Marmosets infected with HHV-6A/B intranasally were initially asymptomatic but later developed significantly accelerated disease and died in a shorter period of time. HHV-6 proteins were found at high levels in the brain lesions.
Investigators at Washington University have sequenced a murine herpesvirus and determined that it is closely related to HHV-6 & 7. Named Murine Rosesolovirus (MRV), the virus causes severe depletion of CD4+ T cells and thymic necrosis in young mice. The authors believe that MRV will be a useful mouse model to study the impact of HHV-6 & 7 in humans.
Virologists led by Serge Barcy, PhD at the Seattle Children’s Research Institute and University of Washington have identified a homolog for HHV-7 in pigtail macaques They were surprised to learn that it could be detected in the peripheral nerve ganglia, and hope to use their new animal model to explore how HHV-7 might play a role in demyelinating diseases.
Seattle group announces the discovery of novel HHV-6 and HHV-7 homologs in pig-tailed macaques
New model of HHV-6A infection demonstrates persistent abortive infection and neuroinflammation via TLR9
Branka Horvat, MD, PhD, Director of Research at the International Centre for Infectiology Research in Lyon, France (INSERM), and her doctoral student Josephine Reynaud have recently published an important paper on a new transgenic mouse model
Could treatment of HHV-6A co-infections slow AIDS progression?
Dr. Steven Jacobson’s laboratory at the US National Institute of Health has developed a novel marmoset model for the study of HHV-6 infection.
