Résumé des résultats (Abstract) (Anglais)

There is urgent need for HIV vaccines with high protective efficacy, low cost and simple immunisation schedule. Aim of this project is to assess in the macaque model the efficacy of
(i) new vaccine candidates (lipid-DNA; single cycle lentiviral vector; recombinant S.gordonii) made by our consortium;
(ii) prime-boost vaccination strategies with/without adjuvants (GM-CSF, TNF-alpha, C pG motifs) and
(iii) route of vaccine application (via the tonsils vs. parenteral) for inducing immunity and protect ion to mucosal challenge.

We also address to vaccine biology at dendritic cell level. With the oral route we target dendritic cells that are numerous at this site and mature them with adjuvants. Thus, we expect to see an enhanced immunity, a low viral set point (undetectable virus by infectious unit and RNA assays) or at least a reduction of viral load (100 RNA copies/ml of plasma), clinical well being and normal CD4 counts and function.
