Abstract
Background: Previous studies have suggested that gut microbiota and immune system regulation have potential links with type 2 diabetes (T2D). However, the causal association between gut microbiota and T2D and whether immune cells mediate this interaction is unclear.
Methods: A two-sample, two-step Mendelian randomization (MR) study utilizing an initial inverse-variance weighted (IVW) method was performed to explore the causal impact of gut microbiota on T2D and the intermediary role of immune cells.
Results: The MR analysis assigned 4 gut microbiota and metabolic pathways that increase the risk of T2D (G_Prevotella, g_Anaerotruncus, g_Streptococcus.s_ Streptococcus_parasanguinis, and the pathway of PANTO-PWY) and 4 other gut microbiota and metabolic pathways that have a protective effect against T2D (PWY5667, PWY-6892, PWY-7221, and the bacterial g_Paraprevotella.s_Paraprevotella_ clara). Furthermore, 17 immune cell traits have been identified as associated with T2D. The finding from mediation MR analysis revealed that PANTO-PWY increases T2D risk via CD3 on HLA DR+ CD4+, whereas PWY-7221 reduces T2D risk through CD4 on CD4 Treg.
Conclusion: The research reveals a mediated causal link between the gut microbiota and T2D via immune cells.
期刊介绍:
Current Molecular Medicine is an interdisciplinary journal focused on providing the readership with current and comprehensive reviews/ mini-reviews, original research articles, short communications/letters and drug clinical trial studies on fundamental molecular mechanisms of disease pathogenesis, the development of molecular-diagnosis and/or novel approaches to rational treatment. The reviews should be of significant interest to basic researchers and clinical investigators in molecular medicine. Periodically the journal invites guest editors to devote an issue on a basic research area that shows promise to advance our understanding of the molecular mechanism(s) of a disease or has potential for clinical applications.
