It's a tragedy of war that innocent bystanders often get caught in the crossfire. But now scientists at the University of Pennsylvania and the University of Oxford have shown how a battle for survival at a microscopic level could leave humans as the unlikely victims. In work funded by the US Public Health Service and the Wellcome Trust, the researchers have found a possible explanation for why some bacteria turn nasty, even at great risk to their own survival. The body is home to a wide range...

Scientists are learning how our immune system senses and tracks down infection in the body by responding to chemical "scents" emitted by bacteria. Studying how immune cells manipulate their movement in response to external signals could shed light not only on how our immune system functions but also how cancer cells spread through the body and even how the brain wires itself. Speaking at the Society for General Microbiology's spring meeting in Edinburgh, Dr Holger Kress describes a new...

Findings show that ancient 'enemies within' can mimic sepsis Inflammation is at the root of most serious complications occurring after both infection and injury. But while the molecular course of events that leads from microbial infections to the inflammatory condition called sepsis is fairly well understood, it is far less clear how and why physical injury can result in a similarly dangerous inflammatory response. Now a study led by investigators at Beth Israel Deaconess Medical Center...

Scientists have long pondered the seeming contradiction that taking broad-spectrum antibiotics over a long period of time can lead to severe secondary bacterial infections. Now researchers from the University of Pennsylvania School of Medicine may have figured out why. The investigators show that "good" bacteria in the gut keep the immune system primed to more effectively fight infection from invading pathogenic bacteria. Altering the intricate dynamic between resident and foreign bacteria...

A team led by Yale University scientists has developed a new approach to studying how immune cells chase down bacteria in our bodies. Their findings are described in the November 15 issue of Nature Methods Advanced Online Publication. When bacteria enter our bodies they secrete molecules, leaving behind chemical trails as they move through our system. It has been known for some time that immune cells follow these trails in order to hunt the bacteria. However, studying exactly how immune cells...

University of Illinois at Chicago College of Medicine researchers have identified the important role a protein plays in the body's first line of defense in directing immune cells called neutrophils toward the site of infection or injury. Their results are described online in the Proceedings of the National Academy of Sciences. Neutrophils are white blood cells that are activated by chemical cues to move quickly to the site of injury or infection, where they ingest bacteria. When alerted to...

LAS VEGAS, Oct. 21 /PRNewswire/ -- Using live blood cell analysis, a resveratrol-based nutriceutical (Longevinex®) has been shown to visibly activate sluggish white blood cells in 9 of 10 human subjects within 30 minutes of consumption.

RESEARCH TRIANGLE PARK, N.C. and MIAMI, Oct. 13 /PRNewswire-FirstCall/ -- The Alpha-1 Foundation announced today that it has awarded two research grants to study how genetic variations in the alpha-1 antitrypsin (AAT) gene contribute to lung and liver damage in people with AAT deficiency. The inherited condition causes emphysema and liver disease. The research will also investigate whether AAT infusion therapy -- known as augmentation therapy -- minimizes liver damage among individuals...

Research led by Dr. Jay Kolls, Professor and Chairman of Genetics at LSU Health Sciences Center New Orleans, has identified a therapeutic target for acute lung injury resulting in acute respiratory distress syndrome, a highly fatal complication of influenza infection. The research, which will be published in The Journal of Immunology in October, is currently available in the Next in the JI section online at http://0-www.jimmunol.org.innopac.lsuhsc.edu/cgi/reprint/jimmunol.0900995v1....

Scientists at the Burnham Institute for Medical Research in California say they've discovered reactive oxygen plays a key role in cancer metastasis. The researchers, led by Professor Sara Courtneidge, said they determined reactive species, such as superoxide and hydrogen peroxide, help form invadopodia -- cellular protrusions implicated in cancer cell migration. They found inhibiting reactive oxygen reduces invadopodia formation, thereby limiting cancer cell invasion. Reactive oxygen has a...
