In healthy adults, polyclonal antibodies to RSV and human metapneumovirus preF consistently target the highly neutralization-sensitive preF apex (site O), with distinct site-by-site distributions between viruses.
- Why it matters: Neutralizing preF-directed immunity is known to matter, but how naturally circulating polyclonal antibodies map across preF antigenic sites for RSV versus hMPV was unclear.
- What they did: Serological profiling, site-specific antibody competition assays, and EMPEM were used to map preF antibody recognition in healthy adults, linking preF binding to virus neutralization and testing antigenic-site patterns.
- The result: All donors showed detectable preF-binding antibodies that positively correlated with neutralization and recognized multiple sites; EMPEM found apex targeting plus less abundant responses at sites II, III, IV, and V, and antibody-bound destabilized preF suggests transient preF opening.
