New research led by the Karolinska Institutet, Sweden and the University of Glasgow, Scotland, has identified a link between a human gene and the composition of human gastrointestinal bacteria. In a study published as a letter to the journal Gut, the team outline new evidence suggesting that the human genome may play a role in determining the makeup of the billions of microbes in the human gastrointestinal tract collectively known as the gut microbiota. Mauro D'Amato, Associate Professor...

Mice carrying a set of friendly microbes that are usually found in humans fail to develop a proper immune system and are left susceptible to illness as a result. The findings in the June 22nd issue of the journal Cell, a Cell Press publication, show that animals have coevolved with and rely on their own very special array of microbial partners. As far as our immune systems are concerned, not just any bug collection will do. "Human microbe-colonized mice have gut immune systems that look...

Trillions of microbes inhabit the human body, occupying virtually every nook and cranny. And most of the time, this relationship is a friendly one, with microbes helping to digest food, strengthen the immune system and ward off dangerous pathogens. But despite their prominent roles, researchers have understood little about which microbes reside in specific sites of the body. Now, a consortium of some 200 U.S. scientists at Washington University School of Medicine in St. Louis and elsewhere...

For the first time a consortium of researchers organized by the National Institutes of Health, including a University of Colorado Boulder professor, has mapped the normal microbial makeup of healthy humans. The team made up of 200 researchers from the Human Microbiome Project Consortium, or HMP, and based at 80 research institutions, reports that while nearly everyone carries pathogens -- which are microorganisms that cause illness -- pathogens cause no disease in healthy individuals....

Early colonization of the gut by microbes in infants is critical for development of their intestinal tract and in immune development. A new study, published in BioMed Central's open access journal Genome Biology, shows that differences in bacterial colonization of formula-fed and breast-fed babies leads to changes in the infant's expression of genes involved in the immune system, and in defense against pathogens. The health of individuals can be influenced by the diversity of microbes...

Each of us carries a unique collection of trillions of friendly microbes in our intestines that helps break down food our bodies otherwise couldn't digest. This relationship between humans and their microbes is generally a healthy one, but changes to the mix of microbes in the digestive tract are suspected to play a role in obesity, malnutrition, Crohn's disease and other ailments. Now, scientists at Washington University School of Medicine in St. Louis show they can grow and manipulate...

The crook of your elbow is not just a plain patch of skin. It is a piece of coveted real estate, a special ecosystem, a bountiful home to no fewer than six tribes of bacteria. Even after you have washed the skin clean, there are still 1 million bacteria in every square centimeter. But these are not bad bacteria. They are what biologists call commensals, creatures that eat at the same table with people to everyone's mutual benefit. Though they were not invited to enjoy board and lodging in...

St. Louis, July 4, 2005 -- Nerves talk to each other using chemicals called neurotransmitters. One of those "communication chemicals," aptly named GABA (gamma amino butyric acid), shows up in unusually high amounts in some aggressive tumors, according to a new study from Washington University School of Medicine in St. Louis. The researchers investigated metastatic neuroendocrine tumors, which include aggressive types of lung, thyroid, and prostate cancers that spread to other parts of the...


Word of the Day
penuche
  • A fudgelike confection of brown sugar, cream or milk, and chopped nuts.
'Penuche' is a variant of 'panocha,' a coarse grade of sugar made in Mexico. 'Panocha' probably comes from the Spanish 'panoja, panocha,' ear of grain.
