Expertises

The long-term goal of my research program is to better understand molecular mechanisms of interactions between animal viruses and their hosts in order to develop new strategies for effective control of viral infections. In my laboratory, we study molecular mechanisms of virus-host interactions of different viruses: the porcine reproductive and respiratory syndrome virus (PRRSV), the porcine epidemic diarrhea virus (PEDV, a coronavirus), the Aleutian mink disease virus (AMDV, a parvovirus), the porcine influenza virus, various arboviruses (Zika, dengue, etc.). Additionally, we are interested in studying viral pathogens that infect the honeybees (virome studies). Host-virus interactions are highly dynamic and may involve multiprotein complexes. My group is using cutting-edge molecular biology, microscopy, proteomics, classical and molecular virology approaches to decipher the interplay of the key molecular factors of the virus infection that contribute to the unique pathogenesis of the animal viruses that are  important for human and animal health. I believe that science popularization plays an important role in enhancing public service, promotes scientific literacy and awareness of global health.

Studies on Molecular Mechanisms of HostPathogen Interactions of Nidoviruses of Veterinary Importance Projet de recherche au Canada / 2017 - 2022

Lead researcher : Levon Abrahamyan

The proposed program will advance fundamental knowledge about the molecular
mechanisms of virus-host interactions of important animal RNA viruses united in the Nidovirales
order. The porcine reproductive and respiratory syndrome virus (PRRSV) and the porcine
epidemic diarrhea virus (PEDV) are nidoviruses responsible for severe agricultural economic losses
and considered to be the primary emerging livestock pathogens in Canada and globally. Although
the hosts have developed multiple immune defense systems that could fend off viral infections and
control viral disease, viruses have evolved to invade host cells and hijack the host cellular machinery
in order to survive and replicate. Thus, understanding how viruses attach and enter target cells, how
viruses establish a fine-tuned balance between host and virus genome translation, how viruses traffic
their genomes and proteins to the sites of virions assembly, and modulate host innate response, will
uncover novel targets for antiviral therapies and control viral spread.
