Interfering with cell recruitment reduces damaging inflammation in animals´ models of several disorders Massachusetts General Hospital (MGH) researchers — along with collaborators from Massachusetts Institute of Technology (MIT) and Alnylam Pharmaceuticals — have found a way to block, in an animal model, the damaging inflammation that contributes to many disease conditions. In their report receiving early online publication in Nature Biotechnology, the investigators...

Scientists reveal how a type of white blood cells, called Natural Killer cells, protect the body from tumors and virus-infected cells Scientists reveal in more detail than ever before how white blood cells kill diseased tissue using deadly granules, in research published today in PLoS Biology. The researchers, from Imperial College London and the University of Oxford, used 'optical' laser tweezers and a super-resolution microscope to see the inner workings of white blood cells at the...

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...


Word of the Day
omphalos
  • The navel or umbilicus.
  • In Greek archaeology: A central boss, as on a shield, a bowl, etc.
