  7. 25. Biological correlates of HIV-1 heterosexual transmission

    Author : José Ramón Fiore; Karolinska Institutet; Karolinska Institutet; []
    Keywords : HIV-1 sexual transmission HIV-1 biological phenotypelneutralizing antibodies V3 loop antibodies infectiousness disease progression drug resistance;

    Abstract : HIV-1 infection is a sexually transmitted disease but HIV transmission efficiency by sexual contacts appears to be highly variable; this is probably due to the influence that several behavioural, clinical and biological factors exert on the transmission event. Here we focused on possible biological correlates of HIV sexual transmission, with emphasis on the host antibody response towards HIV and the virus biological characteristics. READ MORE
