  • Entry inhibitors and Carbosilane dendrimers are potent inhibitors of cell-associated HIV-2 infection
    Publication . Diniz, A. R.; Briz, V.; Borrego, P.; Palladino, C.; Rodés, C.; De la Mata, F. J.; Gómez, R.; Muñoz-Fernández, M. A.; Taveira, N.
    "Pre-exposure prophylaxis with topical microbicides formulated with antiviral agents can prevent HIV-1 acquisition. The ideal microbicide should prevent both cell-free and cell-associated HIV-1 and HIV-2 infections in the vaginal or rectum mucosa. So far, few candidate microbicides have been tested against HIV-2. Previously, we have shown that anionic carbosilane dendrimers 2G-S16 (sulphonate), G2-NF16 (naphthylsulfonated) and G3-S16 (sulphated-end groups) have potent antiviral activity against HIV-1. In this work, we evaluated the activity of these dendrimers and the fusion inhibitors T-1249 and T20 in preventing cell-free and cellassociated HIV-2 infection."

  • Evaluation of an in-house molecular HIV-1 test to assess mother-to-child HIV-1 transmission in Angola (the APEHC cohort)
    Publication . Martin, F.; Palladino, C.; Mateus, R.; Clemente, S.; Gomes, P.; Taveira, N.
    "Mother-to-child-transmission (MTCT) rate has decreased sharply in recent years in most of the sub-Saharan Africa, however 220,000 children acquired HIV-1 in 2014. PCR detection of proviral DNA is the most sensitive method for early infant diagnosis (EID) of HIV-1 infection. Commercial kits are available but they have poor sensitivity with divergent non-B subtypes and high costs (≈30€ per test) which limit their use in resource-limited settings. The HIV-1 epidemic in Angola is driven by highly divergent strains of all group M subtypes, except B, as well as multiple recombinant forms (CRFs and URFs) making EID a challenge in this setting. The aim of this study was to develop and validate a qualitative, inexpensive and sensitive “inhouse” HIV-1 EID assay on heel prick dried blood spots (DBS) from infants of the Hospital da Divina Providência (HDP) in Luanda, Angola and determine the current HIV-1 MTCT rate in the Angolan PErinatal HIV Cohort (APEHC)."
