Integrative expression system for delivery of antibody fragments by lactobacilli

Appl Environ Microbiol. 2011 Mar;77(6):2174-9. doi: 10.1128/AEM.02690-10. Epub 2011 Jan 21.

Abstract

A series of expression cassettes which mediate secretion or surface display of antibody fragments was stably integrated in the chromosome of Lactobacillus paracasei. L. paracasei producing surface-anchored variable domain of llama heavy chain (VHH) (ARP1) directed against rotavirus showed efficient binding to rotavirus and protection in the mouse model of rotavirus infection.
