Attomolar Detection of HIV‐1 With Label‐Free RCA‐rCRISPR on Smartphone

Advanced Science, EarlyView.
A new diagnostic strategy integrating rolling circle amplification (RCA) with a plasmid reporter–based ratiometric CRISPR (rCRISPR) system was developed to detect unfragmented HIV genomes with single‐digit attomolar sensitivity. The method quantifies targets using the plasmid relaxation ratio and employs a smartphone‐based mini‐gel device to enable ...

Critical Roles of O‐Acetylation Revealed by Synthetic Trisaccharide Antigens for a Broad‐Spectrum Anti‐Salmonella Vaccine

Advanced Science, EarlyView.
A synthetic glycoconjugate vaccine based on a diacetylated Salmonella trisaccharide elicits broadly protective antibodies against four major human pathogenic serovars. Mechanistic studies identify 2,3‐di‐O‐acetylation of rhamnose as a critical determinant of antigen recognition and breadth of protection, establishing a new strategy for broad‐spectrum ...

IgG Glycosylation‐Dependent CLEC7A Signaling Drives Podocyte Dysfunction in Lupus Nephritis

Arthritis &Rheumatology, EarlyView.
Objective Lupus nephritis (LN) is a severe complication of systemic lupus erythematosus (SLE) that can lead to end‐stage kidney disease and increased mortality. IgG from patients with LN displays abnormal glycosylation, contributing to podocyte injury.

Type I Interferon Drives Dysfunction of a Distinct CD8+ HLA‐DRB1+ T Cell Subset in Systemic Lupus Erythematosus

Arthritis &Rheumatology, EarlyView.
Objective Systemic lupus erythematosus (SLE) is characterized by type I interferon (IFN) signaling and adaptive immune dysregulation. We previously identified hypomethylation of HLA‐DRB1 and STAT1 in SLE CD8+ T cells, enabling aberrant IFN‐driven HLA‐DRB1 expression and expansion of a distinct CD8+ T cell subset. This study characterized CD8+ HLA‐DRB1+
