Finding opens new pathways for treating or preventing autoimmune diseases

A rare genetic defect that can trigger a host of diseases from type 1 diabetes to alopecia has helped explain the imbalance of immune regulator and killer cells in autoimmune disease.

The ratio of phosphatidylcholine to phosphatidylethanolamine influences membrane integrity and steatohepatitis

An imbalance in the lipid content of the liver appears to trigger the downward spiral that leads some with fatty liver disease to advance to full-blown liver failure, according to a new study in the May Cell Metabolism.

Study reveals structure of E. coli multidrug transporter protein

This new study could potentially help researchers find new ways to avoid the problem of multidrug resistance and enhance the potency of existing drug compounds.

A pericellular collagenase directs the 3-D development of white adipose tissue

In the journal Cell, researchers report the serendipitous discovery that the initial development of fat requires a "remodeling" protein that must first make way for the lipid-laden tissue's growth.

Allergy-free soybeans

Researchers have isolated two Chinese soybean lines that grow without the primary protein linked to soy allergies in children and adults.

New approaches to genetic disease, based on cells' own ability to correct themselves

New approaches to genetic disease, based on cells' own ability to correct themselves, will be outlined today at the annual conference of the European Society of Human Genetics in Amsterdam, The Netherlands.

Bacterial binding in the stomach

Scientists have determined that decay-accelerating factor (DAF), a protein found in epithelial cells in the stomach, acts as a receptor for the bacteria Helicobacter pylori. Blocking this interaction could lead to new drugs that reduce the risk of peptic ulcer disease or gastric cancer.

Inflammation markers identify fatigue in breast cancer survivors

Researchers at the University of California, Los Angeles have defined conditions associated with disabling fatigue that persists for years in almost a third of breast cancer survivors, according to a study in the May 1 issue of Clinical Cancer Research.

An engineered virus that tracks down and compels cancer cells to eat themselves

An engineered virus tracks down and infects the most common and deadly form of brain cancer and then kills tumor cells by forcing them to devour themselves, researchers at The University of Texas M. D. Anderson Cancer Center report.

Scientists discover a master key to microbes' pathogenic lifestyles

For some microbes, the transformation from a benign lifestyle in the soil to that of a potentially deadly human pathogen is just a breath away.

Potentially powerful tool for designing novel Alzheimer's treatments

Researchers have identified a protein that reins in the rogue activity of the molecules that make the amyloid-beta protein--which may prevent normal brain function in people with Alzheimer's disease. Their findings reveal a potentially powerful tool for designing novel Alzheimer's treatments.

New method found showing how nerve cells can selectively filter and transfer signals

Scientists from Gvttingen and Bochum find evidence for a new mechanism, with which our nerve cells are able to filter signals and transfer them selectively.

Study indicates how drug efficacy can be increased by manipulating the signalling mechanism

Researchers believe they have found a way to change the action of 60 percent of currently available medications, in some cases making them many times more effective, according to an article published in the April 21 edition of the journal Science. The discovery has the potential to improve treatments for diseases including heart disease, cancer, diabetes, depression and arthritis. The study describes a new way to manipulate perhaps the most important signaling mechanism in human cells: G-protein coupled receptors (GPCRs).

Researchers figure out how nuclear pores duplicate before cells divide

Researchers have long wondered how nuclear pores - the all-important channels that control the flow of information in and out of a cell's nucleus - double in number to prepare for the split to come when a cell divides. Now, for the first time, scientists at the Salk Institute for Biological Studies watched as new funnel-like pore structures formed from scratch, and inserted themselves into the nuclear membrane.

Protein made by cancer virus explains how the virus spreads

New research shows that a protein made by a cancer virus causes infected immune cells to cling to other immune cells, enabling the virus to spread.

New technique to speed discovery of drug targets in chemical genetics

Researchers at Fox Chase Cancer Center have developed a new technique to speed discovery of drug targets in chemical genetics. Fox Chase researcher Jeffrey R. Peterson, Ph.D., and his colleagues describe a new way to swiftly find the proteins targeted by small molecule inhibitors during high-throughput screening (HTS) experiments. The new work offers a critical solution to a common stumbling block in this booming field of drug discovery.

Prefrontal cortex in the brain damaged by both alcoholism and chronic smoking

Alcoholism is commonly associated with chronic smoking, and both alcohol and nicotine are believed to act on the same brain region. Research builds upon previous research that identified four potential alcohol-sensitive genes in the prefrontal cortex, finding that smoking also influences the expression of these genes.

New method allows heart beat triggers to be viewed and better understood

Researchers have developed unique chemical dyes that have made it possible to see what the naked eye has never seen before: action potentials, or voltage changes, of cardiac cells - including those deep inside the heart, which trigger and determine the pace of heartbeats.

Research into toxins points to development of better medicines

Researchers have combined magnetic resonance spectroscopy with special protein synthesis procedures to uncover how potassium channels and toxins combine and change in structure. This work could make it possible to develop medications for high blood pressure and many other diseases connected to potassium channel failure .

New methods for revealing nerve-muscle activity in live animals

Picking up a pencil, running a marathon, even the simple act of breathing - every time we move a muscle we depend on a series of finely-tuned interactions at the junction of nerve fiber and muscle cell.
