image 1 IVPC FA group   Retroviruses exploit cellular machineries to propagate. In the last decade, impressive similarities have been observed in the generation and dissemination in the host cells of retroviruses and small cellular vesicles known as exosomes (Izquierdo-Useros, Puertas et al. 2011, Meckes and Raab-Traub 2011). These cellular vesicles are thought to facilitate intercellular communication processes and mediate immune functions (Simons and Raposo 2009). They are issued from internal endosome-derived membranes and are secreted by cells under normal or pathological condition (infection, cancer). Ranging from 30 to 150 nm in size, exosomes can incorporate proteins, microRNA (miRNA), mRNA, mtDNA, DNA and retrotransposons; they can mask viruses/viral components from immune surveillance, and transfer cargo between cells. They can contribute to the horizontal transfer of oncogenes (Al-Nedawi, Meehan et al. 2008, Demory Beckler, Higginbotham et al. 2013) or pathogenic elements such as virus elements (Ramakrishnaiah, Thumann et al. 2013, Nour and Modis 2014) or prion (Fevrier, Vilette, Archer et al. 2004), inducing deregulation of the recipient cell and /or propagation of the disease.

Our research focus on the transfer of viral elements (oncogenic viral protein, RNA) via microvesicles from infected/transformed cells to naïve cells, and their impact on the cellular environment (immune regulation, cell transformation).  The JSRV retrovirus being an oncogenic virus, we study the capacity of the oncogenic viral protein to be transferred to naïve cells via microvesicles and/or exosomes and to modulate neighboring cells behavior. Having a long experience in lung epithelial cells models, we question the impact of exosomes/microvesicles on bronchioli and alveolar cells homeostasis, in the context of infection, and investigate their involvement in lung pathology development and maintenance.

The obviously broad biological and medical implications of microvesicles make them a significant and exciting area of research with potential high impact on our understanding of pathogenesis within the infected individual. Therefore understanding the interplay between viruses and microvesicles may contribute to the development of novel therapeutics or vaccines to control viral infections and prevent development of pathologies.
