Understanding amyloid-beta's normal function could lead to preventive, therapeutic strategies Amyloid-beta protein "“ the primary constituent of the plaques found in the brains of Alzheimer's disease patients "“ may be part of the body's first-line system to defend against infection. In their report in the March 3 issue of the open-access journal PLoS One, a team led by Massachusetts General Hospital (MGH) researchers describe their evidence that amyloid-beta protein (A-beta) is...

Study shows: Nutrition has a direct influence on the immune system Bonn researchers have discovered an elementary mechanism which regulates vital immune functions in healthy people. In situations of hunger which mean stress for the body's cells, the body releases more antimicrobial peptides in order to protect itself. The scientists will publish their results in the journal Nature. T cells, B cells, antibodies are known as the 'SWAT team' of our immune system that intervenes when viruses and...

New research in the Journal of Leukocyte Biology shows that glycyrrhizin extracted from licorice root helps the body defend against Pseudomonas aeruginosa infection As it turns out, children were not the only ones with visions of sugar plums dancing in their heads over this past holiday season. In a new research report published in the January 2010 issue of the Journal of Leukocyte Biology (http://www.jleukbio.org), a team of scientists from the University of Texas Medical Branch and Shriners...

LUND, Sweden, December 2 /PRNewswire/ -- DermaGen AB - part of the Karolinska Development dermatology and wound healing company "Pergamum" - today announced that Dermagen AB has received promising results from a clinical Phase I/IIa study. DermaGen AB is developing a novel antimicrobial peptide (AMP) treatment for atopic dermatitis. Atopic dermatitis is a chronic inflammatory skin disease where dry skin and the skin's weakened barrier function make patients susceptible to colonization by...

 A new study has concluded that one key part of the immune system, the ability of vitamin D to regulate anti-bactericidal proteins, is so important that is has been conserved through almost 60 million years of evolution and is shared only by primates, including humans "“ but no other known animal species.The fact that this vitamin-D mediated immune response has been retained through millions of years of evolutionary selection, and is still found in species ranging from squirrel...

U.S. scientists have found exposure to estrogen reduces the production of immune-related proteins in fish, making them more susceptible to disease. U.S. Geological Survey researchers Laura Robertson, Luke Iwanowicz and Jamie Marie Marranca said their findings provide new clues for why intersex fish, fish kills and fish lesions often occur together in the Shenandoah and Potomac rivers. The study, led by Robertson, revealed largemouth bass injected with estrogen produced lowered levels of...

Exposure to estrogen reduces production of immune-related proteins in fish. This suggests that certain compounds, known as endocrine disruptors, may make fish more susceptible to disease.The research may provide new clues for why intersex fish, fish kills and fish lesions often occur together in the Shenandoah and Potomac rivers. The tests were conducted in a lab by scientists from the U.S. Geological Survey.The study, led by USGS genomics researcher Dr. Laura Robertson, revealed that...

Researchers at the University of British Columbia have discovered a mimic of one of "nature's antibiotics" that can be used to coat medical devices to prevent infection and rejection. The study, released today in the journal Chemistry and Biology, found that a synthetic form, short tethered cationic antimicrobial peptides (peptide), can protect surfaces, like those of medical devices, killing bacteria and fungi that come into contact with them. Peptides are small proteins. Medical devices...
