New Insights on Virus Replication Targets The Infection Linked to Birth Defects

Insights on virus replication from the University of Edinburgh could help to target infections that are linked to birth defects.

The new insights on virus replication could help to pave way for therapies that could stop its spread.

A research team from the University of Edinburgh has discovered a key molecule that has been linked to Human Cytomegalovirus (HCMV) infection.

New Insights Detail Immature Zika Virus Structure
New details related to the immature zika virus structure were revealed to develop effective antiviral treatments and vaccines.

‘New insights on virus study could help to target infections that are linked to birth defects.’

HCMV infections could be harmless for healthy people but could cause miscarriage and birth defects during pregnancy.

Tests on infected cells found that blocking the molecule with a chemical inhibitor stops the virus from multiplying.

The molecule - called VCP - is a component of the infected cell rather than a substance produced by the virus itself.

New Insights into Ebola Virus
Genetic mutation acquired by the Ebola virus during the 2013-16 helped the virus better target human cells, reveal The Scripps Research Institute (TSRI) scientists.

Researchers at the University of Edinburgh's Roslin Institute found the virus is dependent on VCP to replicate its genetic material and multiply.

Chemicals that block the activity of VCP are 10 times more powerful at stopping the virus than existing medications that target HCMV directly, the study found.

Interferon Drug Promises Hope for Ebola Virus Treatment
Ebola virus causes fatal illness, interferon drug may show promise for treatment, reveals study.

By targeting the affected cells instead of the virus, the approach could also cut the chances of the virus becoming resistant to the therapy, researchers say.

Drugs that target VCP are already being developed as potential therapies for cancer. Studies to check whether the drugs are safe for use will be needed before they could be tested as a therapy for the virus.

Insights into the Structural Clues of the Human Immunodeficiency Virus
The very first native blueprint in the context of HIV for studying the mechanisms of integrase strand transfer inhibitors is now available.

HCMV is extremely common. It infects at least 30 per cent of the population in the developed world and up to 100 per cent of people in developing countries.

It can be life-threatening for people with a weakened immune system, such as transplant recipients and people infected with HIV.

Infection during pregnancy can lead to hearing loss and intellectual disabilities in unborn babies.

The study is published in the journal PLOS Pathogens.

Dr Finn Grey, a Senior Research Fellow at the University of Edinburgh's Roslin Institute, said: "Human Cytomegalovirus infection is an important human disease. By gaining a better understanding of how the virus works, we can develop improved antiviral drugs. While more work is required, this study shows the potential of such approaches."
