High-resolution single-cell atlas of the human B cell compartment and immune microenvironment across tissues

This study maps human B-cell populations and their interactions across 10 tissues using single-cell RNA sequencing, revealing tissue-specific adaptations and residency gene modules.

Rare predicted loss-of-function variants of type I IFN immunity genes are associated with critical COVID-19

The paper identifies rare loss-of-function variants in type I IFN immunity genes associated with severe COVID-19, particularly in younger patients with recessive inheritance.

Genetic regulation of serum IgA levels and susceptibility to common immune, infectious, kidney, and cardio-metabolic traits

This study identifies 20 genome-wide significant loci associated with serum IgA levels and finds genetic correlations with various immune and metabolic traits.
