L-VAC in mice identifies multiple capsule-permeable protein antigens from Streptococcus pneumoniae that trigger rapid hepatic clearance of blood-borne bacteria and enable broad cross-serotype protection.
- Why it matters: Bacterial capsules shield antigens, limiting immune clearance and making noncapsular vaccine discovery difficult, especially for invasive, multidrug-resistant encapsulated pathogens.
- What they did: The Liver-based Vaccine Antigen Capture (L-VAC) platform combines antibody-mediated screening with in vivo visualization of hepatic bacterial clearance in mice, then tests immunization with the identified proteins, including multivalent formulations.
- The result: Only proteins localized at or near the capsular surface are targetable for liver sinusoid capture, and immunization—particularly multivalent—confers broad cross-serotype protection.
