Envelope glycoprotein GP120: Envelope glycoprotein GP120 (or gp120) is a glycoprotein exposed on the surface of the HIV envelope. The 120 in its name comes from its molecular weight of 120 kDa.Vpx: Vpx is a virion-associated protein encoded by human immunodeficiency virus type 2 HIV-2 and most simian immunodeficiency virus (SIV) strains, but that is absent from HIV-1. It is similar in structure to the protein Vpr that is carried by SIV and HIV-2 as well as HIV-1.KeliximabPseudotyping: Pseudotyping is the process of producing viruses or viral vectors in combination with foreign viral envelope proteins. The result is a pseudotyped virus particle.CXC chemokine receptors: CXC chemokine receptors are integral membrane proteins that specifically bind and respond to cytokines of the CXC chemokine family. They represent one subfamily of chemokine receptors, a large family of G protein-linked receptors that are known as seven transmembrane (7-TM) proteins, since they span the cell membrane seven times.Coles PhillipsProtein primary structure: The primary structure of a peptide or protein is the linear sequence of its amino acid structural units, and partly comprises its overall biomolecular structure. By convention, the primary structure of a protein is reported starting from the amino-terminal (N) end to the carboxyl-terminal (C) end.HIV Vaccine Trials Network: The HIV Vaccine Trials Network (HVTN) is a non-profit organization which connects physicians and scientists with activists and community educators for the purpose of conducting clinical trials seeking a safe and effective HIV vaccine. Collaboratively, research professionals and laypeople review potential vaccines for safety, immune response, and efficacy.Cryptic self epitopes: In immunology, cryptic self epitopes are a source of autoimmunity.Management of HIV/AIDS: The management of HIV/AIDS normally includes the use of multiple antiretroviral drugs in an attempt to control HIV infection. There are several classes of antiretroviral agents that act on different stages of the HIV life-cycle.KASH domains: KASH domains are conserved C-terminal protein regions less than ~30 amino acids. KASH is an acronym for Klarsicht, ANC-1, Syne Homology.Co-option (biology)Plaque reduction neutralization test: The Plaque reduction neutralization test is used to quantify the titre of neutralising antibody for a virus.CCR5 receptor antagonist: CCR5 receptor antagonists are a class of small molecules that antagonize the CCR5 receptor. The C-C motif chemokine receptor CCR5 is involved in the process by which HIV, the virus that causes AIDS, enters cells.Lipid bilayer fusion: In membrane biology, fusion is the process by which two initially distinct lipid bilayers merge their hydrophobic cores, resulting in one interconnected structure. If this fusion proceeds completely through both leaflets of both bilayers, an aqueous bridge is formed and the internal contents of the two structures can mix.HIV-positive people: HIV-positive people are people who have the human immunodeficiency virus HIV, the agent of the currently incurable disease AIDS.Glycosylation: Glycosylation (see also chemical glycosylation) is the reaction in which a carbohydrate, i.e.Cell–cell fusogens: Cell–cell fusogens are glycoproteins that facilitate the fusion of cell to cell membranes. Cell-cell fusion is critical for the merging of gamete genomes and development of organs in multicelluar organisms.Monoclonal antibody therapyProximity ligation assay: Proximity ligation assay (in situ PLA) is a technology that extends the capabilities of traditional immunoassays to include direct detection of proteins, protein interactions and modifications with high specificity and sensitivity. Protein targets can be readily detected and localized with single molecule resolution and objectively quantified in unmodified cells and tissues.Database of protein conformational diversity: The Database of protein conformational diversity (PCDB) is a database of diversity of protein tertiary structures within protein domains as determined by X-ray crystallography. Proteins are inherently flexible and this database collects information on this subject for use in molecular research.Reaction coordinateSEA Native Peptide LigationAdult-onset immunodeficiency syndrome: Adult-onset immunodeficiency syndrome is a provisional name for a newly diagnosed immunodeficiency illness. The name is proposed in the first public study to identify the syndrome.Symmetry element: A symmetry element is a point of reference about which symmetry operations can take place. In particular, symmetry elements can be centers of inversion, axes of rotation and mirror planes.
