A Novel Multi-Epitope Vaccine For Cross Protection Against Hepatitis C Virus (HCV): An Immunoinformatics Approach

Background: Hepatitis C virus (HCV) causes acute and chronic human hepatitis infections. Due to the high genetic diversity and high rates of mutations in the genetic material so far there is no approved vaccine against HCV. Materials and Methods: The aim of this study was to determination B and T cell conserved epitopes of E1 and E2 proteins from HCV and construction of a chimeric pepti...

Conformational epitope on gp120 important in CD4 binding and human immunodeficiency virus type 1 neutralization identified by a human monoclonal antibody.

A human monoclonal antibody designated 15e is reactive with the envelope glycoprotein (gp120) of multiple isolates of human immunodeficiency virus type 1 (HIV-1). Antibody 15e also neutralizes HIV-1 with broad specificity and blocks gp120 binding to CD4. Characterization of the 15e epitope shows that it is conformation dependent and is distinct from previously recognized functional domains of g...

Epitope-enhanced conserved HIV-1 peptide protects HLA-A2-transgenic mice against virus expressing HIV-1 antigen.

HIV epitopes may have developed to be poor immunogens. As a counterapproach HIV vaccine strategy, we used epitope enhancement of a conserved HIV reverse transcriptase (RT) epitope for induction of antiviral protection in HLA-A2-transgenic mice mediated by human HLA-A2-restricted CTLs. We designed two epitope-enhanced peptides based on affinity for HLA-A2, one substituted in anchor residues (RT-...

Immunoinformatics Design of a Multi-epitope-based Vaccine Against Colorectal Cancer

Background: Bioinformatic approaches for designing vaccines have become a promising alternative to conventional methods. We herein designed a multi-epitope-based vaccine against colorectal cancer (CRC). Methods: Used peptides in the CRC vaccines were retrieved from databases of PubMed, Web of Science, Google Scholar, and Clinical trials. The adjuvants of Mycobacterial heparin-binding hemagglut...
