  2. 1. HIV Persistence and Viral Reservoirs

    Author : Arvid Edén; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; HIV-1; antiretroviral therapy; latency; cerebrospinal fluid; central nervous system; efavirenz; lopinavir; atazanavir; neopterin; viral decay;

    Abstract : Although antiretroviral therapy (ART) can effectively inhibit replication of human immunodeficiency virus type 1 (HIV-1), the virus is able to persist in cellular and anatomical viral reservoirs. Latently infected resting memory CD4+ T-cells are an important cellular reservoir, and the central nervous system (CNS) an important anatomical reservoir for HIV-1 infection. READ MORE

  4. 2. HIV-2 genetic evolution and viral dynamics

    Author : Eleonor Brandin; Karolinska Institutet; Karolinska Institutet; []
    Keywords : HIV-2; antiretroviral treatment; resistance; pathogenesis; co-receptor; neutralization; viral dynamics;

    Abstract : HIV-2 is less pathogenic and less transmissible compared to HIV-1. This is believed to be due to the lower viral load that is seen in HIV-2 infected patients. However, why this lower viral load is seen is not known. In this thesis we have investigated different aspects of HIV-2 in order to understand the pathogenesis of HIV-2 better. READ MORE

  5. 3. Viral dynamics and evolution following primary HIV-1 infection

    Author : Annika C Karlsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : HIV-1; primary infection; diversity; divergence; env; gag; pol; viral load; RNA; DNA; resting CD4 T-lyrnphocytes; antiretroviral resistance; founder virus; latency; PCR; cloning; sequencing;

    Abstract : The knowledge of the early events during primary HIV-1 infection (PER) is of great importance for the understanding of the pathogenesis of HIV-1. A major problem in studies on PHI is the limited amount of data accessible from the early time-points. READ MORE

  6. 4. Simplified Nonsense: New Methods for Interrogating NMD

    Author : Hanna Alalam; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mRNA degradation; metabolic labeling; nonsense-mediated decay; Major protease; SARS-CoV-2;

    Abstract : Nonsense mediated decay (NMD) is a pathway that regulates RNA turnover. Since its discovery, this pathway has been implicated in a variety of cellular processes ranging from differentiation to the restriction of viral replication. READ MORE

  7. 5. Studies of drug resistance in minor HIV quasispecies

    Author : Halime Ekici; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The main objective was to study drug resistance mutations (DRM) in the HIV-1 reverse transcriptase (RT) gene of minor HIV-1 quasispecies, not detectable with standard techniques. Sensitive allele-specific PCR (AS- PCR) and next-generation sequencing (NGS) were developed to study resistance to drugs of relevance in low- and middle-income countries (LMIC); the nucleoside analogue RT inhibitor (NRTI) lamivudine (3TC) and the non-nucleoside RT inhibitors (NNRTIs) efavirenz (EFV) and nevirapine (NVP).
