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.

In this video from EADV 2025, Dr. Hawkes reviews the pathophysioogy of CSU with a focus on the role of type 2 inflammation
A static infographic detailing how autoimmunity and Type 2 inflammation play a critical role in the pathophysiology of Bullous Pemphigoid (BP).

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.
Learn about the role of type 2 inflammation in the burden and pathophysiology of mucus plugging in severe asthma

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.

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.
Experience this engaging presentation by Dr. Donna Culton, Prof. Dédée Murrell, and Prof. Ulrike Raap, who highlight the heterogeneous clinical presentations of BP and its burden, delve beneath the surface into how autoimmunity and predominantly type 2 inflammation mediate the disease, and explore the evolving toolbox of current approaches in BP management.

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.

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