With new tool, Children's Hospital of Philadelphia researchers show how immune system attacks infected cells Making use of a new "super resolution" microscope that provides sharp images at extremely small scales, scientists have achieved unprecedented views of the immune system in action. The new tool, a stimulated emission depletion (STED) microscope, shows how granules from natural killer cells pass through openings in dynamic cell structures to destroy their targets: tumor cells and...

Like humans, mice that live in their natural habitat encounter bacteria and other pathogens that exercise their immune system, yet the lab mice typically used in immunology studies are raised in isolation from most diseases. A study on natural killer cells in wild mice published this week in Molecular Ecology examines the hypothesis that the unsterile living conditions faced by humans and wild mice may improve the readiness of the immune system to fight new infections. The findings suggest...

The Findings Open the Door to the Development of Novel Drugs for Early-Stage Tumors Scientists at The Scripps Research Institute have shown that a particular white blood cell plays a direct role in the development and spread of cancerous tumors. Their work sheds new light on the development of the disease and points toward novel strategies for treating early-stage cancers. The study was published in September 2011 print issue of the American Journal of Pathology. Scripps Research...

The same trait that makes a rare immune cell invaluable in fighting some infections also can be exploited by other diseases to cause harm, two new studies show. In papers published online in Immunity, scientists at Washington University School of Medicine in St. Louis reveal that the cells, known as CD8 alpha+ dendritic cells (CD8a+ DCs), can help the body beat back infection by a common parasite, but the same cells can be hijacked by a bacterium to decimate the body´s defenses....

SANTA ROSA, Calif., Aug. 16, 2011 /PRNewswire/ -- Groundbreaking research demonstrates the ability of a specific form of Modified Citrus Pectin (MCP) to greatly enhance immune function. The study found that MCP activated B-cells in a dose-dependent manner, and induced a highly significant dose-dependent activation of T-cytotoxic cells and Natural Killer (NK) cells. The NK-cell's cancer killing activity was demonstrated against live leukemia cancer cells. The study is published in the...

Feeding mannan oligosaccharides (MOS) can fine-tune the immune system of pigs, suggests a new University of Illinois study. "When it comes to keeping pigs healthy, there are some potentially powerful tools we can use in the diet besides antibiotics," said James Pettigrew, U of I professor of animal science. "We have a tendency to think that we can administer health through a needle, by giving pigs antibiotics, and even through systems like all-in/all-out pig flow. These are important, but...

A study from scientists at Queen Mary, University of London, sheds new light on why people who experience serious trauma or go through major surgery, can suffer organ damage in parts of the body which are seemingly unconnected to the injury. The study, published today in Nature Immunology*, examines the way certain white blood cells, called neutrophils move out of blood vessels to defend damaged organs against injury or infection. This is normally a one-way journey but researchers were...

Researchers at the Stanford University School of Medicine have taken a machine already in use for the measurement of impurities in semiconductors and used it to analyze immune cells in far more detail than has been possible before. The new technology lets scientists take simultaneous measurements of dozens of features located on and in cells, whereas the existing technology typically begins to encounter technical limitations at about a half-dozen. The investigators were able not only to...

Cedars-Sinai research offers model Scientists at Cedars-Sinai Medical Center have discovered how a molecular receptor on the surface of white blood cells identifies when invading fungi have established direct contact with the cell surface and pose an infectious threat. The receptor called Dectin-1, studied in the laboratory of David Underhill, PhD, an associate professor in Cedars-Sinai's Inflammatory Bowel and Immunobiology Research Institute, detects fungi and instructs white blood cells...


Word of the Day
callithump
  • A somewhat riotous parade, accompanied with the blowing of tin horns, and other discordant noises; also, a burlesque serenade; a charivari.
'Callithump' is a back-formation of 'callithumpian,' a 'fanciful formation' according to the Oxford English Dictionary. However, the English Dialect Dictionary, says 'Gallithumpians' is a Dorset and Devon word from the 1790s that refers to 'a society of radical social reformers' or 'noisy disturbers of elections and meetings.'
