    Författare :George Makau Nduva; Systemvirologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; HIV-1; phylogenetics; risk groups; transmission dynamics;

    Sammanfattning : With a national prevalence of 4.9% in the adult population, the HIV-1 epidemic in Kenya is the fifth largest in the world. LÄS MER

  2. 27. From Physicochemical Features to Interdependency Networks : A Monte Carlo Approach to Modeling HIV-1 Resistome and Post-translational Modifications

    Författare :Marcin Kierczak; Jan Komorowski; Anna Tramontano; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bioinformatics; HIV-1; resistome analysis; drug resistance; predicting PTMs; molecular interdependency networks; MCFS-ID; feature selection; interactome; machine-learning; rough sets; Bioinformatics; Bioinformatik; Computer Science; datavetenskap; Biology; with specialization in structural biology; biologi; med inriktning mot strukturbiologi;

    Sammanfattning : The availability of new technologies supplied life scientists with large amounts of experimental data. The data sets are large not only in terms of the number of observations, but also in terms of the number of recorded features. LÄS MER

  3. 28. Studies on Potency and breadth of HIV-1, HIV-2 and SIV neutralizing antibody responses

    Författare :Gülsen Özkaya Sahin; Avdelningen för medicinsk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; HIV-1; HIV-2; SIV; envelope; neutralizing antibody; breadth; potency; IgG; IgA; complement; antibody-dependent complement-mediated inactivation; virus evolution; diversity; divergence;

    Sammanfattning : Even though the relative contribution of neutralizing antibodies (Nab) to prevent progression to AIDS during HIV-1 infection is still unclear, the induction of broadly NAb directed against HIV-1 through vaccination is considered to represent an important goal for the development of HIV-1 vaccines. Factors contributing to the induction of NAb may include the strength and duration of antigenic stimulation, the preservation of CD4+ T and B cells, the conformation of the HIV-1 envelope glycoprotein complex (Env), and the evolution of Env during infection.

  4. 29. Recombinant CXCR4/CCR5 hybrid receptors as tools for studies of HIV-1 receptor usage

    Författare :Liselotte Antonsson; Drug Target Discovery; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicin människa och djur ; evolution; pathogenesis; cerebrospinal fluid; Medicine human and vertebrates ; TAK-779; RANTES; CXCR4; CCR5; coreceptor; GPCR; HIV-1;

    Sammanfattning : The chemokine receptors CCR5 and CXCR4 are required, together with CD4, for the entry of HIV-1 into target cells. CCR5 using HIV-1 dominates during transmission and the asymptomatic phase of infection. During progression, virus phenotypes with the ability to use CXCR4 emerge in about 50% of infected individuals.

  5. 30. Intrahost evolution of HIV-1 phenotypes

    Författare :Marie Borggren; Avdelningen för medicinsk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : HIV-1 evolves constantly within an infected individual, due to its mutation-prone viral enzyme, high viral turnover and pressure from the host immune system. Therefore, viruses isolated at different time points from the same individual are never exactly the same and, accordingly, rarely function the same way. LÄS MER
