Beyond Boundaries: How Agnès Azimzadeh's Xenotransplantation Research Is Bridging the Organ Gap

Pioneering the future of organ transplantation through innovative cross-species research

Xenotransplantation Immunology Scientific Legacy

The Scientist Who Dreamed of Infinite Organs

Imagine a world where no one dies waiting for an organ transplant. This vision drives xenotransplantation—the science of transplanting animal organs into humans—a field that lost one of its brightest stars on March 15, 2021, when Dr. Agnès Marie Azimzadeh passed away after a courageous battle with cancer 1 .

The Waiting Crisis

Every day, 17 people in the US die waiting for an organ transplant. Dr. Azimzadeh's work aimed to eliminate this tragic statistic.

30+ Years of Research

Over three decades dedicated to unraveling complex immune responses in cross-species transplantation 1 .
