Katalin Kariko


Katalin Karikó is a Hungarian biochemist who specializes in RNA-mediated mechanisms. Her research has been the development of vitro-transcribed mRNA for protein therapies. She currently serves as the Senior Vice President at BioNTech RNA Pharmaceuticals.
Karikó's work includes scientific research of RNA-mediated immune activation resulting in the co-discovery of the nucleoside modifications that suppress the immunogenicity of RNA. This is seen as expanding the therapeutic potential of mRNA. She holds patents granted in the United States for application of non-immunogenic, nucleoside-modified RNA. She co-founded and served as CEO of RNARx from 2006-2013.. Katalin Karikó is the mother of 2-time Olympic Gold Medalist Susan Francia.

Early life and education

Kariko grew up in the Hungarian town of Kisujszallas where she attended Móricz Zsigmond Református Gimnázium. After earning her Ph.D., Karikó continued her research and postdoctoral studies at the Institute of Biochemistry, Biological Research Centre, the Temple University Department of Biochemistry, and the Uniformed Services University of the Health Science. While serving as postdoctoral fellow at Temple University in Philadelphia, Karikó participated in a clinical trial in which patients with AIDS, hematological diseases and chronic fatigue were treated with dsRNA. At the time, this was considered groundbreaking research as the molecular mechanism of interferon induction by dsRNA was not known, but the antineoplastic effects of interferon were well documented.

Career

In 1990, while a Professor at the University of Pennsylvania, Karikó submitted her first grant application in which she proposed to establish mRNA-based gene therapy, Ever since, mRNA-based therapy has been Karikó’s primary research interest. Karikó served for nearly 25 years as a Professor at the University of Pennsylvania Medical School.
In 2012, Karikó and Drew Weissman, an immunologist at the University of Pennsylvania, received a patent for the use of several modified nucleosides to reduce the antiviral immune response to mRNA and they founded a small company. Soon after, UPenn sold the intellectual property license to Gary Dahl, the head of a lab supply company that eventually became Cellscript. Weeks later, Flagship Pioneering, the venture capital company who was and still is backing Moderna, contacted her in hopes of licensing the patent. All Karikó said was “we don’t have it.” In early 2013, Karikó heard of Moderna’s $240 million deal with AstraZeneca to develop a VEGF mRNA. Karikó realized she would not get a chance to apply her experience with mRNA at UPenn and took her role as Senior Vice President at BioNTech RNA Pharmaceuticals.
Her research and specializations include Messenger RNA-based gene therapy, RNA-induced immune reactions, molecular bases of ischemic tolerance and treatment of brain ischemia.

Scientific contributions

The work and research of Karikó has contributed to BioNTech’s effort to create immune cells that produce vaccine antigens — Karikó’s research revealed the ability to leverage the antiviral response to mRNA to give their cancer vaccines an extra boost in defense against tumors.
