Venezuelan equine encephalitis virus antigen (VEEV antigen)

"Venezuelan equine encephalitis virus antigen" is a non-specific collective term for viral proteins of VEEV, an Alphavirus (family Togaviridae) that causes outbreaks of encephalitis in horses and humans[4]. The virus is composed of a single-stranded RNA genome (~11.5 kb) encoding nonstructural replication proteins and structural proteins, including the **envelope glycoproteins E1 and E2** (mediating cell entry and key antibody targets), and the **capsid protein**. These viral proteins act as antigens, eliciting host immune responses during infection or after vaccination, and are the basis of serological diagnostics and immunization strategies[1][4][5][6][7]. Research and immunotherapeutic or vaccine development specifically target individual proteins (e.g., E2 glycoprotein), not the general antigen designation.
