Open Access: Need to Assess On-Demand Versus Continuous Treatment in Allergic Rhinitis in ARIA-EAACI Guidelines. Corresponding author: Jean Bousquet Read the article here: doi.org/10.1111/all.70498

There is ongoing discussion on whether patients with allergic rhinitis should receive continuous long-term or on-demand treatment. In this Letter, Bousquet et al., point to the low medication adherence observed in MASK-air studies and by physicians with allergic rhinitis. The study recognizes that this data was obtained from selected populations and that there is a need for dedicated guideline recommendations.

The ɑ-hairpinin of Ara h 1 contains a dominant epitope that is both frequently recognized and blocks a majority of the IgE against this domain. Including this region in tests may improve diagnosis of peanut allergy. The trimeric structure of the vicilin region explains the ability of Ara h 1 to induce anaphylaxis with a single antibody.

Impaired Clearance of Neutrophil Extracellular Traps in Stevens–Johnson Syndrome/Toxic Epidermal Necrolysis. Corresponding author: Manao Kinoshita 👉 doi.org/10.1111/all.70507 Read more articles here: journalallergy.com/Drug-Insect-Anaphylaxis #Allergy_journal

Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN) is a rare, albeit life-threatening, adverse skin reaction to certain medications. Kinoshita et al. demonstrate that neutrophil extracellular trap (NET) degradation is impaired in SJS/TEN patients due to DNase 1 dysfunction, as patients were observed to exhibit significantly reduced DNase 1 activity and levels. The NET accumulation is further aggravated by inhibition of DNase 1 by G-actin released from necroptotic keratinocytes.

A Strong Proposal for the Reasons of Pandemic Increase in Food Allergies Could common food emulsifiers affect intestinal barrier integrity and IgE immune responses? Read the open-access article: doi.org/10.1111/all.70473 @epithelial-barrier.bsky.social #Allergy_journal journalallergy.com

In this new study, SIAF researchers and their international collaborators investigated soy lecithin and DATEM, two widely used emulsifiers found in processed foods, including some peanut butters.

Using human gut-on-a-chip and adult stem cell-derived colon organoid-on-a-chip models, together with human immune cells and mouse models, the researchers found that both emulsifiers:
🔹 Disrupted intestinal epithelial barrier integrity
🔹 Activated pro-inflammatory pathways, including TNF and NF-κB signalling
🔹 Induced local and systemic inflammatory responses
🔹 Stimulated particularly IgEantibody responses

Soy lecithin additionally induced oxidative stress and increased IgE levels in mice, while DATEM enhanced IL-4-induced IgE production in human peripheral blood mononuclear cells.

These findings support the Epithelial Barrier Theory and highlight the need to consider barrier dysfunction and low-grade immune activation when evaluating the biological effects of commonly used food additives. Further studies are needed to determine their long-term effects in humans.

Congratulations to the entire research team on this publication!

Using TLR4 knockout bone marrow-derived macrophages and HEK293 cells transfected with TLR4, Zlatanova et al., demonstrate that the enzymatic function of Act d 1 is essential for TLR4 activation. The authors propose an alternative mechanism of receptor activation where Act d 1 cleaves the TLR4 ectodomain, thereby removing the domain responsible for maintaining TLR4 in an inactive state in the absence of its ligand.

Tezepelumab Reverses TSLP-Driven Immunometabolic Rewiring in Human cDC2s Underlying Pathogenic Th2 and Dysfunctional Treg Responses. First author: Leticia Martín-Cruz; corresponding author: Oscar Palomares 🌟 doi.org/10.1111/all.70470

This study aimed to determine whether thymic stromal lymphopoietin (TSLP) induces a pathogenic immunometabolic program in human type 2 conventional dendritic cells (cDC2s) and whether tezepelumab can directly reverse this process. TSLP rewires human cDC2 metabolism by increasing both glycolysis and mitochondrial oxidative phosphorylation. This metabolic shift drives a pro-type 2 phenotype required to generate pathogenic Th2 cells and functionally impaired FOXP3+ Tregs. Tezepelumab effectively restores normal metabolic and functional properties in cDC2s, inhibiting Th2 polarization and rescuing Treg function.

