Conserved presence of G-quadruplex forming sequences in the Long Terminal Repeat Promoter of Lentiviruses [PDF]

open access: yes, 2017
G-quadruplexes (G4s) are secondary structures of nucleic acids that epigenetically regulate cellular processes. In the human immunodeficiency lentivirus 1 (HIV-1), dynamic G4s are located in the unique viral LTR promoter.

Retroviral Infections in Sheep and Goats: Small Ruminant Lentiviruses and Host Interaction

open access: yesViruses, 2013
Small ruminant lentiviruses (SRLV) are members of the Retrovirus family comprising the closely related Visna/Maedi Virus (VMV) and the Caprine Arthritis-Encephalitis Virus (CAEV), which infect sheep and goats. Both infect cells of the monocyte/macrophage

Purification of Escherichia coli-expressed HIS-tagged Maedi-Visna p25 core antigen by Ni2+-chelate affinity chromatography

open access: yesVeterinární Medicína, 2001
In this study, recombinant histidine tagged p25 capsid protein of Maedi-Visna virus was developed. Part of the viral genome coding p25 protein was positioned downstream and in frame with a metal binding domain in pRSET-B vector.

Evolution of specific antibodies and proviral DNA in milk of small ruminants infected by small ruminant lentivirus [PDF]

open access: yes, 2013
The diagnosis of Small Ruminant Lentivirus (SRLV) is based on clinical signs, pathological lesions and laboratory testing. No standard reference test for the diagnosis of maedi visna has been validated up to the present, and it is puzzling that tests ...

Investigation of the Seroprevalence of Lentivirus ovivismae and Lentivirus capartenc (Formerly Known as Maedi‐Visna and Caprine Arthritis‐Encephalitis Virus) Infections in Sheep and Goats in the Yozgat Region

open access: yesVeterinary Medicine and Science, Volume 12, Issue 3, May 2026.
This study conducted in the Yozgat region determined a prevalence of 6.35% for maedi‐visna in sheep and 17.5% for caprine arthritis encephalitis in goats, providing critical data for small ruminant health and disease management in the area. ABSTRACT Background Lentivirus ovivismae and Lentivirus capartenc (formerly maedi‐visna and caprine arthritis ...
