Background and purpose: Influenza virus is one of the most important respiratory infectious agents. Viral antigenic variations are major problems for vaccine production process. At present, many researches have focused on conserved domains of influenza virus antigenic peptides for subunit vaccine development. Hemagglutinin small subunit (HA2) and the 23 amino acid extracellular N-terminal domai...

Background and Objective: Shiga toxin (STx) is the main virulence factor in Shigella Dysenteriae type I and is composed of an enzymatic subunit STxA monomer and a receptor-binding STxB homopentamer. Shigella toxin B subunit (STxB) is a non-toxic homopentameric protein responsible for toxin binding and internalization into target cells by interacting with glycolipid (Gb3). Cholera toxi...
