A VLP-based immunogen that elicits selective anti-Myostatin antibodies, enhances muscle mass and strength, and reduces adiposity

This study presents MS2.87-97, a cost-effective and durable virus-like particle-based immunotherapy that selectively targets myostatin to increase muscle mass and strength while reducing adiposity in mice, offering a promising alternative to monoclonal antibodies for treating obesity and sarcopenia without observed cardiac safety concerns.

Intranasal Anti-CD3 Antibody Treatment Attenuates Post-COVID Neuroinflammation and Enhances Hippocampal Neurogenesis and Cognitive Function in Mice

This study demonstrates that intranasal administration of anti-CD3 monoclonal antibodies attenuates post-COVID neuroinflammation and restores hippocampal neurogenesis and cognitive function in mice by reprogramming microglia and expanding regulatory T cells, suggesting a promising noninvasive therapeutic strategy for Long COVID-related cognitive impairment.

Longitudinal and stability-aware analysis reveals treatment-specific microRNA response signatures following immune-reconstitution and B-cell-targeted therapies in multiple sclerosis

This study utilizes a longitudinal, stability-aware framework to demonstrate that cladribine and ocrelizumab induce distinct, non-overlapping microRNA response signatures in multiple sclerosis patients, reflecting their divergent immunological mechanisms through coordinated upregulation of specific miRNAs associated with Th17/Treg balance and Wnt signaling for cladribine versus mTOR and NF-κB pathways for ocrelizumab.

Urine proteomic profiling at admission reveals complement biomarkers linked to alcohol-associated liver disease.

This study demonstrates that urinary complement protein signatures, which are independent of plasma levels and associated with short-term mortality, serve as effective biomarkers for distinguishing severe alcohol-associated hepatitis from alcohol cirrhosis while offering insights into liver-kidney crosstalk mechanisms in alcohol-associated liver disease.

Metabolic Drivers of Disease Activity and Complications in Crohns Disease: A Retrospective Cross-Sectional Study

This retrospective study of 376 adults with newly diagnosed Crohn's disease identifies lower BMI, lower HDL-C, and higher triglycerides as independent metabolic drivers associated with increased disease activity and a higher risk of complications, demonstrating that models using these specific parameters outperform ratio-based approaches in predicting clinical outcomes.

Human Lymph Node Cellular Senescence Atlas Reveals Age-Dependent Alteration in Germinal Center B Cell Function and Niches

This study integrates single-cell and spatial multi-omics to construct a comprehensive atlas of human lymph nodes, revealing that aging drives a stepwise shift in senescent cell localization toward germinal centers and induces focal clonal-like senescence in B cells, thereby contributing to age-related immune decline.

Human neonatal CITE-seq atlas identifies an immune transition at 32 weeks' gestation from CD15+ myeloid-dominated to interferon-primed immunity

This study presents a comprehensive human neonatal CITE-seq atlas that reveals a critical immune transition at 32 weeks' gestation, shifting from a CD15+ myeloid-dominated state in extremely preterm infants to an interferon-primed immunity in more mature neonates, thereby defining gestational age-specific immune programs and vulnerabilities.
