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 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...

Our Immune System May Actually Help Staph Bacteria Thrive: Study

Ranjini Raghunath for redOrbit.com - Your Universe Online Staphylococcus aureus, one of many strains of bacteria involved in Staph infections, is found in about 20 percent of all humans. Under normal conditions, the bacterium dwells harmlessly in the skin or nasal passages, occasionally causing food poisoning or mild skin infections. When it enters the bloodstream, however, it can be quite deadly, causing life-threatening illnesses such as meningitis or sepsis. One of the ways the...

-Alveolar macrophage (AM) function plays a critical role in protecting the lungs by removing particulates. -Chronic drinking causes persistent oxidative stress in the lungs, leading to impaired AM function. -A new rodent study shows that chronic drinking appears to intensify lung damage caused by particulate matter. Alveolar macrophage (AM) function plays a critical role in protecting the lungs from particulate matter inhalation by removing particulates from the airway and secreting...

Macrophages Key In Salamander Regeneration
2013-05-21 15:06:03

Brett Smith for redOrbit.com - Your Universe Online For years, scientists have considered salamanders the ℠Holy Grail´ of biological regeneration. Now, a new study in the Proceedings of the National Academy of Sciences has revealed an exciting step forward in the quest to adapt this ability for medical use in humans. Based on experiments with the tiny amphibians, researchers from the Australian Regenerative Medicine Institute at Monash University have found that elements of a...

Potential approach to treating atherosclerosis and other chronic inflammatory diseases A multicenter team of researchers, including scientists at Columbia University Medical Center (CUMC), Brigham and Women's Hospital (BWH), Mount Sinai School of Medicine, and Massachusetts Institute of Technology, has developed biodegradable nanoparticles that are capable of delivering inflammation-resolving drugs to sites of tissue injury. The nanoparticles, which were successfully tested in mice, have...

The theory that pigeons' famous skill at navigation is down to iron-rich nerve cells in their beaks has been disproved by a new study published in Nature. The study shows that iron-rich cells in the pigeon beak are in fact specialized white blood cells, called macrophages. This finding, which shatters the established dogma, puts the field back on course as the search for magnetic cells continues. "The mystery of how animals detect magnetic fields has just got more mysterious" said Dr...

University of Texas Medical Branch at Galveston researchers have discovered previously unsuspected aspects of the guidance system used by the body's first line of defense against infection. The new work focuses on the regulation of immune response by two forms of the signaling molecule IL-8, as well as IL-8's interaction with cell-surface molecules called glycosaminoglycans (or GAGs for short). Infected or injured tissues release IL-8 to attract bacteria- and virus-killing white blood...

Scientists at the University Medical Center in Mainz prove multiple DNA repair defect in monocytes Scientists working with Professor Bernd Kaina of the Institute of Toxicology at the Medical Center of Johannes Gutenberg University Mainz have demonstrated for the first time that certain cells circulating in human blood — so-called monocytes — are extremely sensitive to reactive oxygen species (ROS). They were also able to clarify the reason for this: ROS are aggressive forms of...

A study from scientists at Queen Mary, University of London, sheds new light on why people who experience serious trauma or go through major surgery, can suffer organ damage in parts of the body which are seemingly unconnected to the injury. The study, published today in Nature Immunology*, examines the way certain white blood cells, called neutrophils move out of blood vessels to defend damaged organs against injury or infection. This is normally a one-way journey but researchers were...


Word of the Day
call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
