Allergy and immunology explores how our bodies recognize threats and defend against them, covering everything from seasonal sneezes to complex immune system disorders. This field sits at the intersection of how we react to harmless substances and how our defenses malfunction, affecting millions of people worldwide. Understanding these mechanisms is crucial for developing better treatments and vaccines that keep us safe from both common irritants and serious diseases.

On Gist.Science, we bring you the very latest research directly from medRxiv, ensuring you never miss a breakthrough as it happens. We process every new preprint in this category as soon as it is posted, offering both accessible plain-language summaries and detailed technical breakdowns. This dual approach allows researchers, clinicians, and curious readers to grasp the core findings without getting lost in dense jargon while still having access to the full scientific rigor.

Below are the latest papers in allergy and immunology, updated daily with fresh insights from the global scientific community.

Human RIG-I Antiviral Deficiency Caused by a Dominant-Negative Variant Locked in a Signaling-Inactive State

This study identifies a novel dominant-negative RIG-I variant (G731R) in a severe COVID-19 patient that locks the receptor in a signaling-inactive state by disrupting ATPase activity and preventing signaling domain exposure, thereby causing critical antiviral deficiency.

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.

Application of Impulse Oscillometry Combined with Bronchodilator Testing for Asthma Management: A Children's Hospital Experience in Taiwan

This retrospective study of 225 Taiwanese patients with clinician-diagnosed asthma demonstrates that combining impulse oscillometry with bronchodilator testing effectively evaluates airflow reversibility across age groups, revealing a significant reduction in airway resistance post-administration and a moderate positive correlation between age and proximal airway resistance.

Prevention of Atopic Diseases with the Use of Hypoallergenic Infant Formula: A Systematic Review and Meta-Analysis

This systematic review and meta-analysis of nine randomized controlled trials indicates that while hypoallergenic infant formula significantly reduces the risk of cow's milk protein allergy in high-risk infants, it does not demonstrate a statistically significant protective effect against atopic dermatitis or asthma, though non-significant trends toward risk reduction were observed.

Large-scale GWAS meta-analysis of serum antibody levels in healthy individuals reveals distinct genetic architectures

This study presents the largest GWAS meta-analysis to date of serum IgA, IgM, and IgG levels in over 55,000 healthy individuals, identifying 82 novel genetic associations and revealing that while these antibody isotypes share positive genetic correlations, their specific genetic architectures are largely distinct and closely linked to immune-mediated diseases.

ICI-induced Granulomatous Sialadenitis is Responsive to Prednisone

This paper reports the first case of ICI-induced granulomatous sialadenitis in a patient with papillary thyroid carcinoma, demonstrating that while corticosteroid therapy effectively reduces inflammation and improves salivary function, it cannot fully reverse established fibrosis, thereby highlighting the critical need for early detection and intervention of such immune-related adverse events.
