Professor Martin Cranage is Emeritus Professor of Molecular Vaccinology at St George’s, University of London.
He works on understanding how experimental vaccines and other preventative approaches against HIV interact and stimulate the body’s immune responses. His specific focus is on the prevention of HIV transmission at the body's mucosal surfaces, including the vagina and rectum. He is a specialist in non-human primate immunology and vaccine challenge models.
Professor Cranage’s broad research interest lies at the interface between microbiology, in particular virology, and immunology. His research has involved the identification and characterisation of putative vaccine components, the analysis of cellular and humoral immune responses in vaccination and infection, virus pathogenesis and the development of novel diagnostic assays for a number of clinically important microorganisms.
In the 1990s Professor Cranage and his team, as part of the Medical Research Council AIDS Directed Programme, pioneered a rectal challenge model for HIV vaccine evaluation and investigated protective mechanisms elicited by inactivated virus, live attenuated viruses, virus vectors including recombinant Modified Vaccinia Vius Ankara and first-generation replication defective adenoviruses encoding SIV trangenes both alone or in combination with DNA priming (heterologous prime boost). He was actively involved in the discovery of the role of host cell proteins in vaccine protection conferred with inactivated vaccines, an interest that he has continued to pursue. Recently he convened a series of on-going international “think tank” workshops (4C programme) to identify pathways for continued research in this area.
Over the past decade at St George’s, Professor Cranage has worked closely with Professor Robin Shattock, at Imperial College London, and a large multi-national, multi-disciplinary consortium as a principal investigator on a Bill and Melinda Gates / Wellcome Trust funded Grand Challenge in Global Health programme: "Novel Antigen Design and Delivery for Mucosal Protection Against HIV-1 Infection". This afforded the opportunity to undertake highly novel parallel investigations in animal model and clinical trials ("para-clinical testing") facilitating the calibration and validation of the animal model for vaccine efficacy against virus challenge. This new paradigm reduces over-reliance on animal models and ensures that they are used to maximum benefit.
Professor Cranage as a co-principal investigator on an NIH U19 project and in collaboration with Dr Sally Sharpe at HPE, Porton demonstrated, in a model system, the utility of topical pre-exposure to tenofovir, an approved antiretroviral drug. This approach is now being evaluated in the clinic (topical pre-exposure prophylaxis).
Professor Cranage has continued to investigate mechanisms of immunity operating following vaccination with live attenuated retroviruses. Through collaboration with teams at the National Institute for Biological Standards and Control, UK led by Dr Neil Almond, the University of Amsterdam, led by Professor Ben Berkhout and University College London, led by Professor Greg Towers, including funding from the International AIDS Vaccine Initiative (IAVI), Professor Cranage’s group have investigated detailed T cell memory responses using state of the art flow cytometry methodologies and a highly novel replication conditional mutant of SIV.
Professor Cranage joined St George’s in October 2002 as Professor of Molecular Vaccinology. Prior to this he was a scientific leader at the government's Centre for Applied Microbiology and Research at Porton Down, Salisbury, where he and his team established and developed models of HIV infection and investigated a range of vaccine approaches to prevent infection.
Professor Cranage graduated from Newcastle University in microbiology in 1975 where he went on to complete a PhD on the immunology of respiratory syncytial virus infection in infants.
Following his PhD training, he took up a five year postdoctoral post at the University of Cambridge, in the Department of Pathology in the laboratory of Professor Robin Coombs, working on the development of novel rapid viral diagnostic assays. Following this he became the John Lucas Walker Senior Student in the Division of Virology based in the laboratory of Professor Tony Minson investigating cloning, expression and characterisation of glycoproteins of human cytomegalovirus. This work was one of the first demonstrations of reverse vaccinology, where putative vaccine components were cloned and expressed their ability to react with and elicit virus neutralising antibodies.
