Effects of moderate beer consumption on immunity and the gut microbiome in immunosuppressed mice.

Beer contains a variety of bioactive ingredients and trace elements that can regulate bodily functions, and moderate consumption of beer can enhance immune responses. This study aimed to investigate the potential benefits of moderate consumption of alcoholic or non-alcoholic beer on the gut microbiome, immunity, and intestinal barrier function in immunosuppressed BALB/c mice induced by cyclophosphamide (CTX). Model mice with CTX-induced immunosuppression were administered alcoholic or non-alcoholic beer or galacto-oligosaccharides (GOS) for 28 consecutive days.

Comprehensive analysis of scRNA-seq and bulk RNA-seq reveals the non-cardiomyocytes heterogeneity and novel cell populations in dilated cardiomyopathy.

Background: Dilated cardiomyopathy (DCM) is one of the most common causes of heart failure. Infiltration and alterations in non-cardiomyocytes of the human heart involve crucially in the occurrence of DCM and associated immunotherapeutic approaches.

Methods: We constructed a single-cell transcriptional atlas of DCM and normal patients.

Sex hormone imbalance and rheumatoid arthritis in American men: a cross-sectional analysis from NHANES 2011-2016.

Background: Emerging evidence suggests that sex hormones, particularly testosterone and sex hormone-binding globulin (SHBG), play a critical role in the pathophysiology of Rheumatoid arthritis (RA). However, the precise relationship between these hormonal factors and RA risk in men remains underexplored.

Methods: We conducted a cross-sectional analysis using data from the National Health and Nutrition Examination Survey (NHANES) 2011-2016.

Protein Phosphatase 2A Promotes CD8 T Cell Effector Function through the Augmentation of CD28 Costimulation.

Protein phosphatase 2A (PP2A) is one of the most abundant serine/threonine phosphatases and plays critical roles in regulating cell fate and function. We previously showed that PP2A regulates the differentiation of CD4 T cells and the development of thymocytes. Nevertheless, its role in CD8 T cells remains elusive.

Real-time analysis of nanoscale dynamics in membrane protein insertion via single-molecule imaging.

Membrane proteins often need to be inserted into or attached to the cell membrane to perform their functions. Understanding their transmembrane topology and conformational dynamics during insertion is crucial for elucidating their roles. However, it remains challenging to monitor nanoscale changes in the insertion depth of individual proteins in membranes.
