Cooperative molecular mimicry drives prolonged autoinflammation in multisystem inflammatory syndrome in children

This study reveals that multisystem inflammatory syndrome in children (MIS-C) is driven by a mechanism of cooperative molecular mimicry, where SARS-CoV-2-specific T cells cross-react with self-antigens involved in prostaglandin biology and insulin metabolism, leading to persistent subclinical autoinflammation even after clinical recovery.

Type I Interferon Signature Strength Correlates with Alloimmunization-Associated Transcriptomic Programs in Systemic Lupus Erythematosus: A Multi-Cohort Analysis

This multi-cohort transcriptomic analysis of 150 Systemic Lupus Erythematosus patients demonstrates that the strength of the Type I interferon signature significantly correlates with alloimmunization-associated gene expression programs, suggesting IFN-I activity as a potential biomarker for transfusion-related alloimmunization susceptibility in SLE.

In Vivo Blood Kinetics and Transcript Integrity of Three mRNA-Lipid Nanoparticle Vaccines in Humans

This study quantifies the systemic persistence and transcript integrity of three mRNA-LNP vaccine platforms in humans, revealing that mRNA-1273 exhibits the fastest decay of both intact mRNA and ionizable lipids compared to BNT162b2 and an investigational RBD vaccine, while demonstrating platform-specific coupling between lipid and mRNA kinetics.

HPV T-cell epitope landscape: systematic mapping of distribution, conservation, and HLA promiscuity of known epitopes to inform immune-monitoring and vaccine design

This study systematically maps the landscape of known HPV T-cell epitopes to reveal a heavy bias toward E6/E7 proteins and high-risk types while identifying critical gaps in conserved regions like L2, thereby providing essential data to guide the development of next-generation pan-HPV vaccines and immune-monitoring strategies.

Exposomics for childhood asthma

By integrating diverse data from the CHILD Cohort Study into the CHILDdb platform, researchers conducted Exposome-Wide Association Studies and machine learning analyses to identify specific early-life exposures, such as antibiotic use and prenatal cleaning product contact, that drive heterogeneous asthma endotypes through epigenetic and microbiome mechanisms, thereby highlighting potential targets for early intervention.

High-dimensional CyTOF profiling reveals distinct maternal and fetal immune landscapes in gestational diabetes mellitus

This study utilizes high-dimensional CyTOF profiling to reveal that gestational diabetes mellitus induces distinct, transiently activated immune phenotypes in maternal T cells and innate lymphoid cells before delivery, as well as a more activated, effector-skewed immune landscape in fetal T and B cells at birth.
