Genome editing technologies have been widely utilized in cell engineering, demonstrating immense potential in cell and gene therapy. However, an optimal gene-editing enzyme for immune cell editing remains unidentified. In this study, we identified a novel gene editing enzyme, termed CRISPR/PcoCas12a, derived from Prevotella copri, which recognizes a 5'-YYN PAM sequence.

Background: The human microbiome is crucial in regulating intestinal and systemic functions. While its role in cardiovascular disease is better understood, the link between intestinal microbiota and valvular heart diseases (VHD) remains largely unexplored.
Methods: Peer-reviewed studies on human, animal or cell models analysing gut microbiota profiles published up to April 2024 were included.

Gut microbiota regulates the immune system, the development and progression of autoimmune diseases (AIDs) and overall health. Recent studies have played a crucial part in understanding the specific role of different gut bacterial strains and their metabolites in different AIDs. Microbial signatures in AIDs are revealed by advanced sequencing and metabolomics studies.

This study evaluated the effects of two synbiotic strategies on the intestinal microbiota and immune response in Beagle dogs. Twelve dogs were subjected to a crossover design with three diets: a control diet (CON), a diet supplemented with fiber and DSM 15544 (SYN), and the SYN diet with added porcine plasma (SYN+). Over three periods of seven weeks, fecal samples were analyzed for digestibility, short-chain fatty acids (SCFA), fecal markers, and microbiome composition, while blood samples were assessed for biochemical parameters, leucocytic counts including CD4/CD8 lymphocyte populations, and phagocytic activity.

Duke-NUS Medical School, Singapore.
Background: Cholecystectomy (CCE) can affect the enterohepatic circulation of bile acids and result in gut microbiome changes. This systematic review aimed to clarify the effect of CCE on gut microbiome composition and its clinical impact.
Method: A systematic search was conducted in PubMed, Web of Science, and Scopus, combining keywords such as "cholecystectomy" or "post-cholecystectomy" with "gut microbiome," "stool microbiome," or "gut dysbiosis.
