Surprising immune system cells discovery

Immune system cells are connected to each other by an extensive network of tiny tunnels that, like a building's hidden pneumatic tube system, are used to shoot signals to distant cells.

Study clarifies insulin's role in blocking release of energy in patients with type II diabetes

Chronically high levels of insulin, as is found in many people with obesity and Type II diabetes, may block specific hormones that trigger energy release into the body, according to researchers at the University of California, San Diego (UCSD) School of Medicine.

Prions rapidly 'remodel' good protein into bad

Two Brown Medical School biologists have figured out the fate of healthy protein when it comes in contact with the infectious prion form in yeast: The protein converts to the prion form, rendering it infectious. In an instant, good protein goes bad.

Carbon nanotubes as transport agents for antimycotics (antifungal agents)

Putting pharmaceutical agents into the body isn't hard, but getting them into targeted areas can be problematic. If drugs aren't taken up by a large enough proportion of cells, a suitable "transport agent" must be used.

Screening test for cells that activate immune system

UT Southwestern Medical Center researchers are the first to create a large-scale, cell-based screening method that identifies which compounds activate immune-response cells that hold promise for future cancer-fighting vaccines.

Simple new way to modify collagen, paving the way for better infection-fighting bandages

Collagen often pops up in beauty products and supermodel lips. But by mating collagen with a molecular hitchhiker, materials scientists at Johns Hopkins hope to create some important medical advances.

New way to "image" the internal chemistry of bacteria

As part of the search for better ways to track and clean up soil contaminants, scientists at the U.S. Department of Energy's Brookhaven National Laboratory and Stony Brook University have developed a new way to "image" the internal chemistry of bacteria.

Immunity - another important function of the mitochondria

Researchers have discovered a surprise lurking inside mitochondria, the power plants that are present in every cell. It turns out that these powerhouses also contain a protein that triggers the immune system to attack viral invaders.

Scientists have developed a new dye that could offer noninvasive early diagnosis of Alzheimer's disease

MIT scientists have developed a new dye that could offer noninvasive early diagnosis of Alzheimer's disease, a discovery that could aid in monitoring the progression of the disease and in studying the efficacy of new treatments to stop it.

Analytical tool to help detect cancer

Scientists have long used ultra-fine glass tubes known as capillaries to analyze the chemical makeup of substances. Called capillary electrophoresis, or CE, the method applies high voltage to the capillaries, and by measuring the rate that the various materials move through the capillaries, researchers are able to identify individual compounds.

Immune system more concerned with damage detected than foreign invaders, such as viruses

A well-respected researcher who is now a chief of an immunology laboratory of the National Institutes of Health (NIH) has rocked the boat in the past few years for the experts in the understanding of the autoimmune system.

New gene technique useful for identifying genes and drug targets for diseases such as cancers and diabetes

A collaborative project between American and Chinese researchers developed a way to study the function of genes in mice and man by using a moveable genetic element from moths, according to a report in the journal Cell.

Body's own defense mechanism causes some of the most serious asthma symptoms

McGill University Health Centre (MUHC) scientists have discovered that our body's own defense mechanism causes some of the most serious asthma symptoms.

Fluorescence spectroscopy able to detect the presence of inflammatory cells that are associated with critical atherosclerotic plaques

Because atherosclerotic plaque typically builds up without symptoms and leads to more than 1 million deaths in America each year, the search is on to develop early detection devices that will enable physicians to offer treatment before the disease progresses to advanced stages.

Early detection of Alzheimer's coming soon?

Alzheimer's disease is the most common form of old-age dementia and has become the fourth most common cause of death in the USA. The cause of the disease is protein deposits, called amyloid plaques, in the brain.

Bone marrow-derived cells fail to meet high expectations says Bonn study

Adult stem cells taken from bone marrow are the "shooting stars" of their field. Many research scientists have been speculating that the cells might be able to pass through the blood into diseased organs and replace defective tissue. Such cells are seen as the potential key to the treatment of certain muscle diseases.

Customized gene chip offers clues to prognosis in cases of neuroblastoma

Rather than covering the entire genome, the microarray focuses on suspect regions of chromosomes for signs of deleted genetic material known to play a role in the cancer.
