AI Summary
This article explores how the structure of VP2, a major outer capsid protein in the Bluetongue Virus (BTV), affects its antigenicity. Specifically, it compares the VP2 structure between the less virulent BTV1 serotype and the highly virulent BTV8 serotype. Understanding how the VP2 structure influences antigenicity can provide valuable insights into the development of vaccines and antiviral strategies for controlling BTV infections.
