Abstract
There has been increasing interest in the connection between AD, gut microbiota, and metabolites. Kai-Xin-San (KXS) has been commonly employed in ancient and modern Chinese clinical trials for the treatment of dementia; however, whether the protective effect of KXS in AD is related to the gut microbiota remains elusive. APP/PS1 mice were used as the model of AD. 43 key metabolites influenced by KXS were screened using untargeted metabolomics. At the genus level, Clostridium_IV, Eubacterium, Acetatifactor, etc., were identified to be impacted by KXS using 16S rRNA sequencing. Additionally, we identified 9 distinct intestinal floras at the genus level that were correlated with 13 pivotal differential metabolites related to cognitive impairment. KXS also inhibited the neuroinflammation, mostly via regulating the key metabolites. A potential relationship between gut microbiota, metabolites, and neuroinflammation is suggested as a protective mechanism of KXS in AD. These findings provide support for further development of KXS.
期刊介绍:
Science has many big remaining questions. To address them, we will need to work collaboratively and across disciplines. The goal of iScience is to help fuel that type of interdisciplinary thinking. iScience is a new open-access journal from Cell Press that provides a platform for original research in the life, physical, and earth sciences. The primary criterion for publication in iScience is a significant contribution to a relevant field combined with robust results and underlying methodology. The advances appearing in iScience include both fundamental and applied investigations across this interdisciplinary range of topic areas. To support transparency in scientific investigation, we are happy to consider replication studies and papers that describe negative results.
We know you want your work to be published quickly and to be widely visible within your community and beyond. With the strong international reputation of Cell Press behind it, publication in iScience will help your work garner the attention and recognition it merits. Like all Cell Press journals, iScience prioritizes rapid publication. Our editorial team pays special attention to high-quality author service and to efficient, clear-cut decisions based on the information available within the manuscript. iScience taps into the expertise across Cell Press journals and selected partners to inform our editorial decisions and help publish your science in a timely and seamless way.
