Dong Fanyu Hao Bin Xue Sitong Wu Ruimin Zhong Zhenlin liao Hongying Han Xiang fang Guangdong Provincial Key Laboratory of Utilization and Conservation of Food and Medicinal Resources in Northern Region， Shaoguan University College of Food Science， South China Agricultural University Department of Psychiatry， The Third Affiliated Hospital of Sun Yat-Sen University

With the ongoing COVID-19， a significant increase in global depression rates has placed a considerable strain on healthcare systems. Conventional pharmaceutical methods have shown limitations in treating this rise in depression. Therefore， identifying new potential treatments for depression is crucial. Maintaining a balanced gut microbiota is vital for human health and immune system function due to its complex bidirectional relationship with the brain. Numerous studies have established a robust correlation between anxiety and depression disorders， as well as the composition of microbial communities in the gastrointestinal tract， providing a fresh perspective. Adjusting the balance of gut microbiota may help alleviate depression symptoms. Probiotics， live microorganisms in the human gut， can improve the microbial community， help maintain homeostasis and stress resilience to remission in patients with depression. It’s essential to explore how probiotics affect gut microbiota since their impact can differ between animal experiments and clinical trials. The variation in results may be attributed to factors like the probiotic type， administered dosage， and treatment duration. The purpose of this review is to summarize the potential mechanisms by which probiotics affect gut microbiota， drawing from recent animal and clinical studies and observations on gut microbial ecology shifts. Additionally， this review will spotlight effective probiotic species for depression relief and discuss treatments centered on restoring gut microbial balance. Furthermore， it will also discuss the potential of probiotics on host microbiota in other organs to improve depressive symptoms and demonstrate the transient nature of the need for a more nuanced understanding of the safety and potential adverse effects of probiotics.

在马克思主义文艺理论研究中,经典阐释是一种基本方法,也是一种理论深化的路径。马克思恩格斯等马克思主义经典文艺理论家的论述是马克思主义文艺理论的根本来源,经典阐释从这一来源出发,但不拘泥于摘句式、照搬式、引用式的研究,强调从“经典”走向经典,从马克思恩格斯关于文艺论述的哲学观念、基本精神与方法论启发走向文艺问题的整体理解。马克思主义文艺理论的经典阐释面临不同语境与理论历史发展变化的影响,需要强化问题性选择与论域,需要坚持系统性、问题性、批判性、对话性、当代性的研究路径,通过经典阐释,确立马克思主义文艺理论研究的论述框架和解析方式,在经典阐释、问题介入与批评实践的合理融合中,对马克思主义文艺理论的当代建设提供方案。
