[ Watch The Video: ScienceCasts: Fruit Flies On The International Space Station ] Laura Niles, NASA Before you swat away the next fruit fly, consider instead just how similar its biological complexities are to our own. In a study published in PLOS ONE, researchers led by Deborah Kimbrell, Ph.D., at the University of California, Davis (UC Davis) and their collaborators, studied how microorganisms may alter fruit flies’ immunity in space and in hypergravity, or increased gravity. The...

Researchers Study Allergic Reactions To Cat Dander
2013-07-25 11:16:22

Michael Harper for redOrbit.com - Your Universe Online Good news for those allergic to cats: New research from the University of Cambridge has helped unlock some of the long-standing mysteries behind allergic reactions to cat dander. The British research team has discovered which biological toxin and receptors are responsible for triggering an extreme reaction to the combination of a cat's skin flakes and saliva. It had been previously shown that a protein found in dander called Fel D 1...

Long-sought Vaccines For Deadly Parasite Closer To Reality According To New Study
2012-12-13 14:18:47

Cell Press [ Watch The Video ] One major cause of illness from food-borne diseases is the parasite Toxoplasma gondii (T. gondii). New insights into how the immune system combats T. gondii are provided in a study published by Cell Press December 13th in the journal Immunity. The findings could lead to the development of long-sought vaccines to protect against T. gondii and related parasites. To fight off pathogens, the immune system relies on Toll-like receptors (TLRs)–a class...

Team develops first 3D look at interaction between immune sensor and protein that helps bacteria move To invade organisms such as humans, bacteria make use of a protein called flagellin, part of a tail-like appendage that helps the bacteria move about. Now, for the first time, a team led by scientists at The Scripps Research Institute and Sanford-Burnham Medical Research Institute has determined the 3D structure of the interaction between this critical bacterial protein and an immune...

Two out of every thousand babies are at risk of brain damage in connection with birth. Researchers at the Sahlgrenska Academy at the University of Gothenburg, Sweden, have identified mechanisms behind these injuries, which could lead to better treatment and a richer life for the infants affected. Roughly two in every thousand babies are at risk of suffering brain damage as a result of events before, during and after delivery. Infections in the blood or a reduced supply of oxygen and blood can...

It may have been 1 billion years since plants and animals branched apart on the evolutionary tree but down through the ages they have developed strikingly similar mechanisms for detecting microbial invasions and resisting diseases. This revelation was arrived at over a period of 15 years by teams of researchers from seemingly disparate fields who have used classical genetic studies to unravel the mysteries of disease resistance in plants and animals, according to a historical overview that...

High fat diets cause a dramatic immune system overreaction to sepsis, a condition of systemic bacterial infection. An experimental study in mice, published in the open access journal BMC Physiology, has shown that a diet high in saturated fat, sugars and cholesterol greatly exaggerates the inflammatory response to sepsis. Chantal Rivera, PhD Associate Professor of Molecular and Cellular Physiology at Louisiana State University Health Sciences Center-Shreveport, said that "Mortality due to...

La Jolla, CA, June 20, 2005 - Scientists at The Scripps Research Institute have solved the structure of a crucial human immune system molecule called TLR3, an acronym for Toll-like receptor three. In an upcoming issue of the journal Science, the protein is described as a large horseshoe-shaped coil composed of 23 leucine-rich repeats (LRRs). The structure reveals details of TLR3 that have never been seen before, an essential step toward fully understanding the critical role this...


Word of the Day
cenobite
  • One of a religious order living in a convent or in community; a monk: opposed to anchoret or hermit (one who lives in solitude).
