Herpes Virus

Understanding of herpesvirus infection advanced by new research
www.sciencedaily.com

Herpes simplex virus (HSV) infections last a lifetime. Once a person has been infected, the virus can remain dormant (latent) for years before periodically reactivating to cause recurrent disease. This poorly understood cycle has frustrated scientists for years. Now, scientists have identified a set of protein complexes that are recruited to viral genes and stimulate […]

Using herpes drugs to slow down Alzheimer's disease could become reality
www.sciencedaily.com

The first clinical study to investigate if herpes virus drugs can have an effect on fundamental Alzheimer’s disease processes has been launched. The research group has previously demonstrated a correlation between herpes virus infection and an increased risk of Alzheimer’s disease.

Herpes, not quite so species specific after all
www.sciencedaily.com

A new study challenges the tenet of herpes viruses being strictly host-specific. Scientists have discovered that gammaherpesviruses switch their hosts more frequently than previously thought. In fact, bats and primates appear to be responsible for the transfer of these viruses to other mammals in many cases.

Research provides clues to how Zika virus breaches the placental barrier
www.sciencedaily.com

New research reveals that in pregnant women, Zika virus infection damages certain cells that affect placental formation and function. Furthermore, herpes simplex virus-2 (HSV-2) infection augments placental sensitivity to Zika virus by enhancing the expression of receptors that allow Zika virus to enter cells.

New mouse model of Zika sexual transmission shows spread to fetal brain
www.sciencedaily.com

The Zika virus, commonly transmitted through a bite from an infected mosquito, is also capable of leaping from person to person through sexual transmission. However, the mechanisms Zika uses to invade the body from the genitals, and the havoc it may wreak from there, are unclear. To better understand the process, a group of researchers […]

Researchers find herpes strain in the nervous system
www.sciencedaily.com

There are a couple strains of herpes so common that researchers estimate 90% of the human population have them. These strains, human herpes 6 and human herpes 7, usually do not cause severe symptoms when people acquire them. But researchers know that under certain circumstances, dormant herpes viruses in the body can unexpectedly come roaring […]
