Antiphospholipid antibodies (aPL) trigger a diverse array of innate immune pathways, including the complement system, neutrophils, and the inflammasome, leading to trophoblast dysfunction, poor placentation, and ultimately, adverse pregnancy outcomes such as recurrent miscarriage, preeclampsia, and fetal growth restriction. The current standard of care, low-dose aspirin combined with heparin, primarily targets coagulation and has limited efficacy in controlling the underlying inflammatory response, resulting in treatment failure in approximately 20–30% of patients. This review aims to redefine the inflammatory nature of OAPS, elaborate on the immune-pathological network centered on the placenta, and critically examine the pivotal role of the signaling cascade mediated by TLR4 that activates the downstream NF-κB transcription factor as a major regulatory node of the inflammatory response. In this context, experimental inhibitors target the initiation of this cascade at the receptor level to prevent the subsequent nuclear translocation of NF-κB. Building on this, we review the evolution of treatment strategies from traditional anticoagulants to immunosuppressants and propose that “targeting the local placental immune microenvironment” is the core direction for future therapies. Finally, this paper discusses a novel snail-inspired bioactive substance, specifically focusing on the natural glycosaminoglycan AFG (Achatina fulica glycosaminoglycan).

IL-10 receptor (IL-10R) consists of two chains of ligand-binding IL-10RA and two subunits of IL-10RB.

Mutations in the IL10, IL10R cause spontaneous colitis in mice model and very early onset inflammatory bowel disease (VEOIBD) in human. Patients who have disease onset before 6 years of age are defined as VEOIBD. IL10 and IL10 receptor defect are classified as one type of monogenic inborn errors of immunity (IEI). IL-10 signalling defects demonstrate a Mendelian inheritance pattern with complete penetrance of intestinal inflammation. Patients develop symptoms during infancy and have more severe phenotype than polygenic inflammatory bowel disease (IBD). Here, we review the recent advances in the genetic mechanism, population dynamics and innate and adaptive immune dysregulation and interactions of gut microbiota regarding IL-10 signalling defects. The understanding of the pathogenesis has informed therapeutic strategies including haematopoietic stem cell transplant and novel biologics such as interleukin 1 receptor antagonist. Optimised transplant regimen and decreased risk of graft versus host disease with gut immunomodulation with vedolizumab might be used to improve transplant outcomes. More recently, gene therapy and gene editing have become treatment options for a range of IEIs, however evidence for IL-10 signalling defects is limited to in vitro and in vivo models.

While genetic predisposition plays a role in AR development, environmental factors, particularly air pollution, have emerged as critical contributors. This review comprehensively examines epidemiological evidence linking air pollutants—such as particulate matter, hazardous gases, traffic-related air pollution (TRAP), volatile organic compounds (VOCs), and environmental tobacco smoke (ETS)—to AR prevalence and severity. Furthermore, it explores the synergistic interactions between air pollutants and inhaled allergens, highlighting mechanisms through which air pollution exacerbates AR. These mechanisms include disruption of nasal epithelial barrier function, enhancement of IgE-mediated hypersensitivity, oxidative stress, amplification of inflammatory responses, epigenetic modifications, alterations in microbial communities, and neurogenic regulation. Despite significant advances, the complex interplay between air pollutants and AR is not yet fully delineated.

CRS, a prevalent inflammatory condition, commonly leads to diminished or complete loss of smell. A substantial component of CRS-associated OD is conductive, stemming from impaired odorant delivery to the olfactory neuroepithelium. The tools for assessing conductive OD range from clinical evaluations like endoscopy and CT scoring of the olfactory cleft to objective measures of nasal patency and advanced computational fluid dynamics modeling. The underlying conductive mechanisms are multifactorial, primarily involving two interrelated pathways: alterations in nasal airflow dynamics due to anatomical variations or obstructive lesions, and pathological changes in the physicochemical properties of olfactory cleft mucus. Obstructions from septal deviation, turbinate hypertrophy, nasal polyps, and mucosal edema within the olfactory cleft disrupt and redistribute inspiratory airflow, critically reducing odorant access. Concurrently, inflammation-driven changes in the olfactory mucus—including hypersecretion, ionic imbalance, and deficiencies in odorant-binding proteins and metabolizing enzymes—impair odorant transport, solubilization, and signal transduction. Current therapeutic strategies, such as endoscopic sinus surgery and corticosteroids, aim to relieve these conductive barriers but may offer only partial or temporary benefit, highlighting the need for precise phenotyping. A systematic, individualized assessment of both airflow patterns and mucus properties is crucial for understanding the conductive contribution and predicting outcomes.

While recurrent infections remain a classical hallmark of IEI, non-infectious manifestations such as autoimmunity, lymphoproliferation, and autoinflammation are often the dominant or presenting features, posing diagnostic challenges. OBJECTIVE: To identify clinical features associated with IEI in children presenting with manifestations of immune dysregulation. METHODS: We conducted a multicenter retrospective–prospective cohort study including 106 children with manifestations of immune dysregulation evaluated at tertiary centers. Patients were stratified according to the presence or absence of genetically confirmed IEI. RESULTS: The group with genetically confirmed IEI comprised 67 patients, whereas the group with immune dysregulation without confirmed IEI comprised 39 patients. Several clinical features were significantly associated with genetic confirmation of IEI, including multilineage cytopenia (OR 6.27, 95% CI 1.74–22.59), Evans syndrome (OR 8.29, 95% CI 1.03–66.47), and lymphoproliferation (OR 4.20, 95% CI 1.55–11.35). Combined immune dysregulation phenotypes, such as autoimmunity with lymphoproliferation (OR 2.88, 95% CI 1.05–7.86) and autoimmunity with infections (OR 2.82, 95% CI 1.24–6.38), were also associated with genetic confirmation of IEI. Among genetically confirmed cases, disorders of immune dysregulation represented the largest subgroup (37.3%), followed by predominantly antibody deficiencies (31.3%) and syndromic or combined immunodeficiencies (16.4%). CONCLUSIONS: Specific patterns of immune dysregulation, particularly multilineage cytopenias, Evans syndrome, lymphoproliferation, and combined autoimmune phenotypes, were associated with genetically confirmed IEI in this cohort.
