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.

Determinants of total and inhaled allergen-specific immunoglobulin E in the middle-aged and elderly population

This study of the Rotterdam Study cohort identifies age, sex, smoking status, BMI, season, and corticosteroid use as key determinants of total and inhaled allergen-specific IgE levels in middle-aged and elderly adults, suggesting that accounting for these factors can improve the clinical interpretation of IgE for allergic conditions.

Standardised Human Phenotype Ontology Annotation Enables High Quality Phenotypic Data Capture in a Real-World Common Variable Immunodeficiency Cohort

This study demonstrates that implementing a standardized Human Phenotype Ontology (HPO) framework with clinician training enables high-quality, granular phenotypic data capture in a large UK CVID cohort, successfully linking specific immune profiles and genetic variants to distinct clinical subgroups to advance genotype-phenotype understanding and therapeutic strategies.

A Genetically Driven Immunologic Mechanism Underlying the Link between EBV and Multiple Sclerosis

This study establishes a genetically driven immunologic mechanism linking Epstein-Barr virus to multiple sclerosis by identifying shared genetic risk loci and demonstrating that EBV-infected memory B cells alter differentiation and upregulate cytokines and risk genes to modulate T cell activation.

Yasumizu, Y., Kim, N., Rivier, C. A., Moon, J., Kojima, S., Chen, H.-L., Buitrago-Pocasangre, N., Silberfeld, A., Quinn, E., Vaughn, S., Morgan, A., Huo, S., Silberfeld, A., Sumida, T. S., Ishigaki, K (…)2026-04-13📄 allergy and immunology

Comprehensive Immunophenotyping of Monocytes and Dendritic Cells Suggests Distinct Pathophysiology in Chronic Fatigue Syndrome and Long COVID

This study utilizes multiparameter immunophenotyping of 207 participants to demonstrate that while both ME/CFS and long COVID present with overlapping clinical features, they are driven by distinct immunopathological mechanisms characterized by immune exhaustion in long COVID versus immune suppression in ME/CFS.

Petrov, S. I., Bozhkova, M., Ivanovska, M., Kalfova, T., Dudova, D., Todorova, Y., Dimitrova, R., Murdjeva, M., Taskov, H., Nikolova, M., Maes, M.2026-04-12📄 allergy and immunology

Integrative Genomic and Immune Repertoire Profiling Identifies Clonal Signatures Linked to Antithyroid Drug-Induced Agranulocytosis

This study identifies distinct clonal signatures in T cell receptors associated with antithyroid drug-induced agranulocytosis, revealing that HLA-B*38:02 and HLA-DRB1*08:03 risk alleles drive disease pathogenesis through specific expansions of CD8+ effector memory and CD4+ central memory T cell clones, respectively.

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.

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.

Solotchi, M., Jing, H., Gebauer, E., Novick, S. J., Pascal, B. D., Tung, W., Hanpude, P., Zhang, Y., Alba, C., Saracino, A., Laghetti, P., Shaw, E. R., Rosen, L. B., Holland, S. M., Lisco, A., Dalgard (…)2026-03-06📄 allergy and immunology

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.
