Asthma: Horses, Fish Scale, IgE - The Story of Elucidating the Mechanism of Allergies

Season 1 · Episode 10

Monday, July 27, 2026 • Duration 24:52

A blood transfusion, a horse-drawn carriage, fish scales, and a rare cancer that transformed our understanding of allergies.

In this episode, Dr. Adam J. Brown concludes the asthma series by telling the remarkable story of IgE—the antibody at the center of allergic disease. We begin with a mysterious 1919 case in which a man seemingly developed a horse allergy after a blood transfusion, then follow the pioneering experiments that revealed allergic sensitivity could be transferred through plasma.

From there, we piece together the puzzle of allergy by connecting IgE, mast cells, and histamine. You'll discover how allergen-specific IgE triggers the release of histamine, why this pathway is responsible for many allergic reactions and asthma attacks, and how these discoveries paved the way for anti-IgE therapies like omalizumab—changing the treatment of allergic asthma, chronic hives, food allergies, and more.
