    摘要： The present disclosure provides modified human herpesvirus glycoprotein B (gB) proteins that incorporate unique mechanisms for generating proteins that mimic their native conformation to enhance their immunogenicity. The modified herpesvirus gB proteins insert a peptide linker at the furin cleavage site in the extracellular domain of herpesvirus gB. When expressed, the gB subunit associates in triplicate to produce a homotrimeric complex, mimicking the native conformation of the gB protein. Also provided are protein complexes comprising a homotrimeric complex of a modified herpesvirus gB protein and herpesvirus gH and gL proteins. Also provided are nucleic acids encoding the modified herpesvirus gB proteins, methods of inducing or suppressing an immune response in a subject by administering a vaccine comprising the modified herpesvirus gB protein, or nucleic acid encoding the same, or a protein complex comprising a homotrimeric complex of the modified herpesvirus gB protein and herpesvirus gH and gL proteins.
