Scientists Identify Antivirus System in Host Cells

Scientists have discovered a new anti-virus system

Viruses have led scientists at Washington University School of Medicine in St. Louis to the discovery of a security system in host cells. Viruses that cause disease in animals beat the security system millennia ago.

Colorized negative stained transmission electron micrograph (TEM) depicts a number of Marburg virus virions.

Over millions of years, retroviruses, which insert their genetic material into the host genome as part of their replication, have left behind bits of their genetic material in vertebrate genomes. In a recent study, published July 29 in the open-access journal PLoS Pathogens, a team of researchers have now found that human and other vertebrate genomes also contain many ancient sequences from Ebola/Marburgviruses and Bornaviruses — two deadly virus families.

Infected female Aedes aegypti mosquitoes transmit the virus causing dengue fever, but they are rendered flightless in a new strain genetically engineered by UCI and British scientists.

A new strain of mosquitoes in which females cannot fly may help curb the transmission of dengue fever, according to UC Irvine and British scientists.

‘Broad Spectrum’ Antiviral Fights Multitude of Viruses

100201113801-large

Ebola virus. A small-molecule “broad spectrum” antiviral may be able to fight a host of viruses by attacking them through some feature common to an entire class of viruses.

The development of antibiotics gave physicians seemingly miraculous weapons against infectious disease. Effective cures for terrible afflictions like pneumonia, syphilis and tuberculosis were suddenly at hand. Moreover, many of the drugs that made them possible were versatile enough to knock out a wide range of deadly bacterial threats.
