Naturally Occurring Co-infection of Avian Leukosis Virus (subgroups A-E) and Reticuloendotheliosis Virus in Green Peafowls (Pavo muticus)

Brazilian Journal of Poultry Science
Most of the neoplastic diseases affecting poultry have a viral etiology, such as Marek’s disease, avian leukosis/sarcoma and reticuloendotheliosis. In the present paper, histopathology and molecular methods were performed, in addition of necropsy and ...

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.

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

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.

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 ...

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.

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 ...

Rodent models of tumours of the central nervous system

Molecular Oncology, Volume 18, Issue 12, Page 2842-2870, December 2024.
We describe the evolution of experimental systems, illustrated here in a timeline to show changing popularity over time. Starting with chemical and viral carcinogenesis, systems then developed into increasingly sophisticated genetically modified animal models.

Detection of ALV p27 in cloacal swabs and virus isolation medium by sELISA

BMC Veterinary Research, 2019
Background Avian leukosis (AL), which is caused by avian leukosis virus (ALV), has led to substantial economic losses in the poultry industry. The kit used to detect all ALV-positive chickens in breeder flocks is very important for efficiently ...

Establishment of an avian leukosis virus subgroup A-resistant cell line

Journal of Integrative Agriculture, 2017
Rapid diagnostic methods for classifying avian leukosis subgroups in the field were needed for routine, large-scale screening. As a first step in method development, we inserted the avian leukosis virus subgroup A (ALV-A) env gene into plasmid pcDNA3.1 ...
