Hepatitis E virus (HEV) infection is a major public health problem that affects more than20 million people and kills approximately 70,000 worldwide each year. HEV is the leadingcause of acute viral hepatitis in the world. In France, the seroprevalance of HEV is 22.4% inthe general population. This virus is transmitted by fecal-oral route or by consumption ofundercooked contaminated meat. Very recently, we have described an efficient cell culturesystem to amplify HEV. This system represents a unique tool for characterizing the variousstages of the infectious HEV lifecycle that are very poorly understood to date. As part of mythesis, I focused on the ORF2 capsid protein which is the structural unit of viral particles andis therefore a central player in the HEV lifecycle. ORF2 is a 660 amino acids protein thatcontains a signal peptide and three potential N-glycosylation sites (N1, N2 and N3). My workaimed to identify the role of the ORF2 N-glycosylation in the HEV lifecycle. Our resultsrevealed that the ORF2 protein is N-glycosylated on the N1 and N3 sites, whereas the N2 siteis not N-glycosylated. Also, the N-glycosylation has no significant relevance neither for thestability, oligomerization, antibody recognition of the ORF2 protein nor for viral assemblyand viral infectivity. We also revealed that, the ORF2 protein is translocated into the nucleusof infected cells, independently of N-glycosylation. We identified for the first time afunctional nuclear localization signal (NLS) located at the N-terminus of the ORF2 proteinthat interacts probably with the importin alpha1. Surprisingly, this NLS regulates both nuclearimport and endoplasmic reticulum translocation of the ORF2 protein. Finally, wedemonstrated that, the ORF2 protein possesses three nuclear export signals (NES) located atits C-terminus. The ORF2 protein interacts with the exportin1 and is exported from the cellnuclei. This interaction drives the ORF2 protein from the nucleus to the cytoplasm of theinfected cells. Hence, this study led to new insights into the molecular mechanisms of theORF2 protein and could help to the design of novel antiviral strategies against HEV

Hepatitis E virus (HEV) infection is a major public health problem, affecting an estimated 100 million people and killing 100,000 every year worldwide. HEV is the leading cause of acute hepatitis worldwide. In France, seroprevalence is 22.4%. This virus is transmitted via the feco-oral route, or by eating contaminated undercooked meat. During my thesis, I focused on the ORF2 capsid protein, which is the structural unit of viral particles and a central player in the HEV lifecycle. ORF2 is a 660 amino acid protein with an N-terminal signal peptide and three potential N-glycosylation sites. During its lifecycle, HEV produces at least three forms of its capsid protein: (i) the ORF2g (for glycosylated) form and (ii) the ORF2c (for cleaved) form, abbreviated ORF2g/c, which are glycosylated forms and massively secreted in culture supernatants or serum from infected patients, and (iii) the ORF2i (for infectious) form, which is not glycosylated and is associated with viral particles.As part of my thesis work, I studied the mechanisms of proteolytic maturation and intracellular trafficking of the ORF2 protein. More specifically, I first showed that ORF2 is imported into the nucleus of infected cells via an Importin-alpha1-dependent mechanism, thanks to an arginine-rich motif located at the N-terminus of ORF2 and named ARM. The ORF2 protein is then exported to the cytoplasm via a CRM1 exportin-dependent mechanism, thanks to three nuclear export sites (NES9, NES10 and NES12) that we have identified in the ORF2 sequence. I have also shown that nucleocytoplasmic trafficking of ORF2 probably regulates the expression of certain antiviral immunity genes in the early stages of infection.Secondly, I participated in the identification and characterization of HEV viral factories. We have shown that the viral proteins ORF1, ORF2 and ORF3, as well as viral RNA, are enriched in vesicular and tubular structures located in the perinuclear regions of infected cells. We have shown that these structures are also enriched in markers of the endosomal recycling compartment (ERC), such as Rab11 and CD71, indicating that HEV viral factories probably derive from the ERC. By performing Rab11 silencing experiments with siRNAs, we confirmed the importance of the ERC in the production of HEV viral particles. Thirdly, I demonstrated that the ORF2i protein, which is associated with the membranes of the secretion pathway, is addressed to viral factories by a mechanism involving the AP-1 adaptor complex.In a fourth step, I characterized the proteolytic maturation mechanisms of the ORF2g/c and ORF2i forms. I showed that furin, a proproprotein convertase of the secretory pathway, is involved in the proteolytic maturation of ORF2g/c glycoproteins. I have also shown that presenilin, which is the catalytic subunit of the macro-complex Gamma-secretase, is involved in the proteolytic maturation of the ORF2i form. Interestingly, I have shown that pharmacological inhibition of presenilin drastically reduces viral infectivity in human hepatocarcinoma lines and in primary human hepatocytes. These data suggest that pharmacological inhibition of presenilin represents a promising antiviral strategy. In conclusion, the results obtained during my thesis provide a better understanding of the mechanisms of subcellular addressing and proteolytic maturation of the ORF2 capsid protein, and pave the way for the development of new therapies to combat HEV

Insect-derived baculoviruses have been used extensively as a safe and versatile research model for transgenic protein expression. Preclinical studies have revealed the promising potential of Baculoviruses as a delivery vector for a variety of therapeutic applications, including vaccination, tissue engineering and cancer treatments. Coronaviruses are enveloped viruses containing linear, non-segmented ribonucleic acid. Human coronavirus NL63 was first discovered in the Netherlands in January 2004, where a 7-month-old girl presented with an acute respiratory tract infection that was later established to predominantly infect infants, the elderly and immunocompromised individuals. In addition to the known non-structural and structural proteins of coronaviruses, an accessory protein known as open reading frame 3 which is conserved in the Coronaviridae family has not been extensively researched. Open reading frame 3 encodes a putative membrane-bound protein. This study cloned the open reading frame 3 viral gene of 741 base pairs into the baculovirus expression construct via competent bacterial cell lines. Open reading frame 3-Baculovirus particles were generated in Spodoptera frugiperda insect cells. Recombinant cells containing the viral protein gene were used to infect healthy Spodoptera frugiperda 9 cells at varying ratios of multiplicity of infection over a fixed time-course. The open reading frame 3 viral protein was not detected by quantification methods at a molecular weight of 26 kilo Dalton, due to polyclonal antibody degradation.
