Research area of the Unit
Our unit studies the basis of human genetic susceptibility to major mosquito-borne infections, malaria and dengue. We aim not only to identify new genes governing different infection outcomes, such as disease presentation and transmissibility, but also to understand how the different alleles of these genes affect the trait. Identifying key factors underlying an outcome of interest becomes increasingly problematic as the number of variables increases and they do not work independently. We are working on creating a mathematical platform to exhaustively explore retrospective and prospective biological and epidemiological data sets and to generate hypotheses that will provide the framework for the development of predictive models of disease risk. We will learn from experimental datasets of biomolecular interactions from a cellular functional genomics model. This model allows us to integrate interactome data with genome wide genetic study.
Contribution to the programme
The group will contribute to the human genetics part of the programme. There is increasing evidence that pathogens adhere to predictions derived from evolutionary theory, thereby enabling identification of factors for targeting in the development of public health intervention strategies. Thus, a better understanding of the epidemiology of pathogens can be gained through an appreciation of adaptations that govern pathogen transmission from man, or the vertebrate host for anthropozoonotic diseases, to the invertebrate vector. Hence, we can combat certain pathogens, even those that are endemic, by eliminating the source of infection. This is particularly true for emerging diseases. It is therefore necessary to identify, in the infectious disease reservoir, those individuals responsible for transmission (often asymptomatic), and according to the pathogen in question, establish the role played by man.
They have established strong collaboration with several countries including Thailand, Cambodia, Laos, Vietnam, India, Senegal, Madagascar, French Guiana, Brazil, Argentina, Peru and Cuba.
