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 ). WebAug 11, 2024 · To develop more effective vaccines or peptide vaccines, numerous FMDV studies have been undertaken to identify these neutralizing antigenic sites in more detail . Neutralizing antigenic sites have been identified for serotype A ( 15 – 17 ), O ( 18 – 21 ), C ( 22 ), Asia-1 ( 23 ), and SAT2 ( 19 , 24 , 25 ).
WebAug 9, 2024 · FMDV is classified into seven distinct serotypes, i.e., O, A, C, Asia 1, Southern African Territories (SAT) 1, SAT 2 and SAT 3 [ 1 ]. FMDV infection is endemic in large areas of Africa, Asia, the Middle East, and South America. Seven geographical FMDV pools have been described in endemic areas that share similar viruses. WebJun 22, 2016 · Foot-and-mouth disease virus (FMDV) represses host translation machinery, blocks protein secretion, and cleaves cellular proteins associated with signal transduction and the innate immune response to infection. Non-structural proteins (NSPs) and non-coding elements (NCEs) of FMDV play a critical role in these biological processes. The …
WebAntigenic variants of foot-and-mouth disease virus (FMDV) were generated and frequently became dominant in clonal populations of FMDV (clone C-S8c1) grown in the absence of anti-FMDV antibodies. We have now passaged eight samples of the same FMDV clone in the presence of a limited amount of neutralizing polyclonal antibodies directed to the ... Webantigenic and immunogenic sites have been identified in several FMDV serotypes; for instance, the C-terminal stretch of VP1 (which, together with the GH loop, defines the main antigenic site 1 in serotype O), or sites involving different loops from the three accessible viral proteins (e.g. sites 2, 3 and 4 of FMDV O)28,56-59.
