Scientists' discovery of an important step in the body's process for healing wounds may lead to a new way of treating inflammation. A study published today in Current Biology details how an international team of researchers led by Monash University's Australian Regenerative Medicine Institute (ARMI) discovered the mechanism, which shuts down the signal triggering the body's initial inflammatory response to injury. When the body suffers a wound or abrasion, white blood cells, or...

Amyotrophic lateral sclerosis (ALS) is a progressive disease wherein the cells of the central nervous system (CNS) involved in movement and coordination are destroyed. Although the mechanism of ALS is not completely understood, inflammation is believed to play a role in the disease process. A recent study by Howard Weiner and colleagues at Harvard Medical School and Tufts School of Medicine investigated the role of inflammation in a mouse model of ALS. Weiner and colleagues found that the...

Researchers in Newcastle and Singapore have identified a new type of white blood cell which activates a killing immune response to an external source — providing a new potential target for vaccines for conditions such as cancer or Hepatitis B. Publishing in the journal Immunity, the team of researchers from Newcastle University in collaboration with A*STAR's Singapore Immunology Network (SIgN) describe a new human tissue dendritic cell with cross-presenting function. Dendritic...

Immune Cell DNA Used In Diagnostic Technique

By looking at signature chemical differences in the DNA of various immune cells called leukocytes, scientists have developed a way to determine their relative abundance in blood samples. The relative abundance turns out to correlate with specific cancers and other diseases, making the technique, described in two recent papers, potentially valuable not only for research but also for diagnostics and treatment monitoring. When a person is sick, there is a tell-tale sign in their blood: a...

Scientists at the University of East Anglia (UEA) have discovered a 'constant cloud' of potent inflammatory molecules surrounding the cells responsible for diseases such as thickening of the arteries and rheumatoid arthritis. Published online today by The Journal of Cell Science, the findings could eventually lead to new treatments for chronic inflammatory diseases. Cardiovascular disease arising from atherosclerosis (thickening of the arteries) kills around 17 million people worldwide...

Novel mechanism plays major role in inflammation Like detectives seeking footprints and other clues on a television "whodunit," science can also benefit from analyzing the tracks of important players in the body's molecular landscape. Klaus Ley, M.D., a scientist at the La Jolla Institute for Allergy & Immunology, has done just that and illuminated a key step in the journey of inflammation-producing immune cells. The finding provides powerful, previously unknown information about...

A new study helps to resolve an ongoing controversy about whether Langerhans cells (LCs) in human skin function to suppress the immune response and promote tolerance to normal human skin and its "friendly" microbial flora or mobilize a lethal attack against harmful foreign invaders. The research, published online May 3rd in the journal Immunity by Cell Press, reveals that, depending on the situation, these versatile immune cells can perform either function. Adult human skin contains...

Macrophages play a key role in the immune response, protecting organisms against infection and regulating the development of inflammation in tissue. Macrophages differ depending on where they are located and which tasks they perform. A scientist at TUM has been investigating whether these different types of cells have the same origin — and has come up with some surprising results. His findings reveal that there are two distinct macrophage cell lines that continue into adult life and...

Margination, the natural phenomenon where bacteria and leukocytes (white blood cells) move toward the sides of blood vessels, is the inspiration for a novel method for treating sepsis, a systemic and often dangerous inflammatory response to microbial infection in the blood. A team of researchers at the Massachusetts Institute of Technology and the National University of Singapore has designed a branchlike system of microfluidic channels, 20 micrometers (20 millionths of a meter, or about...
