Discovery of potential drug targets for sepsis

"We have identified a key connection of signaling pathways in the cascade of events leading to sepsis. This defines a crucial point where the immune system spirals out of control to cause severe sepsis and where there is an opportunity for therapeutic intervention," says Scripps Research Professor Wolfram Ruf, who led the research with his postdoctoral fellow Frank Niessen.

Scientists devise approach that stops HIV at earliest stage of infection

Their study, which appears this week in the online Early Edition of the Proceedings of the National Academy of Sciences (PNAS), may re-energize attempts to create a preventive/therapeutic vaccine against HIV, say the authors.

Inverted DNA turns quiet developmental gene into a potent driver of t-cell lymphoma

A gene crucial for embryonic development can quickly become a potent cancer promoter in adult mice after a genetic misalignment, according to researchers from Fox Chase Cancer Center, causing white blood cells to become cancerous spontaneously.

Cause of effectiveness discovered for a cirrhosis treatment useful in 40 percent of patients

Scientists of the Center for Applied Medical Research (CIMA) of the University of Navarra have discovered the molecular mechanism responsible for the effectiveness of an existing treatment for primary biliary cirrhosis, which combines two substances in order to produce an effect that does not result from either substance separately.

Hormones produced by the heart eliminate pancreatic cancer in mice

Hormones produced by the heart eliminated human pancreatic cancer in more than three-quarters of the mice treated with the hormones and eliminated human breast cancer in two-thirds of the mice, according to researcher David Vesely, a doctor at the James A. Haley Veterans Hospital in Tampa and a professor at the University of South Florida (USF).

Protein that stimulates blood vessel growth worsens ovarian cancer

A protein that stimulates blood vessel growth worsens ovarian cancer, but its production can be stifled by a tiny bit of RNA wrapped in a fatty nanoparticle, a research team led by scientists at The University of Texas M. D. Anderson Cancer Center reports in the Journal of the National Cancer Institute.

New Alzheimer's patent by Affiris

Affiris GmbH has secured another Europe-wide patent for an innovative method of treating Alzheimer's disease. This new blood-cleansing method is similar to dialysis and is designed to reduce the amount of harmful protein deposits in the brain. It is based on the AFFITOME technology established by Affiris, which was patented in October 2007 for an Alzheimer's vaccine.
