Comparative Magnitude of Cross-Strain Conservation of HIV Variable Loop Neutralization Epitopes
Although the sequence variable loops of the human immunodeficiency virus' (HIV-1) surface envelope glycoprotein (gp120) can exhibit good immunogenicity, characterizing conserved (invariant) cross-strain neutralization epitopes within these loops has proven difficult. We recently developed a method to derive sensitive and specific signature motifs for the three-dimensional (3D) shapes of the HIV...
متن کاملProximal glycans outside of the epitopes regulate the presentation of HIV-1 envelope gp120 helper epitopes.
Glycosylation of HIV-1 envelope gp120 determines not only the proper structure, but also the immune responses against this Ag. Although glycans may be part of specific epitopes or shield other epitopes from T cells and Abs, this study provides evidence for a different immunomodulatory function of glycans associated with gp120 residues N230 and N448. These glycans are required for efficient MHC ...
متن کاملepitopes immediately below the base of the V3 loop of gp120 as targets for the initial autologous neutralizing antibody response in two HIV-1 subtype B-infected individuals.
Epitopes that drive the initial autologous neutralizing antibody response in HIV-1-infected individuals could provide insights for vaccine design. Although highly strain specific, these epitopes are immunogenic, vulnerable to antibody attack on infectious virus, and could be involved in the ontogeny of broadly neutralizing antibody responses. To delineate such epitopes, we used site-directed mu...
متن کاملHigh efficient production of Pr55(gag) virus-like particles expressing multiple HIV-1 epitopes, including a gp120 protein derived from an Ugandan HIV-1 isolate of subtype A.
The main goal of this study was to investigate a novel approach for an efficient and reproducible production of Virus-Like Particles (VLPs) expressing multiple HIV-1 epitopes. The HIV-1 Pr55(gag)-based VLPs have been produced in a Baculovirus expression system, using a transfer vector able to support the independent expression of different open reading frames (ORFs). In this regard, the gp120 d...
متن کاملMapping cross-clade HIV-1 vaccine epitopes using a bioinformatics approach.
UNLABELLED The genomic variability of HIV viruses circulating in different regions of the world has impeded the development of a globally relevant HIV vaccine. Broadly conserved HIV-1 cytotoxic T cell (CTL) epitopes were identified by screening protein sequences in the Los Alamos National Laboratory (LANL) HIV sequence database with a sequence parsing and matching algorithm (Conservatrix). Puta...
