Catherine Blish

Catherine Blish is a translational immunologist and professor at Stanford University. Her lab works on clinical immunology and focuses primarily on the role of the innate immune system in fighting infectious diseases like HIV, dengue fever, and influenza. Her immune cell biology work characterizes the biology and action of Natural Killer (NK) cells and macrophages.

For her previous and ongoing work fighting HIV/AIDS, Blish was awarded the 2018 Avant-Garde Award from the National Institute on Drug Abuse.

Contributions to immunology

Natural Killer cell immune memory A key concept in the adaptive immune system, and the foundational science behind vaccines, is that some elements of the immune system recognizes antigens it has seen before in a process called as immunological memory. Dr. Blish and colleagues have identified a potential mechanism through which NK cells may also display immune memory. This is unusual and shifts the accepted paradigm because NK cells are typically considered part of the innate immune system, not the adaptive immune system. Dr. Blish and colleagues demonstrate antigen-specific recognition, and memory of viruses and viral antigens by NK cells in mice and primates.

COVID-19 In 2020, Dr. Blish's lab pivoted to work on SARS-CoV-2 due to the COVID-19 pandemic. With colleagues, the Blish lab is scrutinizing ways chloroquine interferes with the viral life cycle.