Soy lecithin (E322) and diacetyl tartaric acid ester of mono- and diglycerides (DATEM, E472e), the two commonly used food emulsifiers introduced into many foods including peanut butter and puffed bread, in the 2000s, impair intestinal epithelial barrier integrity in human gut-on-a-chip and induced pluripotent stem cell colon organoid models. Both emulsifiers activate NF-κB/TNF-driven inflammatory pathways and induce stress responses and apoptosis in epithelial cells, with soy lecithin additionally triggering oxidative stress and suppressing aryl hydrocarbon signaling in gut epithelial cells. Oral exposure to emulsifiers within the range of daily doses induces local gastrointestinal and systemic inflammatory responses in mice and increases IgE and IgG responses, suggesting a role in the development of allergies.

In bronchial biopsies, senescence-associated secretory phenotype (SASP) and p53 pathway enrichment scores are elevated in severe asthma versus non-severe asthma and healthy controls. SASP enrichment is validated in the independent Newcastle severe asthma cohort (NOVA). SASP enrichment is also elevated in nasal brushings of participants with nasal polyps, independently of asthma status. Senescence pathway enrichment associates with exacerbations, daily oral corticosteroid (OCS), lower post-bronchodilator (post-BD) forced expiratory volume in 1 s (FEV1%) and macrophage/oxidative phosphorylation (OXPHOS) signatures, but not with Th2/eosinophil signatures, supporting a non-T2 mechanism.

Open Access: Determinants of Poor Health-Related Quality of Life in Patients With Food Allergy. First author: Rosialzira Natasha Vera-Berrios; corresponding author: Montserrat Fernández-Rivas Read the article here: doi.org/10.1111/all.70418

Machine-learning analysis of 502 well-characterised food-allergic patients was used to identify key determinants of poor food allergy-health-related quality of life (FA-HRQL), defined as FAQLQ ≥ 5. The most relevant predictors were adult age, female sex, multiple food allergies, severe reactions, need for urgent care, onset before 18 years, and longer disease duration. Adult women with multiple food allergies showed the poorest FA-HRQL.

Open Access: Distinct Skin Penetration and Immune Responses to Ionic and Nanoparticulate Cobalt in Allergic Contact Dermatitis. P. Werner, M. Schaier, G. Braun, A. Julander, K. Midander, M. Isaksson, G. Koellensperger, L. Wisgrill, N. Fyhrquist Read the article here: doi.org/10.1111/all.70422

Cobalt chloride (CoCl2) and cobalt nanoparticles (CoNPs) induce a shared, severity-dependent inflammatory response in cobalt-sensitized skin characterized by activation of interferon signaling, inflammatory pathways (TNF/NF-κβ, IL6-STAT3), apoptosis/unfolded protein response (UPR), cell cycle programs, and glycolysis. Despite comparable nominal exposure, the two cobalt forms exhibit distinct tissue distribution: CoCl2 penetrates deeply and accumulates intracellularly across epidermal and dermal compartments, whereas CoNPs are largely retained in the stratum corneum. Direct comparison reveals divergent transcriptional programs, with CoCl2 preferentially inducing interferon and antiviral responses (e.g., IRF7), and CoNPs promoting keratinization and epithelial differentiation (e.g., KRT25). Together, these findings demonstrate that cobalt speciation and penetration depth shape tissue exposure and downstream immune responses in allergic contact dermatitis.

Patient-derived expanded potential stem cell (EPSC) hepatocytes reveal that pathogenic SERPING1 variants cause distinct cellular defects in hereditary angioedema. While most mutations reduce SERPING1 transcription and C1-INH secretion, a large deletion induces intracellular C1-INH retention. Reciprocal CRISPR repair and installation confirm mutation-specific causality.

Dong et al., provide transmission electron microscopy (TEM) and hyperspectral images to demonstrate that silica particles present in, for example, sandstorms form a protein corona with nasal mucosal components in the nasal cavity. These allergens aggravate pre-existing allergic rhinitis by disrupting the nasal epithelial barrier and promoting immune activation related to allergic diseases.

Skin prick automated tests (SPAT) reduce operator-dependent variability by applying a fixed amount of allergen at a standardized prick force. AI-assisted readouts provide wheal measurement suggestions, thereby reducing inter- and intra-physician variability. This study analysed real-world SPAT data from 37 hospitals across 5 European countries, including 10,756 patients with various allergic diseases. Their findings support the integration of an AI-assisted readout model in clinical practice.

Mitochondrial fatty acid enzyme, CPT1A, is deficient in the airway epithelium of severe #asthma patients. Restoration of CPT1A expression improved epithelial barrier integrity via increasing mitochondrial respiration and ATP production in airway epithelial cells. Restoration of deficient epithelial CPT1A may represent a new treatment approach for severe asthma.
