WebMay 7, 2024 · The FMDV antigenic site A (AgSA) includes the key virus recognition motif (an RGD amino acid triad) for its major host cellular receptor (αVβ6 integrin). AgSA is located on capsid protein 1 (VP1) and triggers the main humoral neutralizing response ( 4 ). WebSome monoclonal antibodies (mAB) also provide antigenic sites that cause antigenic variation. The antigenic sites are sequenced by mAB neutralization resistant mutants [7] .
