PFOS mediates immunomodulation in an avian cell line that can be mitigated via a virus infection

BMC Veterinary Research, 2019
Background Per- and polyfluoroalkyl substances (PFASs) are environmentally persistent and bioaccumulative chemicals. Immunomodulation is among the most concerning of toxic effects linked with PFAS exposure in mammalian models. However, no studies had yet

Marek’s Disease Virus Cluster 3 miRNAs Restrict Virus’ Early Cytolytic Replication and Pathogenesis

Viruses, 2020
Herpesvirus-encoded microRNAs (miRNAs) have been discovered in infected cells; however, lack of a suitable animal model has hampered functional analyses of viral miRNAs in vivo.

A Tiny RNA that Packs a Big Punch: The Critical Role of a Viral miR-155 Ortholog in Lymphomagenesis in Marek’s Disease

Frontiers in Microbiology, 2017
MicroRNAs (miRNAs) are small non-coding RNAs that have been identified in animals, plants, and viruses. These small RNAs play important roles in post-transcriptional regulation of various cellular processes, including development, differentiation, and ...

Common occurrence ofGallid herpesvirus-2with reticuloendotheliosis virus in chickens caused by possible contamination of vaccine stocks [PDF]

Journal of Applied Microbiology, 2015
The aim of this study was to investigate the common occurrence of reticuloendotheliosis virus (REV) among Gallid herpesvirus 2 (GaHV-2) infected chickens. The possible cause of this co-occurrence may be linked to contaminated vaccine stocks, which were also examined.The study was conducted on 25 field isolates of GaHV-2 collected between 2007 and 2013 ...

In vivo expression patterns of microRNAs of Gallid herpesvirus 2 (GaHV-2) during the virus life cycle and development of Marek’s disease lymphomas [PDF]

Virus Genes, 2015
In the past decade, a large number of microRNAs (miRNAs) have been identified in the viral genome of Gallid herpesvirus 2 (GaHV-2), which is historically known as Marek's disease virus type 1. The biological role of most GaHV-2 miRNAs remains unclear. In the present study, we have performed an overall gene expression profile of GaHV-2 miRNAs during the

An Overview on Marek’s Disease Virus Evolution and Evidence for Increased Virulence in Brazil

Brazilian Journal of Poultry Science, 2019
Marek’s disease virus (MDV) has been shown to be evolving to higher virulence. One of the genetic sites involved in virulence which enables such characterization is the 339-amino acid Meq protein encoding gene (meq).

Role of DNA Methylation and CpG Sites in the Viral Telomerase RNA Promoter during Gallid Herpesvirus 2 Pathogenesis

Journal of Virology, 2020
Previous studies demonstrated that telomerase RNAs possess functions that promote tumor development independent of the telomerase complex. vTR is a herpesvirus-encoded telomerase RNA subunit that plays a crucial role in virus-induced tumorigenesis and is expressed by a robust viral promoter that is highly regulated by the c-Myc oncoprotein binding to ...

Air sampling for detection of infectious laryngotracheitis (ILT) in commercial poultry flocks

BMC Research Notes, 2020
Objective Infectious laryngotracheitis (ILT) is an acute and highly contagious viral respiratory disease of poultry, caused by gallid herpesvirus 1 (ILTV), which causes significant economic losses. Due to recent outbreaks of ILT in Australia, it has been
