Use of Foot-and-Mouth Disease Virus Non-coding Synthetic RNAs as Vaccine Adjuvants.

Abstract

The ncRNAs are short RNA transcripts with sequence and structure resembling that of specific domains in the non-coding regions of the foot-and-mouth disease (FMD) virus (FMDV ) genome. These synthetic molecules induce a robust antiviral response and have been shown to enhance the immune response and protection induced by an FMD inactivated vaccine in pigs. Here, we describe the method for ncRNAs synthesis, formulation, and delivery into mice and pigs for studies focused on testing the adjuvant effect of RNA-based strategies in combination with veterinarian vaccines.
