Multi-omics analyses reveal the pathogenic role of terminal ileum-derived IgA+β7+ cells in IgA nephropathy.
Key Points
The research aims to understand the role of terminal ileum-derived IgA+β7+ cells in IgA nephropathy (IgAN).
Conducted multi-omics analyses of B cell behavior in the terminal ileum.
Examined the interactions between α4β7 and MAdCAM-1.
Analyzed the dysregulation of B cell responses in IgAN.
Identified a significant correlation between IgA+β7+ cells and IgAN severity.
Revealed potential therapeutic targeting of the α4β7-MAdCAM-1 axis.
Demonstrated dysregulation of B cell responses in the terminal ileum contributing to IgAN.
Abstract
Our study highlights the importance of dysregulated B cell responses in the terminal ileum in IgAN and suggests the α4β7-MAdCAM-1 axis as a potential therapeutic target.
