  1. 1. Immune recognition and early virus-cell interactions. Glycobiological aspects on HIV-1 gp120

    Författare :Gregers J. Gram; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Human immunodeficiency virus type 1 HIV-1 ; glycoprotein; gp120; glycosylation.;

    Sammanfattning : Human immunodeficiency virus types 1 and 2 (HIV-1 and HIV-2) are the etiological agents of AIDS in humans. The viral envelope glycoproteins gp120 and gp41 mediate the early virus-cell interaction of HIV with the target cells. LÄS MER

  3. 2. Studies towards ß-turn mimetics, synthesis of kedarosamine from threonine, and synthesis of glycopeptides from mucins and gp120

    Författare :Tatjana Vuljanic; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Tn antigen; glycopeptides; glycosylation; diastereselective reduction; kedarosamine; kedarcidin chromophore; amino acids; peptide T; ß-turn mimetic; Organisk kemi; gp120; Organic chemistry;

    Sammanfattning : The secondary structure of proteins is crucial for proper function of the protein in biological systems. Peptide T, an octapeptide from the envelope glycoprotein gp120 of the HIV virus, has previously been shown to be responsible for binding to the CD4 receptor on T helper/inducer lymphocytes. LÄS MER

  4. 3. Effects of galectins and antibodies in HIV infection; Novel Assays

    Författare :Enas Sheik-Khalil; Institutionen för laboratoriemedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; HIV-1; galectin-1; galectin-8; neutralizing antibodies; cell-cell fusion; Microscale anisotropy assay; virus binding assay; glycosylation; gp120; Automated plaque reduction assay; CellProfiler; NeutNet;

    Sammanfattning : The high variability of the HIV envelope glycoproteins (Env), and their heavy glycan coating, contributes to the limited host immune control. Still, broadly neutralizing antibodies (bnAbs) are found in some chronically infected HIV-infected individuals, which has spurred the research on antibody-based vaccines. LÄS MER

  5. 4. HIV-1 evolution, disease progression and molecular epidemiology of HIV-1 single and HIV-1 and HIV-2 dual-infected individuals in Guinea-Bissau

    Författare :Joakim Esbjörnsson; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; HIV-1; HIV-2; Guinea-Bissau; subtype; disease progression; evolution; coreceptor tropism; CXCR4; gp120; V1-V3; CD4%; CD8%; soluble immune markers;

    Sammanfattning : The two genetically related human lentiviruses known today, HIV-1 (which is pandemic) and HIV-2 (which mainly is confined to West Africa), are the causative agents of AIDS. Progressive immune dysfunction and AIDS develop in most cases of untreated HIV-1 infection, but only in approximately 25-30% of HIV-2 infected individuals. LÄS MER

  7. 5. HIV-1 envelope protein gp120. Glycovirology of the V3 loop

    Författare :Britt Losman; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; AIDS; HIV-1; Carbohydrates; V3-region; V1-region; Coreceptors;

    Sammanfattning : The human immunodeficiency virus type 1 (HIV-1) infection usually is lethal as a consequence of the acquired immunodeficiency syndrome (AIDS). HIV-1 is an enveloped virus and the trimeric envelope glycoprotein complex, gp120/gp41, is responsible for binding of the virus both to the primary cellular receptor CD4 and the coreceptors, CXCR4 and CCR5.
