Self-assembling peptide nanoparticles as vaccines against infection with norovirus

摘要

Self-assembling peptide nanoparticles (SAPN) incorporating T-cell epitopes and displaying the P domain of the norovirus protein VP1 are described. The nanoparticles of the invention consist of aggregates of a continuous peptide chain comprising two coiled coil oligomerization domains connected by a linker segment wherein one or both oligomerization domains incorporate T-cell epitopes within their peptide sequence. These nanoparticles are useful as vaccines and adjuvants for the prevention and treatment of norovirus infections.
