Protease-mediated maturation of M-PMV reverse transcriptase into a functional heterodimer. [PDF]

Protein Sci
Abstract Reverse transcriptase (RT) of retroviruses orchestrates viral replication, yet its structural diversity remains poorly understood. Well‐studied RTs, such as those from HIV‐1, murine leukemia virus, and avian myeloblastosis virus, were characterized decades ago, but less prominent retroviruses have escaped detailed analysis.

Investigating Infectious Organisms of Public Health Concern Associated with Wild Meat

Transboundary and Emerging Diseases, Volume 2023, Issue 1, 2023., 2023
The wild meat trade poses a significant threat to public health as it facilitates the spillover of zoonotic pathogens through high‐risk activities such as the hunting, butchering, trade, and consumption of wild animals. Despite the health risks and association with marking epidemics including SARS, Ebola, and COVID‐19, the global wild meat trade ...

Diagnostic accuracy of Abbott Architect Assay as a screening tool for human T‐cell leukaemia virus type‐1 and type‐2 infection in a London teaching hospital with a large solid organ transplant centre

Transfusion Medicine, Volume 32, Issue 3, Page 256-260, June 2022., 2022
Abstract Aim In the United Kingdom, organ donors/recipients are screened for evidence of human T‐cell leukaemia virus type‐1 and type‐2 (HTLV‐1/2) infections. Since the United Kingdom is a low prevalence country for HTLV infections, a screening assay with high sensitivity and specificity is required.

The antiviral and immunomodulatory activities of propolis: An update and future perspectives for respiratory diseases

Medicinal Research Reviews, Volume 42, Issue 2, Page 897-945, March 2022., 2022
Abstract Propolis is a complex natural product that possesses antioxidant, anti‐inflammatory, immunomodulatory, antibacterial, and antiviral properties mainly attributed to the high content in flavonoids, phenolic acids, and their derivatives. The chemical composition of propolis is multifarious, as it depends on the botanical sources from which ...

A pooled testing system to rapidly identify cattle carrying the elite controller BoLA‐DRB3*009:02 haplotype against bovine leukemia virus infection

HLA, Volume 99, Issue 1, Page 12-24, January 2022., 2022
As genetically resistant individuals, the “elite controllers” (ECs) of human immunodeficiency virus infection have been focused on as the keys to developing further functional treatments in medicine. In the livestock production field, identifying the ECs of bovine leukemia virus (BLV) infection in cattle is desired to stop BLV transmission chains on ...

First Evidence of Bovine Leukemia Virus in Culicoides Biting Midges and the Stable Fly Stomoxys calcitrans Collected on Cattle Farms in Poland. [PDF]

Transbound Emerg Dis
Bovine leukemia virus (BLV) is a cell‐associated retrovirus of cattle transmitted mainly through the transfer of infected lymphocytes, but the possible role of hematophagous insects in its epidemiology remains incompletely understood. This study investigated BLV DNA in field‐collected Culicoides biting midges and Stomoxys calcitrans from cattle farms ...
