Dr. Adnane Sellam joined Laval University in August 2013 as an assistant professor at the School of Medicine (Department of Microbiology-Infectious Disease and Immunology) and new member of the CHU de Québec research center and its vibrant community of researchers. As a principal investigator, Dr Sellam is affiliated to the Centre de Recherche en Infectiologie (CRI-CHUL) and the centre de recherche en données massives de l’Université Laval (CRDM-UL). Dr Sellam held a Ph.D. from University of Angers (France) and undertook two productive postdoctoral trainings at Université de Montréal and University McGill/NRC Canada. Dr. Sellam is an expert on Systems biology and genomics, applied to fungal pathogens. His research has been funded by different recognized provincial (CQDM, FRQS, CHUQ foundation, Merck-U Laval) and federal (NSERC, CFI) funding organisms.
Candida albicans is an opportunistic pathogen responsible for various non-life-threatening infections, such as oral thrush and vaginitis. This pathogen is also a major cause of morbidity and mortality in bloodstream infections, especially in immunosuppressed individuals. The arsenal of clinically active antifungal compounds is limited, because of the eukaryotic nature of this yeast, which makes it like its human host. In addition, many cases of clinical resistance to all anti-Candida drugs have been reported. Currently, the pipeline of pharmaceutical companies for new drugs targeting C. albicans infections is completely dry. Thus, discovery of new drugs is of utmost urgency to fight C. albicans infections. The purpose of Dr. Sellam’s research is to gain a deep knowledge on mechanisms that control the virulence of C. albicans. This will lead to identification of proteins or biological processes that are required for the establishment of the infection. Screens of chemical libraries will identify bioactive molecules that inhibit these proteins, and consequently limit the infections.
The main objective of my research program is to decipher C. albicans regulatory circuits that control adaptation to hypoxia and cell size homeostasis. These biological processes are both intimately linked to C. albicans virulence. Dr. Sellam’s team is also screening different chemical libraries to find small molecules inhibiting filamentation and biofilm formation, which are key manifestations of C. albicans pathogenicity.
