Acetylcholine From Solitary Chemosensory Cell, Not Neuron, Regulates Basal Cell Fate Driving Eosinophilic Chronic Rhinosinusitis With Nasal Polyps

open access: yesAllergy, EarlyView.
This study identifies that Ach levels are elevated in eCRSwNP and primarily released from SCCs rather than neurons. Ach induces epithelial remodeling in eCRSwNP by binding to M1R/M3R and activating YAP signaling in basal cells, driving basal cell hyperplasia and abnormal differentiation. Blocking M1R/M3R with TB inhibits eCRSwNP progression.

Methodology for the Development of the Allergic Rhinitis and Its Impact on Asthma (ARIA)‐EAACI 2024–2025 Guidelines: From Evidence‐to‐Decision Frameworks to Digitalised Shared Decision‐Making Algorithms

open access: yesAllergy, EarlyView.
The Allergic Rhinitis and its Impact on Asthma (ARIA) group is working on the 2024–2025 update of its guidelines for the management of allergic rhinitis (ARIA 2024–2025). The ARIA 2024–2025‐EAACI guidelines will follow GRADE methodology and will incorporate evidence from different sources, including systematic reviews and meta‐analyses, mHealth data ...

Club Cells in Nasal Epithelial Repair: Insights From an IL‐13‐Induced Inflammatory Model

open access: yesAllergy, EarlyView.
Four inflammatory endotypes of CRSwNP, defined by eosinophil and neutrophil infiltration, show distinct patterns of basal, club, ciliated, and goblet cell expression in nasal epithelium. Using an ALI‐HNECs model, we demonstrate that IL‐13 impairs mucociliary function by promoting club‐to‐goblet cell differentiation while inhibiting club‐to‐ciliated ...

Allergic Sensitization to Inhalant Allergens in the Upper Respiratory Tract—the B Cell Side

open access: yesAllergy, EarlyView.
ABSTRACT Allergic diseases are on the rise worldwide, driven by respiratory epithelial barrier dysfunction that promotes sensitization to inhalant allergens such as pollen, dust mites, pet dander, and fungal spores. These antigens trigger IgE‐mediated immune responses that lead to diseases such as allergic rhinitis (AR) and asthma.

Real‐World Performance of FIT Triage for Symptomatic Colonoscopy: Analysis of the UK National Endoscopy Database (NED)

open access: yesAlimentary Pharmacology &Therapeutics, EarlyView.
National endoscopy data show that FIT‐based triage clearly outperforms symptom‐based referral for colorectal cancer risk stratification. FIT ≥ 10 identifies high‐risk symptomatic patients, while FIT < 10 confers very low cancer risk, supporting FIT as the primary tool for prioritising colonoscopy in symptomatic pathways.
