Individuals with positive TG2 autoantibodies but normal small intestinal mucosal morphology are regarded at increased risk of developing CeD and represent patients with potential CeD. The removal of gluten from the diet leads to disappearance of the autoantibodies and normalization of the mucosal architecture in most cases. However, refractory CeD patients deviate from this dogma as they present with abnormal T cell compartment, persistent symptoms and villous atrophy despite a strict gluten-free diet. The heterogeneity of CeD presentation is further diversified by varying symptomatology. Gastrointestinal symptoms are the most canonical signs of CeD, and they include for instance diarrhea, vomiting, constipation and abdominal pain. Yet, a great portion of the patients manifest the disease at extraintestinal sites such as skin, musculoskeletal system or neuronal tissues. Beyond the involvement of various transglutaminase autoantibodies, the detailed immune mechanisms contributing to the development of these manifestations remains elusive, though. This review highlights the current understanding of the immunological differences in various manifestations of CeD.

While immunoglobulin G (IgG) Fc glycosylation is well-characterized, variable domain glycosylation (VDG) introduces an additional and less understood layer of complexity. Notably, VDG is associated with rheumatoid arthritis, where disease-specific IgG autoantibodies abundantly express this modification. Moreover, its presence on these antibodies correlates with disease progression in at-risk individuals and therapeutic outcomes. Emerging evidence links increased VDG levels to other autoimmune diseases and B-cell malignancies, highlighting its potential as both a marker and modulator in disease onset and progression. Importantly, VDG on IgG is now recognized to influence antigen binding, enhance antibody stability, and modulate interactions with the human neonatal Fc receptor. In addition, glycans in the antigen-binding domains of autoreactive B-cell receptors (BCRs) can significantly impact B cell activation. In follicular lymphoma and other B-cell malignancies, the presence of <em>N-</em>glycosylation sites in the immunoglobulin variable domains leads to the introduction of oligomannose glycans, which are postulated to bind to mannose-specific lectins. This interaction might promote antigen-independent activation of BCRs, thereby supporting malignant B cell survival and proliferation. Here, we explore the regulatory pathways of VDG and its functional roles across both physiological and pathological conditions, underscoring its prevalence and significance in various autoimmune diseases and B-cell malignancies. Ultimately, advancing our understanding of the regulatory factors influencing VDG and its functional implications could be highly rewarding for identifying potential therapeutic targets and strategies to prevent and treat autoimmune diseases and B-cell malignancies.</div></div>","PeriodicalId":49546,"journal":{"name":"Seminars in Immunology","volume":"78 ","pages":"Article 101946"},"PeriodicalIF":7.4,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143724882","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This approach is challenging to maintain in real-world settings and in food allergy carries the risk of life-threatening anaphylaxis. Despite their distinct pathogenesis, both disorders are driven by maladaptive responses to dietary proteins, creating opportunities for shared treatment strategies. In food allergy, desensitisation therapies such as oral, sublingual, and epicutaneous immunotherapy are well-established, complemented by biologics like omalizumab and dupilumab. However, the induction of sustained tolerance remains challenging. In contrast, therapeutic advancements for coeliac disease are still in their early stages. Current efforts focus on gluten detoxification or modification, immune blockade or modulation, tolerogenic approaches, and barrier restoration. Emerging therapies, including JAK and BTK inhibitors and microbiome-targeted interventions, support further targeted treatment options for both conditions. Biomarkers tracking gluten-specific T cells have emerged as valuable tools for immunomonitoring and symptom assessment in coeliac disease, although standardisation of patient-reported outcome measures and gluten challenge protocols is still needed. Food allergy trials are reliant on double-blind placebo-controlled food challenges to measure allergen reactivity, but these are time-consuming, carry risks, and underscore the need for surrogate biomarkers. The successful development of immune-targeted therapies will require building an immune toolset to optimally assess systemic responses to antigens in both conditions. Clinically, this could lead to better outcomes for patients who might otherwise remain undiagnosed or untreated due to the absence of significant enteropathy or allergen-specific symptoms.</div></div>","PeriodicalId":49546,"journal":{"name":"Seminars in Immunology","volume":"78 ","pages":"Article 101960"},"PeriodicalIF":7.4,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143864235","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

IRF3 has emerged as an important regulator in the development of obesity and type 2 diabetes (T2D), predominantly through its regulation of inflammatory cytokines production in various cells in adipose tissue. In obese individuals, IRF3 is activated in the adipocytes and adipose tissue macrophages, to promote the expression of inflammatory cytokines, thereby contributing to chronic inflammation and exacerbating insulin resistance. Moreover, IRF3 has been linked to mitochondrial dysfunction in hepatic disorders, further amplifying metabolic stress and imbalances associated with obesity.
