Marek’s Disease Virus Infection of Natural Killer Cells
Microorganisms, 2019 Natural killer (NK) cells are key players in the innate immune response. They kill virus-infected cells and are crucial for the induction of adaptive immune responses. Marek's disease virus (MDV) is a highly contagious alphaherpesvirus that causes deadly

The Emergence of a vv + MDV Can Break through the Protections Provided by the Current Vaccines
Viruses, 2020 Marek’s disease (MD) is an infectious malignant T-cell lymphoma proliferative disease caused by Marek’s disease virus (MDV). In recent years, the emergence of very virulent (vv) and/or very virulent plus (vv +) strains of MDV in the field has been ...

BioMed Research International, Volume 2011, Issue 1, 2011., 2011 Bacterial artificial chromosome (BAC) vectors containing the full‐length genomes of several herpesviruses have been used widely as tools to enable functional studies of viral genes. Marek′s disease viruses (MDVs) are highly oncogenic alphaherpesviruses that induce rapid‐onset T‐cell lymphomas in chickens. Oncogenic strains of MDV reconstituted from BAC

Protection provided by Rispens CVI988 vaccine against Marek's disease virus isolates of different pathotypes and early prediction of vaccine take and MD outcome [PDF]
Avian Pathology, 2016 We tested the level of protection provided by the Rispens CVI988 (Rispens) vaccine against challenge with a virulent Marek's disease virus (MDV) pathotype (vMDV) and a very virulent pathotype (vvMDV) and the accuracy of a range of predictive measures of Marek's disease (MD) incidence and vaccine take.
