PCR Based Evidence of Reticuloendotheliosis Virus Infection in Chickens from Turkey [PDF]

Pakistan Veterinary Journal, 2011
In this study, presence of avian leukosis virus (ALV) and reticuloendotheliosis virus (REV) was investigated in neoplastic cases observed in breeder hens older than 20 weeks in commercial broiler breeders. Tumor samples were examined by PCR combined with

New developments in biotechnology applied to animals: An assessment of the adequacy and sufficiency of current EFSA guidance for animal risk assessment

EFSA Journal, Volume 23, Issue 8, August 2025.
Abstract EFSA was requested by the European Commission to provide a scientific opinion on new developments in biotechnology, including new genomic techniques, as applied to animals for food, feed and other agricultural uses. A horizon‐scanning exercise identified a variety of animals obtained with new genomic techniques, with the potential to reach the

Intravital Imaging of Immune Responses in the Cancer Microenvironment

Cancer Medicine, Volume 14, Issue 8, April 2025.
ABSTRACT Background To date, many types of immune cells have been identified, but their precise role in cancer immunity remains unclear. Understanding the immune responses involved in cancer and the cancer microenvironment is becoming increasingly important for elucidating disease mechanisms.

A novel subgroup of exogenous avian leukosis virus in chickens

Journal of General Virology, 1991
An avian leukosis virus with a wide host range belonging to a new subgroup for chickens was isolated from meat-type chicken lines. The virus, of which HPRS-103 strain is the prototype, was of low oncogenicity in chickens but appeared to behave like an exogenous leukosis virus.

The ageing virus hypothesis: Epigenetic ageing beyond the Tree of Life

BioEssays, Volume 47, Issue 1, January 2025.
Viruses would age when the epigenetic signals they need to carry out their life cycle are degraded. Given the abundance and age of viruses, epigenetic aging of viruses would extend theories on the evolution of aging beyond cellular organisms, and encourage new models of viral dynamics and new anti‐viral therapies.

Epidemiology of the highly pathogenic avian influenza H5N1 in Northern Vietnam: Applications for surveillance and control [PDF]

, 2011
The epidemiology and the sanitary situation of avian influenza changed dramatically with the emergence of the highly pathogenic H5N1 virus (HPAI) in 1996. As a consequence, knowledge previously accumulated on the epidemiology and the ecology of the avian

Prolactin: A Key Immunoregulator in Viral Infections and Autoimmune Diseases

International Journal of Endocrinology, Volume 2025, Issue 1, 2025.
Prolactin (PRL) is secreted by various cells in the anterior pituitary gland, mammary glands, placenta, uterus, ovaries, testes, skin, adipose tissue, endothelial cells, immune system, and central nervous system. The expression and secretion of PRL are influenced by several factors such as suckling, thyrotropin‐releasing hormone (TRH), cytokines ...

Integrative RNA-seq and ChIP-seq analysis unveils metabolic regulation as a conserved antiviral mechanism of chicken p53

Microbiology Spectrum
The tumor suppressor p53, primarily functioning as a transcription factor, has exhibited antiviral capabilities against various viruses in chickens, including infectious bursal disease virus (IBDV), avian leukosis virus subgroup J (ALV-J), and avian ...

Pathology and Molecular Diagnosis of Marek’s Disease Virus in Chickens in Nigeria

Scientifica, Volume 2025, Issue 1, 2025.
Marek’s disease caused by Marek’s disease virus (MDV) serotype 1 is an economically important neoplastic disease of poultry. Diagnosis of this disease is usually based on clinical signs, postmortem lesions, and diagnostic tests like cytology, histopathology, and molecular‐based methods.
