Researchers have discovered an immune system 'kill switch' that destroys blood stem cells when the body is under severe stress, such as that induced by chemotherapy and systemic infections. The discovery could have implications for protecting the blood system during chemotherapy or in diseases associated with overwhelming infection, such as sepsis. The kill switch is triggered when internal immune cell signals that protect the body from infection go haywire. Dr Seth Masters, Dr Motti...

Silent Watchmen Attack To Defend The Nervous System
2012-10-16 17:20:26

In many pathologies of the nervous system, there is a common event - cells called microglia are activated from surveillant watchmen into fighters. Microglia are the immune cells of the nervous system, ingesting and destroying pathogens and damaged nerve cells. Until now little was known about the molecular mechanisms of microglia activation despite this being a critical process in the body. Now new research from the Montreal Neurological Institute and Hospital — The Neuro - at McGill...

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
2012-07-09 17:16:37

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...
