HHV-6 in the news!

In Latest Scientific News by Kristin Loomis

After years of very little interest by the scientific community, there has suddenly been a lot of interest in HHV-6A, which along with HHV-7, appears to be central to the progression of Alzheimer’s disease.

Low dose emetine shows promise as a herpesvirus antiviral

In All, Latest Scientific News, Treatments - Antiviral by Kristin Loomis

Investigators at Johns Hopkins have determined that emetine, an older drug used to treat dysentery as well as to induce vomiting, is also effective against cytomegalovirus (CMV/HHV-5). Not only was emetine effective at an extremely low dose, it demonstrated a synergistic effect when combined with ganciclovir in a mouse model of CMV infection and it worked at a much earlier stage of viral replication than the drugs currently in use.

HHV-6A gene activity linked to central nervous system disease

In All, CNS Disease, Latest Scientific News by Kristin Loomis

Chinese investigators from Nanjing Medical University report that HHV-6A infection of astrocytes are associated with differences in gene expression that are also found in several CNS diseases including Alzheimer’s, glioma and multiple sclerosis. The investigators used gene ontology analysis to determine the biological processes, cellular components, and molecular functions of the differentially expressed genes and signalling pathways.

EBV and HHV-6B but no CMV found in astrocytomas by digital droplet PCR

In All, Cancer, CNS Disease, Latest Scientific News by Kristin Loomis

A group from the National Institute of Neurological Disorders and Stroke, NIH, has reported finding Epstein-Barr Virus (EBV) and HHV-6 but no cytomegalovirus (CMV) in astrocytomas, a brain tumor comprising approximately one quarter of all gliomas diagnosed. The group used digital droplet PCR (ddPCR), a technique that is highly precise but less sensitive than nested PCR and immunohistochemistry, techniques that have been used in previous studies.
