Virus cures mice of human brain cancer
A cancer-fighting virus has eliminated malignant brain tumors and prolonged survival in mice with a single injection. Reporting in the journal Cancer Research, Canadian scientists from Calgary and...
View ArticleStudy suggests way to re-energize immune response to chronic viral infection
Like boxers wearied by a 15-round bout, the immune system’s CD8 T cells eventually become “exhausted” in their battle against persistent viral infection, and less effective in fighting the disease. In...
View ArticleScientists Visualize Protein Interaction That May Initiate Viral Infection
Biologists at Purdue University have taken a “snapshot” of a Velcro-like protein on a cell’s surface just after it attached to the dengue virus, a linkup thought to initiate the early stages of...
View ArticleMice Lacking Key Immune Component Still Control Chronic Viral Infections
Despite lack of a key component of the immune system, a line of genetically engineered mice can control chronic herpes virus infections, researchers at Washington University School of Medicine in St....
View ArticleResearch produces images of HIV that may shape vaccine
As the world marks the 25th year since the first diagnosed case of AIDS, groundbreaking research by scientists at Florida State University has produced remarkable three-dimensional images of the virus...
View ArticleBattery electrodes self-assembled by viruses
Genetically modified viruses that assemble into electrodes could one day revolutionise battery manufacturing. Researchers in the US have created viruses that automatically coat themselves in metals and...
View ArticleHIV-1′s high virulence might be an accident of evolution
The virulence characteristic of HIV-1–the virus predominantly responsible for human AIDS–might amount to an accident of evolution, new evidence reveals. A gene function lost during the course of viral...
View ArticleCracking a virus protection shield
Scientists reveal the structure of a protein that packages the viral genome and helps viruses to replicate while avoiding human immune reactions Ebola, measles and rabies are serious threats to public...
View ArticleReconstructed 1918 influenza virus induces immune response that fails to protect
An analysis of mice infected with the reconstructed 1918 influenza virus has revealed that although the infection triggered a very strong immune system response, the response failed to protect the...
View ArticleNew study indicates moderate exercise may protect against colds
A moderate exercise program may reduce the incidence of colds. A study published in the November issue of The American Journal of Medicine, led by researchers at Fred Hutchinson Cancer Research Center,...
View ArticleHow to Resurrect an Extinct Retrovirus
French researchers have resurrected a retrovirus that became trapped in the human genome about five million years ago. Pieced together from existing sequences in human DNA, the reconstructed virus was...
View ArticleFighting HIV by Building a New Killer Frankenstein Virus
In order to find out how one of the world’s most devastating diseases overcomes state-of-the-art drugs, scientists led by Dr. Vineet KewalRamani at National Cancer Institute (NCI) are biohacking and...
View ArticleResearchers use laser, nanotechnology to rapidly detect viruses
Waiting a day or more to get lab results back from the doctor’s office soon could become a thing of a past. Using nanotechnology, a team of University of Georgia researchers has developed a diagnostic...
View ArticleBuildup of damaged DNA in cells drives aging
The accumulation of genetic damage in our cells is a major contributor to how we age, according to a study being published today in the journal Nature by an international group of researchers. The...
View ArticleStudy uncovers a lethal secret of 1918 influenza virus
In a study of non-human primates infected with the influenza virus that killed 50 million people in 1918, an international team of scientists has found a critical clue to how the virus killed so...
View ArticleFast and ultrasensitive optical virus sensor
Scientists of the Biophysical Engineering Group of the University of Twente in The Netherlands have developed an ultrasensitive sensor that can be used in a handheld device to, within minutes, detect...
View Article3D Animation of HIV Replication
This is an outstanding 3D animation of HIV replication cycle. I especially loved the entry part, which is like watching a science fiction movie. The animation is fairly accurate representation of what...
View ArticleScientists find bird flu antibody
Scientists working in Switzerland, Vietnam and the United States say they have isolated antibodies that they hope could offer protection against several different strains of the virus simultaneously....
View ArticleVirus Uses Tiny RNA To Evade The Immune System
In the latest version of the hide-and-seek game between pathogens and the hosts they infect, researchers have found that a virus appears to cloak itself with a recently discovered gene silencing device...
View ArticleAncient retrovirus sheds light on HIV pandemic
Human resistance to a retrovirus that infected chimpanzees and other nonhuman primates 4 million years ago ironically may be at least partially responsible for the susceptibility of humans to HIV...
