Personal Statement

Keywords: Vaccinology, Immunomics,  Molecular mechanisms of dengue immunity and pathogenicity

Research Summary. The research interest of Dr. Marques is designing novel vaccine strategies, immunotherapies, diagnostic markers and disease surveillance tools based on  human samples from well characterized cohorts. The strategy he uses is based on the development of detailed T and B cell epitopes maps and the characterization of innate immune response induced by the pathogenic agents. The laboratory apply a combination of computational technologies, high throughput immune assays in human samples. Using this information we explore patterns correlated either with immunity or pathogenicity and design novel antigen formulations containing selected epitopes, adjuvants and adequate delivery methods. Currently we are applying this strategy to study Zika, Dengue, yellow fever, HIV among other agents.  Dr, Marques is also the inventor of several vaccine and diagnostic technologies.  Some of his technologies are currently licensed by leading pharmaceutical companies.
