Infectious diseases research encompasses basic studies on viruses, bacteria and host immune responses.
Dr Sergey Nejentsev’s group investigates genetic and functional mechanisms of susceptibility to infection. The group is conducting large genome-wide association studies aiming to identify human variants that control immune responses to M. tuberculosis infection and predispose to pulmonary TB. The group also studies patients with primary immunodeficiencies using whole exome sequencing to discover new causative mutations, followed by detailed functional analyses of the affected cellular pathways.
Professor Sharon Peacock’s group aims to introduce high-throughput whole genome sequencing technologies into diagnostic and public health microbiology for outbreak investigation and to optimise antimicrobial therapy of individual patients. She works in close collaboration with the Wellcome Trust Sanger Institute and the Health Protection Agency.
Professor John Sinclair’s group studies how human cytomegalovirus (HCMV) persists in healthy individuals studying cellular factors which control virus latency and reactivation. Dr Wills’ group, with Professor Sissons, study the control of HCMV infection by the immune system. In collaboration, their work on latent carriage of the virus and host immune responses to latent infection has now identified changes in the latently infected cells which can act as targets for novel chemotherapeutic and immunotherapeutic strategies with an aim to clearing latent infection in some clinical settings.
Professor Andrew Lever’s group studies retroviruses, including structural and molecular studies of RNA and RNA:protein interactions involved in genome encapsidation and the development of gene vectors. He and Dr Desselberger are investigating rotavirus RNA structures involved in encapsidating the viral genome and which host cell proteins or organelles may interact with the virus and be involved in viral assembly.
Dr Lydia Drumright’s group takes a multidisciplinary approach to infectious disease epidemiology integrating classical and molecular epidemiology with clinical informatics, statistical and mathematical modelling, and behavioural and environmental sciences. This systems-level way of thinking helps to maximise our understanding of how infectious diseases are transmitted, resulting in more effective interventions. Recent work includes the characterisation of norovirus transmission dynamics within healthcare settings, and the use of electronic hospital data for infectious disease surveillance.
Dr Yorgo Modis’s groups goal is to gain a mechanistic understanding at the molecular level of how important pathogens interact with their host cells during infection. We seek to understand the following major questions: (1) How do enveloped viruses assemble and recognize host cells? (2) How do enveloped viruses deliver their genome into the cytoplasm? (3) What are the evolutionary origins of the genes that drive virus entry? (4) How are innate immune responses to microbial nucleic acids generated, amplified and regulated? To answer these questions, we are employing a diverse set of complementary biophysical, biochemical and cell biological approaches. By integrating approaches across scales (in space and time), we envision moving towards a structure-based understanding of biological processes at the cellular level. Each of our projects has important potential applications in global health.
