Remnants of an Ancient Deltaretrovirus in the Genomes of Horseshoe Bats (Rhinolophidae) [PDF]

Viruses, 2018
Endogenous retrovirus (ERV) sequences provide a rich source of information about the long-term interactions between retroviruses and their hosts. However, most ERVs are derived from a subset of retrovirus groups, while ERVs derived from certain other ...

A dose-effect relationship for deltaretrovirus-dependent leukemogenesis in sheep [PDF]

Retrovirology, 2009
Background Retrovirus-induced tumors develop in a broad range of frequencies and after extremely variable periods of time, from only a few days to several decades, depending mainly on virus type.

Capture in the metabolic arena: co-selection of gamma and deltaretrovirus envelope glycoproteins and their receptors [PDF]

Retrovirology, 2009
Although all infectious and replication-competent retroviruses harbor an env gene, the origin of env remains unknown except for that of a few invertebrate retroviruses. It is generally admitted that infectious retroviruses have evolved from endogenous viral retrotransposons by insertion of an ''external'' gene that encodes for a fusion glycoprotein ...

North American Big Brown Bats (Eptesicus fuscus) Harbor an Exogenous Deltaretrovirus

mSphere, 2020
Bats are the reservoir for a large number of zoonotic viruses, including members of Coronaviridae (severe acute respiratory syndrome coronavirus [SARS-CoV] and SARS-CoV-2), Paramyxoviridae (Hendra and Nipah viruses), Rhabdoviridae (rabies virus), and ...

Detection of Bovine Leukemia Virus in Argentine, Bolivian, Paraguayan and Cuban Native Cattle Using a Quantitative Real-Time PCR Assay-BLV-CoCoMo-qPCR-2 [PDF]

Pathogens
Bovine leukemia virus (BLV), an oncogenic retrovirus of the genus Deltaretrovirus, causes enzootic bovine leukosis (EBL), the most prevalent neoplastic disease in cattle and a major source of economic loss.

Unique Structure and Distinctive Properties of the Ancient and Ubiquitous Gamma-Type Envelope Glycoprotein

Viruses, 2023
After the onset of the AIDS pandemic, HIV-1 (genus Lentivirus) became the predominant model for studying retrovirus Env glycoproteins and their role in entry.

Discovery of an endogenous Deltaretrovirus in the genome of long-fingered bats (Chiroptera: Miniopteridae) [PDF]

Proceedings of the National Academy of Sciences of the United States of America, 2017
Significance Retroviruses copy their RNA genome into complementary DNA, which is then inserted into the host chromosomal DNA as an obligatory part of their life cycle. Such integrated viral sequences, called proviruses, are passed to the infected cell progeny on cellular division.

Stage-Dependent Transcriptional Reprogramming of B-Cell Receptor Signaling and Antigen Presentation During Bovine Leukemia Virus-Driven Lymphomagenesis. [PDF]

Anim Genet
ABSTRACT Bovine leukemia virus (BLV), an oncogenic deltaretrovirus, establishes lifelong infection in cattle and induces enzootic bovine leukosis in a subset of animals following prolonged latency. Despite extensive evidence of immune dysregulation, stage‐specific transcriptional reprogramming of B cells, the primary viral reservoir remains ...

Comparison of the Prevalence of Bovine Leukemia Virus (BLV) in Holstein and Angus Cattle Breeds From Shandong Province, China. [PDF]

Microbiol Immunol
ABSTRACT Bovine leukemia virus (BLV) is widespread globally and causes economic losses in the cattle industry. Shandong Province plays a significant role in China's livestock industry, with an increasing importance in food of Holstein and Angus cattle. However, BLV prevalence in Holstein and Angus breeds in Shandong Province remains unclear.

Impact of BoLA-DRB3 Polymorphisms on Clonality of Bovine Leukaemia Virus-Infected Cells of Cattle With Lymphoma. [PDF]

HLA
ABSTRACT Bovine leukaemia virus (BLV) infects cattle, integrates into the host genome as a provirus, and induces a persistent infection that remains asymptomatic but can cause leukaemia/lymphoma. Most BLV‐infected cell clones are created by massive depletion, and a few of these infected cell clones expand through the mitotic cycle, leading to the onset
