Dive into the complex pathophysiology of chronic spontaneous urticaria (CSU), where mast cell degranulation drives the hallmark signs and symptoms. This interactive infographic elucidates how key type 2 cytokines, specifically IL-4 and IL-13, contribute to mast cell activation, immune cell trafficking into the skin, and neuronal sensitization in CSU, which ultimately leads to the release of mediators like histamine that cause wheals, angioedema, and itch.

New expert presentations from the 2023 ADVENT FORUM, Dermatology section, where the global faculty discuss itch as the common thread in dermatological type 2 inflammation, the evolving concept of disease modification in atopic dermatitis, and the latest updates in prurigo nodularis and chronic spontaneous urticaria.
This symposium highlights type 2 inflammation as a key driver of chronic itch and the characteristic skin lesions of prurigo nodularis and evaluates the real-world implications of targeted therapies on clinical practice.

Drs Nicola Hanania and Francesca Polverino explore the Many Faces of COPD: From Phenotypes to Endotypes.

Two educational symposia at San Diego, 2024, explore the role of type 2 inflammation and the related manifestations in atopic dermatitis, prurigo nodularis, and chronic spontaneous urticaria.

In this video soundbite from the EAACI 2025 symposium, Dr. Philippe Gevaert explains how biologic options for uncontrolled CRSwNP are increasing, and phase 3 studies of approved biologics show improved outcomes and decreased SCS use/surgery in patients with CRSwNP. Additionally, he explains how biologics targeting type 2 inflammatory pathophysiology potentially improve outcomes for eligible patients with co-existing CRSwNP and asthma.

The March 2025 ADVENT symposium in Orlando, Florida brought together 4 dermatology experts to explore the evolving science of type 2 inflammation. Type 2 inflammation plays a central role in the pathophysiology of multiple dermatological diseases, driving chronic immune dysregulation that affects patients with atopic dermatitis (AD) prurigo nodularis (PN), chronic spontaneous urticaria (CSU) and bullous pemphigoid (BP). Understanding the mechanisms behind type 2 inflammation is key to advancing care and improving patient quality of life.

Many AD treatment goals focus on clinical manifestations, so that if a patient is free of lesions, their disease is considered well controlled. However, the inflammatory process underlying AD reaches far beyond the skin, affecting patients in unique ways at different stages of their lives. Education on the importance of treating AD beyond the skin and altering the treatment approach to fit the individual patient will help improve clinical management and reduce long-term patient burden.

Learn how FeNO, a noninvasive biomarker for type 2 inflammation, can be used to optimize care for asthma patients.

Prof Alan Irvine presents the latest clinical and real-world evidence supporting the potential for disease modification in atopic dermatitis, at EADV 2025.
