Antibody response against selected epitopes in the HIV-1 envelope gp41 ectodoma...
Marcelino, Rute; Gramacho, Filipa; Martin, Francisco; Brogueira, Pedro; Janeiro, Nuno; Afonso, Claudia; Badura, Robert; Valadas, Emília; Mansinho, KamalThe ectodomain of gp41 is the target of potent binding and neutralizing antibodies (NAbs) and is being explored in new strategies for antibody-based HIV vaccines. Previous studies have suggested that the W164A-3S (3S) and EC26-2A4 (EC26) peptides located in the gp41 ectodomain may be potential HIV vaccine candidates. We assessed 3S- and EC26-specific binding antibody responses and related neutralizing activity ...
Epidemic history of hepatitis C virus genotypes and subtypes in Portugal
C., Palladino,; Ifeanyi Jude, Ezeonwumelu,; Marcelino, Rute; Verónica, Briz,; Inês, Moranguinho,; Fátima L., Serejo,; José Fernando, Velosa,Any successful strategy to prevent and control HCV infection requires an understanding of the epidemic behaviour among the different genotypes. Here, we performed the first characterization of the epidemic history and transmission dynamics of HCV subtypes in Portugal. Direct sequencing of NS5B was performed on 230 direct-acting antiviral drugs (DAA)-treatment naïve patients in Lisbon. Phylogenetic analysis was ...
