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.

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.
Type 2 inflammation contributes to many dermatologic diseases, which may lead to potentially life-changing burdens and challenges to patients and caregivers. By uncovering the role of type 2 inflammation in the pathophysiology of AD, PN, CSU, and BP, we can move forward in our understanding of each disease. Join global experts for an educational symposium on March 8th that will uncover the role of type 2 inflammation in the pathophysiology of AD, PN, CSU, and BP and explore questions driving current research in each disease.

Join Christine Bangert, Mark Boguniewicz and Perla Lansang for an educational symposium on atopic dermatitis (AD) in children, exploring the diagnosis and pathophysiology of AD in children, the life-long effects of uncontrolled disease beyond the skin, and current and emerging therapies.

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 underlying pathophysiology of atopic dermatitis (AD) is driven by dysregulation of type 2 immunity that contributes to skin barrier dysfunction. AD typically develops very early in life and children with AD often develop other atopic conditions such as food allergy, asthma, and allergic rhinitis in a progression called the atopic march. Early treatment may help reduce the atopic march and other comorbidities to lessen the lifetime burden created by these diseases. There may even be a window of opportunity for disease modification.

In this educational presentation, Profs. Vibeke Backer and Sietze Reitsma cover key aspects of type 2 inflammation and its role in the pathogenesis and management of CRSwNP and practical strategies for optimizing disease control and improving patient outcomes.

Professor Lisa Beck explores the chronic and persistent burden of atopic dermatitis (AD) as well as the concept of early intervention in patients with AD.

In this expert interview video focusing on topics from the September 2024 ADVENT symposium at EADV’s Annual Meeting in Amsterdam, the Netherlands, Dr. Stephan Weidinger discusses how type 2 inflammation contributes to the systemic inflammation seen in patients with moderate-to-severe AD.
