Marek's disease virus phosphoprotein pp38 (commonly used as the canonical antigen name; other specific MDV antigens include Meq oncoprotein and major capsid glycoproteins) (pp38, Meq)

Marek's disease virus antigens are a group of viral proteins expressed by Gallid alphaherpesvirus 2 (Marek's disease virus, MDV), including immunodominant phosphoproteins (such as pp38), oncoproteins (Meq), and viral glycoproteins (such as glycoprotein C). These antigens are critical for pathogenesis, immune response, and serve as key targets for vaccine development, serological diagnosis, and molecular monitoring of infection and virulence in poultry. They are not classical therapeutic targets but are essential biomarkers and immunological targets for disease control and poultry health management. In summary, "Marek's disease virus antigen" is too vague and covers multiple MDV proteins with distinct roles; for structured data, use the specific antigen’s name (e.g., "Marek’s disease virus phosphoprotein pp38" or "Marek’s disease virus Meq oncoprotein").

Vaccine-induced immune response: live-attenuated or recombinant vaccines contain or express MDV antigens to induce protective immunity in chickens; Serological detection: antibodies bind antigens for lab diagnosis
