Definitions
- the present invention relates to a vaccine in polyvalent units against viruses of the family of Flaviviridiae and in particular against flaviviruses such as Dengue viruses, yellow fever, Japanese encephalitis, or other Flaviviridiae, or "Flavi- like "such as hepatitis C virus, and mixtures thereof (18)
- Flaviviruses are viruses of the arbovirus family (old group B arboviruses). They are vertebrate viruses generally transmitted by hematophagous arthropods (mosquitoes, ticks, sandflies), in which they multiply before transmission. so intervene an arthropod vertebrate and a reservoir Some arboviruses can affect humans and induce pathologies, the arboviruses which are found especially in tropical regions If there has been a vaccine against yellow fever since 1930, or more recently against encephalitis Japanese and tick, the other flaviviruses currently have no vaccine, this is particularly the case for Dengue
- the virus responsible for Dengue spreads concomitantly with its vector, the mosquito Aedes aegypti
- the disease is characterized by a high fever accompanied by headache, nausea and joint and muscle pain which disappears after a few days Symptoms may, however, intensify leading to hemorrhagic manifestations which are sometimes fatal when the disease is associated with hypovolemic shock, especially in children
- the agent responsible for Dengue is an RNA flavivirus from the Flavivmdae family, just like the yellow fever virus or that of Japanese encephalitis We know 4 serotypes Dengue hemorrhagic fever could be a consequence of a poorly understood immunological phenomenon, probably involving a cascade of e cytokines linked to the induction of cytotoxic cellular immunity which may result from sequential infection by several serotypes.
- a first vaccine against Dengue is currently being tested. It is a vaccine based on 4 living serotypes, attenuated by successive passages of the virus in cell culture.
- the major drawback of this type of vaccine is the possibility of attenuated viruses reversing towards virulence, by genetic reversion or recombination between genomes. It also presents a potential risk for newborns and for immunocompromised people. In addition, some children vaccinated with the tetravalent vaccine seem not to be protected against the 4 serotypes.
- the structure of the genome is the amino acid sequence of the Dengue virus, in particular that of serotype 2, has been described by
- the Dengue virus is an enveloped RNA virus of about 50 nanometers. Like the yellow fever virus, all viral proteins are coded by a segment of approximately 10 ⁇ e kilobases, the structure of which is as follows:
- the structural proteins are C (capsids), pre-matrix / matrix (preM / M) and the envelope protein (E).
- proteins are encoded by the 5 'fragment, followed by non-structural proteins (NS) encoded by the rest of the genome. Proteins are produced by a proteolytic process induced by cellular signalase and other cellular and viral proteinases.
- the envelope glycoprotein (E) is the majority surface protein.
- the structure of sterotype 1 has been described by Mason et al. (2).
- Serotype 2 has been described in (1), and is the best known of the 4 serotypes; type 3 serotype has been described by Osatomi K. al. (3) and the type 4 serotype has been described by Zhao et al., (4).
- baculoviruses are very attractive for this type of production thanks to the high level of genetic expression they can achieve and for their absence of pathogenicity for humans.
- Baculovirus has already been used for the expression of flavivirus proteins. Dengue serotype 1 (5), Dengue serotype 4 (DEN-4) (6) and serotype 2 (DEN-2) have been described. (7), (8), (9) and serotypes 2 and 3 have been described by C. Delenda et al. (10).
- sequence homology between the 4 genomes corresponding to the 4 serotypes of the virus is relatively large; by way of example, protein E of these viruses has a percentage of homology as presented in table 1 below:
