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.

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.

Virus or Avian Myeloblastic Leukosis

Poultry Science, 1956
Abstract INTRODUCTION AVIAN leukosis is a complex of diseases which are not only of much economic importance, but which, in addition, comprise one category of virus-induced tumors. As a consequence, knowledge of the diseases is of fundamental interest in its bearing on the problem of cancer as a whole. Since the initial reports of the viral etiology

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.

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.
