Differentiated Presynaptic Input to OLMɑ2 Cells Along the Hippocampal Dorsoventral Axis: Implications for Hippocampal Microcircuit Function

Hippocampus, Volume 35, Issue 5, September 2025.
ABSTRACT The dorsal and ventral hippocampus have distinct processing properties, but it remains unclear if interneuron subtypes differ in connectivity along the dorsoventral axis. Oriens lacunosum‐moleculare (OLM) interneurons, identified by the Chrna2 gene, are known to regulate memory processes differently along this axis. OLMɑ2 cells bidirectionally

A PRELIMINARY REPORT OF SUBGROUP J AVIAN LEUKOSIS VIRUS-INFECTION IN IMPORTED BROILER PARENT CHICKENS [PDF]

Veterinary Medical Journal - Giza, 1999
Three imported broiler parent farms suffering from high incidence of tumor mortality were investigated. Gross pathological lesions were suggestive of the novel subgroup J of avian leukosis virus (ALV) infection.

Risk of Mortality From Esophageal Cancer Among US Poultry Workers, 1950−2019

American Journal of Industrial Medicine, Volume 68, Issue 8, Page 711-723, August 2025.
ABSTRACT Background While research suggests poultry industry workers have an increased risk of cancer mortality, little is known about their risk of esophageal cancer mortality. We investigated the association between working with poultry and esophageal cancer mortality while concurrently investigating other occupational and nonoccupational risk ...

Advances on ALV-J in China over the past two decades

Journal of Integrative Agriculture
Avian leukosis is an important tumorigenic disease caused by the avian leukosis virus (ALV) in poultry. ALVs belong to the retroviral family and are classified into 11 subgroups (ALV-A to ALV-K). Among them, ALV-J was first introduced into China in 1999,

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

Marek\u27s Disease - Leukosis [PDF]

, 1969
During the past few years there have been many significant new findings concerning the avian leukosis complex. Until recently these diseases were termed visceral leukosis, neural leukosis, or avian lymphomatosis.

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.

Histogenetic correlations between the reticular tissue and the different types of avian leukosis and related neoplasms

, 1965
Development of different types of avian leukosis bears a close histogenetic correlation to pre-existent reticular tissue, especially to the retothelial system.

Application of chicken microarrays for gene expression analysis in other avian species [PDF]

, 2009
With the threat of emerging infectious diseases such as avian influenza, whose natural hosts are thought to be a variety of wild water birds including duck, we are armed with very few genomic resources to investigate large scale immunological gene ...
