Dr. Stephen Barr, a researcher in the Department of Medical Microbiology & Immunology at the U of A, says his team identified a human gene called TRIM22 that can block HIV infection in a cell culture by preventing the assembly of the virus.
Barr says “interestingly, when we prevent cells from turning on TRIM22, the normal interferon response (a natural defense produced by our cells to fight infection by viruses such as HIV) is useless at blocking HIV infection. This means TRIM22 is an essential part of our body’s ability to fight off HIV.”
Barr’s team finds the results very exciting because it shows our bodies have a gene that is capable of stopping the spread of HIV. They are now trying to figure out why this gene does not work in people infected with HIV and if there is a way to turn this gene on in those individuals.
“We hope that our research will lead to the design of new drugs and/or vaccines that can halt the person-to-person transmission of HIV and the spread of the virus in the body, thereby blocking the onset of AIDS.”

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
