Understanding Type 2 Inflammation
Welcome to our new Allergy, Asthma & Immunology Innovations podcast series! This is the first episode in a four-part series examining Type 2 Inflammation.
In the first episode, we explore the science behind Type 2 Inflammation, how it affects the body, what conditions are impacted by it and why it’s important for patients to understand.
This episode is produced in partnership with The Itch Podcast. Co-hosts Payel Gupta, MD, and Kortney break down the basics of Type 2 inflammation, explaining how it impacts the immune system and why learning about it can help with better treatment and symptom management.

What happens in Type 2 inflammation?
Type 2 inflammation is a unique immune reaction that leads to extra swelling in the body. It happens when certain immune cells and chemicals, including Th2 cells, cytokines (IL-4, IL-5, IL-13), immunoglobulin E (IgE) antibodies and eosinophils, work together to create Type 2 inflammation.
Key takeaways from Understanding Type 2 Inflammation
This episode examines Type 2 inflammation and its role in allergic and inflammatory diseases.
- What is Type 2 inflammation? Learn how it influences immune system reactions.
- Normal vs. chronic inflammation: understand the difference between short-term immune responses and long-term inflammation.
- How doctors test for Type 2 inflammation: simple blood tests can measure markers like IgE and eosinophils.
- Why Type 2 inflammation is linked to multiple allergic conditions: many people with one allergic condition also have another.
Welcome to the ‘party’: Cells and chemicals involved in Type 2 inflammation
Dr. Payel Gupta discussed Type 2 inflammation using a “party analogy” to help simplify this complex topic.
- Th2 cells are the “party planners” that decide how the immune system responds.
- Cytokines (IL-4, IL-5, IL-13) send text messages telling the body what to do.
- IL-4: Invites “bodyguards” (IgE), which sometimes react to harmless things like pollen or food.
- IL-5: Brings in the “dance crew” (eosinophils), which can lead to swelling and inflammation.
- IL-13: Turns on the “special effects” (mucus and swelling), making asthma and eczema worse.
