Giants in History: Teruko Ishizaka

The immunologists who studied allergic reactions 

Teruko Ishizaka (28 September 1926 - 04 June 2019)

Japan

Husband and wife team, Kimishige (3 December 1925 – 6 July 2018) and Teruko Ishizaka (28 September 1926 – 4 June 2019) discovered the antibody class Immunoglobulin E (IgE) that triggers allergic reactions. They also discovered that IgE antibodies attach to white blood cells, known as mast cells, releasing histamine, which causes allergic reactions. A pioneer of her time, Teruko earned a M.D. and Ph.D. in medical science from the Tokyo’s Women’s Medical University and from the University of Tokyo respectively. Teruko was the head of the Division of Allergy at the La Jolla Institute for Immunology, while Kimishige was the first scientific director of the institute. The Ishizakas supported young scientists and encouraged a collaborative spirit among the researchers at the institute. On retirement, the couple moved to Teruko’s hometown, Yamagata, Japan, where Kimishige was a specially invited professor at Yamagata University. Throughout their careers, the duo co-authored over 100 papers and reviews on allergy-related topics and won several awards. (Photo courtesy of Yamagata University, Faculty of Medicine)
