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.

Watch this short video to learn how type 2 inflammation, skin barrier dysfunction, and neurosensitization contribute to chronic itch and the itch-scratch cycle in atopic dermatitis
Listen to the latest updates in type 2 inflammatory science and associated skin diseases, brought to you by leading dermatology experts in the field. ADVENT On Air podcasts feature scientific conversations that explore new research into the pathophysiology, clinical features, and disease burden for a range of dermatological diseases linked to type 2 inflammation, including atopic dermatitis (AD) and prurigo nodularis (PN). Hear new insights revealed through expert-led conversations below or in your preferred podcast app.


In this video from EADV 2025, Dr. Hawkes reviews the pathophysioogy of CSU with a focus on the role of type 2 inflammation
Learn about the role of type 2 inflammation in the burden and pathophysiology of mucus plugging in severe asthma
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.

Join experts Vibeke Backer, MD, DMSC, and Sietze Reitsma, MD, at an educational symposium involving a comprehensive exploration of the type 2 inflammation and its pivotal role in the pathogenesis and management of CRSwNP.

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.

Join Dr. Hanania to understand how to identify patients at risk of fixed airway obstruction in clinical settings.

Join Dr. Celeste Porsbjerg as she discusses on how IL-13 contributes to mucus plugging in asthma.
