Research Summary:

The human immune system employs many different strategies when attacking an invading pathogen. One of these strategies is the creation of antibodies—molecular tags that direct immune cells toward antigens such as viruses. Antibodies can be created to target any part of an invading virus, including proteins on the viral surface that are critical for entry into our healthy cells. Some of these surface proteins are glycoprotein, or long chains of amino acids with carbohydrate groups attached. Antibodies that target glycoproteins can inhibit a virus’ ability to enter cells, effectively neutralizing the virus; these types of antibodies are called “neutralizing antibodies”.

Katie Doores, DPhil, studies the biology and co-evolution of viral surface glycoproteins and neutralizing antibodies. Glycoproteins on the surface of HIV-1 were originally thought to shield the virus from the immune system; however, Doores showed that these glycoproteins are, instead, the targets of neutralizing antibodies. In the process of this discovery, she revealed that an HIV glycoprotein produced for clinical trials, gp120, differed significantly from the naturally occurring protein, explaining why past immunization regimes may have failed.

In 2020, Doores transitioned her work to studying antibody responses to SARS-CoV-2 by defining the kinetics, magnitude, and durability of the antibody response. Through a national virology consortium, called genotype to phenotype (G2P-UK), Doores provided important guidance to UK policy makers during the pandemic. In addition to her work on HIV and SARS-CoV-2, she has identified and characterized neutralizing antibodies to many other emerging zoonotic viruses, which will aid in the development of glycoprotein vaccines for Hantaan virus, Rift Valley Fever Virus, New World Arenaviruses, including Machupo and Junin virus.

"My lab studies how our immune system responds to viral infections to inform the development of vaccines against biomedically important viruses. Through this research we aim to aid in our preparedness for potential future pandemics."
