Researchers synthesize compound to flush HIV out of hiding
Any hunter will tell you that when your quarry goes into hiding, you have to flush it out to get a good shot at it. Such is the case with HIV, the virus that causes AIDS.

The most natural drug
In an advance online publication in Nature, the researchers describe a method that can identify and clone human antibodies specifically tailored to fight infections. The new technology holds the potential to quickly and effectively create new treatments for influenza and a variety of other communicable diseases.

A step forward in virology
The vaccinia virus has a problem: it is a giant among viruses and needs a special strategy in order to infiltrate a cell and reproduce. Professor Ari Helenius and Postdoc Jason Mercer from ETH Zurich’s Institute for Biochemistry have now discovered what this strategy is. In the process, they stumbled upon new and surprising findings.

Discovery to hasten new malaria treatments, vaccines for children
April 25 is World Malaria Day 2008 and despite the grim statistics out of Africa there’s cause for celebration. Florida State University biologists have discovered an autoimmune-like response in blood drawn from malaria-infected African children that helps to explain why existing DNA-based anti-malaria vaccines have repeatedly failed to protect them.

Study finds T-cell multiplication unexpectedly delayed after infection
In a surprising outcome that overturns the conventional wisdom on the body’s immune response to infection, scientists at The Scripps Research Institute have shown that T cells do not begin proliferation until up to three days after infection.

Researchers discover how HIV turns food-poisoning into lethal infection
Nearly half of all HIV-positive African adults who become infected with Salmonella die from what otherwise would be a seven-day bout of diarrhea. Now, UC Davis School of Medicine scientists have discovered how salmonella becomes lethal for AIDS patients. Their findings also implicate a mechanism by which HIV evades the powerful drugs used to treat AIDS.

Scientists shine new light on inflammatory diseases
nvestigators at Hospital for Special Surgery have identified a new mechanism involved in the pathogenesis of inflammatory diseases such as rheumatoid arthritis. The mechanism may also shed some light on why gene therapy experiments that use adenoviruses to deliver genes to humans have run into problems. The study will appear online on March 16 in the journal Nature Immunology.
