Johns Hopkins Medicine Process suggests a new type of immunotherapy A team of researchers has devised a Pac-Man-style power pellet that gets normally mild-mannered cells to gobble up their undesirable neighbors. The development may point the way to therapies that enlist patients' own cells to better fend off infection and even cancer, the researchers say. A description of the work will be published July 15 in the journal Science Signaling. "Our goal is to build artificial cells...

A new study led by scientists at the University of Pennsylvania School of Veterinary Medicine has painted a clearer picture of the delicate arms race between the human immune system and a pathogen that seeks to infect and kill human cells. The research explores the strategies by which the bacterial pathogen Yersinia, responsible for causing plague and gastrointestinal infections, tries to outsmart immune cell responses and looks at the tactics used by the immune system to fight back....

Unlocking The Secrets Of Death In A Long-Lived Individual's Blood

Lawrence LeBlond for redOrbit.com - Your Universe Online They say that only two things in life are certain: death and taxes. For the former, a new study of the blood of one of the world’s oldest women has offered clues to not only why death occurs, but may also unlock some of the secrets of longevity. Hendrikie van Andel-Schipper, who was born in 1890 and lived to the ripe old age of 115, was at the time of her death in 2005 the oldest person in the world. But as astonishing as that...

Scientists have uncovered a new way the immune system may fight cancers and viral infections. The finding could aid efforts to use immune cells to treat illness. The research, in mice, suggests that some organs have the immunological equivalent of “neighborhood police” – specialized squads of defenders that patrol only one area, a single organ, instead of an entire city, the body. Scientists at Washington University School of Medicine in St. Louis have shown that the liver, skin...

New Italian data uncover specific association between diet and blood cell markers of heart attack- and stroke-associated inflammation WASHINGTON, March 31, 2014 /PRNewswire-USNewswire/ -- New research further illuminates the heart-healthy benefits of the Mediterranean diet, tying the eating plan to lower levels of platelets and white blood cells, two markers of inflammation. Inflammation has an association with greater risk of heart attack and stroke. Study results are published...

Sharon Parmet, University of Illinois at Chicago Researchers at the University of Illinois at Chicago have developed a system for precisely delivering anti-inflammatory drugs to immune cells gone out of control, while sparing their well-behaved counterparts. Their findings were published online Feb. 23 in Nature Nanotechnology. The system uses nanoparticles made of tiny bits of protein designed to bind to unique receptors found only on neutrophils, a type of immune cell engaged in...

Newborns are more susceptible to infections, presumably because of their immature and inexperienced immune systems. The most common dangerous condition in newborns and infants are lower respiratory tract infections caused by viruses, especially respiratory syncytial virus (RSV). A study published on February 13th in PLOS Pathogens shows how the immune system in the lungs during early life differs from the one in older children and adults. Ideally, newborns could be protected against RSV by...

A well-documented suppressor of immunity that's used by fetuses and tumors alike, just may be able to change its spots, researchers report. In the face of a significant bacterial infection, for example, indoleomine 2,3-dioxegenase, or IDO, also appears capable of helping key immune cells called macrophages produce inflammation to destroy the invader, said Dr. Tracy L. McGaha, immunologist at the Medical College of Georgia at Georgia Regents University and GRU Cancer Center. The...

TB Bacteria Hide Their Identity To Invade Into Deeper Regions Of The Lungs
2013-12-20 14:30:54

University of Washington Cell surface lipids hide molecular patterns that infection-killing cells might recognize as dangerous TB-causing bacteria appear to mask their identity to avoid recognition by infection-killing cells in the upper airways. The bacteria call up more permissive white blood cells in the deeper regions of the lungs and hitch a ride inside them to get into the host's body. Details on this finding are reported Dec. 16 in the advanced online edition of the journal...

A ringside seat in the war against infection When golden staph enters our skin it can identify the key immune cells and 'nuke' our body's immune response. Now we know how, thanks to an international research group led by dermatologists from the Centenary Institute and the University of Sydney. Using state-of-the art microscopy techniques, the team identified the key immune cells that orchestrate the body's defenders against invading golden staph, and also how the bacteria can target...
