Dengue and other viruses may have developed tricks that let them reproduce inside macrophages

A monoclonal antibody that can effectively treat mice infected with West Nile virus has an intriguing secret: Contrary to scientists' expectations, it does not block the virus's ability to attach to host cells. Instead, the antibody somehow stops the infectious process at a later point.

Discovery may lead to development of more effective antibiotics

Researchers at the Georgia Institute of Technology and the John Innes Centre in the United Kingdom have uncovered a mechanism with which disease-causing bacteria may thwart the body's natural defense responses. The findings, which could ultimately lead to the development of more effective antibiotics, appear in the September 29, 2005 issue of the journal Nature.

New Stat1 and interferon findings

By altering a molecule called Stat1, which is involved in cellular immune signaling, scientists have succeeded in making the molecule more responsive and thus more efficient. This old protein with a new twist may eventually be used to improve the body's defense against infection.

Fruit fly discovery could lead to a completely new approach to tackling some cancers

Scientists studying the humble fruit fly have found a family of proteins that enhances the sensitivity of a cell to a hormone that can trigger abnormal growth and cancer. Their discovery could lead to a completely new approach to tackling some cancers and the development of new drugs to stop uncontrolled growth in a wide variety of tumour cells.

Emergence of "POZ Parties"

The emergence of "POZ Parties" - parties exclusively for HIV positive men to meet other HIV positive men for sex - signals the potential to spread HIV "superinfection,"suggests research in Sexually Transmitted Infections.

Common form of thalassaemia can be managed without blood transfusion

Haemoglobin E â thalassaemia - the commonest form of severe thalassaemia in many Asian countries - can be managed without transfusion in many patients, suggests a research letter published online today (Thursday September 29, 2005) by The Lancet.

Combination HRT appears to double the breast cancer risk in women who smoke

Older women who have smoked for 11 or more "pack years" - the lifetime equivalent of a pack a day for at least 11 years - face a 30 percent to 40 percent increased risk of developing breast cancer as compared to women who've never smoked, according to new findings from researchers at Fred Hutchinson Cancer Research Center.

Simulator helps stroke patients learn to drive again

A high-fidelity simulator that allows people to practice driving on a computer-generated course can help stroke patients learn to drive again, researchers have found.

Possible therapy that could control blood pressure

A newly developed virus that introduces a blood pressure-lowering gene into cells and enables that gene to maintain blood pressure at healthy levels for four months promises to take gene therapy for the disorder a step closer to reality, said researchers at Baylor College of Medicine in a report released online in the Proceedings of the National Academy of Sciences.

Fndings could lead to a treatment for idiopathic interstitial pneumonia

An incurable, deadly lung disorder, "idiopathic interstitial pneumonia" (IIP), whose causes were mysterious arises from a combination of a genetic predisposition and damage due to inhaled chemicals, notably from cigarette smoking, Duke University Medical Center researchers have found.

Transplanted insulin-producing cells survive better when the activation of NKT cells are blocked

Scientists in Japan have found a way to improve on a promising diabetes treatment. In the October 3 issue of The Journal of Experimental Medicine, Masaru Taniguchi and colleagues report that transplanted insulin-producing cells survive better when the activation of a specific type of immune cell is blocked.
