ABSTRACT
Gut microbiota is a complex and dynamic system, and is essential for the health of the body. As the "second genome" of the body, it can establish communication with the important organs by regulating intestinal nerves, gastrointestinal hormones, intestinal barrier, immunity and metabolism, thus affecting host′s physiological functions. Short chain fatty acid (SCFA), known as one important metabolite of intestinal microbiota, is regarded as a significant messenger of the gut-organ communication, due to its extensive regulation in the body′s immunity, metabolism, endocrine and signal transduction. In this review, we summarize the interaction between gut-liver/brain/kidney/lung axis and diseases, and focus on the role and mechanism of SCFA in the gut-organ communication, hoping to provide new ideas for the treatment of the related diseases.
ABSTRACT
This paper aims to present a review of the research progress on the roles of mitochondrial dysfunction and microglia-mediated inflammation in the pathophysiology of schizophrenia. Schizophrenia is a serious psychiatric disorder in which the immuno-inflammatory pathway is considered to be one of the main pathogenic mechanisms of disease， and manifested by microglia activation and elevated levels of inflammatory cytokines in the brain. However， the biological mechanism underlying immune disorder in schizophrenia has not been fully elucidated. In recent years， accumulating evidence has indicated that mitochondrial dysfunction may play a key role in the pathogenesis of schizophrenia. Therefore， this article reviews the research progress on the roles of mitochondrial days function and microglia-mediated inflammation in the pathophysiology of schizophrenia， so as to inform the study of the pathogenesis of schizophrenia.
