1 source·Aug 10, 2026 This research identifies interleukin 17 receptor A (IL17RA) as a novel, direct ligand for the Vδ7 γδTCR in mice, a discovery that clarifies long-standing mysteries regarding γδT cell antigen recognition . Using cDNA library screening and surface plasmon resonance, the authors demonstrate that IL17RA interacts with germline-encoded regions of the Vδ7 chain rather than traditio...

The research article examines how mature type 1 conventional dendritic cells (cDC1s) act as the primary architects and keepers of tertiary lymphoid structures (TLSs) in cancerous environments. Using advanced spatial transcriptomics and mouse models, the study demonstrates that these immune cells undergo IFN-γ-driven maturation to initiate the early formation of lymphoid aggregates. As tumors advan...

This research article identifies a novel method of horizontal protein transfer where bacteria exchange functional proteins via membrane vesicles to survive antibiotic stress. Researchers developed a Cre-loxP genetic system to track these events, discovering that antibiotics trigger a population to split into vesicle-producing donors and protein-receiving recipients . This exchange is driven by the...

This research article details a large-scale study on single-cell multiomics to understand how neuronal activation reveals the genetic foundations of neuropsychiatric disorders (NPD) .

Scientists have developed a new class of de novo–designed proteins called WRAPs (water-soluble RFdiffused amphipathic proteins) to solve the long-standing challenge of membrane protein solubilization . These artificial proteins are engineered using deep learning tools like RFdiffusion to "wrap" around the water-repelling regions of membrane proteins, allowing them to remain stable in water without...

This research introduces Metabolic Reprogramming in Ischemic Stroke (MRIS) as a unifying framework that redefines stroke as a systemic bioenergetic failure rather than a localized vascular event. The authors describe a chronological progression of damage, beginning with an acute glycolytic crisis and energy collapse that transitions into a subacute "lipid storm" driven by toxic peroxidation. This...
