Profile

The Ward lab uses electron microscopy to image viral and malarial antigens in complex with neutralizing antibodies and the structural data are then used to improve antibody-based therapies and rationally design vaccines. The Ward lab has published extensively on cryoEM studies of HIV envelope glycoprotein, including the first high-resolution structure of the soluble SOSIP trimer. This previously elusive target galvanized HIV subunit vaccine efforts, one of which is began human clinical trials 2020 as part of a large international effort. The Ward lab also solved the structure of a human coronavirus spike protein in 2016, which enabled structure-based vaccine design to create stabilized, pre-fusion subunit vaccine candidates SARS CoV-2 spike proteins. These '2P' mutations are being used to develop prefusion subunit vaccines for SARS-CoV-2 (COVID-19). In 2018 the Ward lab developed a transformative EM imaging method to assess polyclonal antibody responses to spike-based subunit vaccines that now enables rapid iteration of vaccine design and implementation. We most recently demonstrated that this methodology can yield atomic-level details and antibodies can be sequenced directly from structural data, circumventing the expensive and laborious process of B cell isolation and cloning approaches currently employed to generate monoclonal antibodies.
