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 ...

Avian Adenoviruses Infections with Special Attention to Inclusion Body Hepatitis/ Hydropericardium Syndrome and Egg Drop Syndrome [PDF]

, 2011
The first avian adenovirus (AAV) associated with clinical disease was isolated from an outbreak of respiratory disease in quail in 1950 (Olson, 1950). Since that time, AAVs have been found in all types and breeds of chickens and from a variety of other ...

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.

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 ...

Keratin 6a marks mammary bipotential progenitor cells that can give rise to a unique tumor model resembling human normal-like breast cancer. [PDF]

, 2011
Progenitor cells are considered an important cell of origin of human malignancies. However, there has not been any single gene that can define mammary bipotential progenitor cells, and as such it has not been possible to use genetic methods to introduce ...

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.
