Scripps Nanoparticle Vaccines Elicit Cross-Filovirus Antibodies in Mice

Pre-fusion locking plus glycan edits expose conserved sites for broader protection.

Overview

  • A Nature Communications Article-in-Press published on Dec. 12 details vaccine candidates that display redesigned filovirus glycoproteins on self-assembling protein nanoparticles.
  • Biochemical and structural analyses confirmed correct nanoparticle assembly and accurate antigen presentation.
  • In mouse studies, the candidates generated strong, cross-reactive neutralizing antibodies against several filoviruses.
  • Targeted modification of surface glycans exposed conserved epitopes that are typically hidden by the mucin and glycan shield.
  • The team plans to extend the structure-guided nanoparticle approach to Lassa and Nipah viruses, with support from the NIH and Scripps spin-off Uvax Bio.
