Bacterial toxins activate fat cells producing chronic inflammation, which in turn boosts risk of developing diabetes Making fat cells immortal might seem like a bad idea to most people, but for a team of University of Iowa scientists it was the ideal way to study how the interaction between bacteria and fat cells might contribute to diabetes. The connection between fat, bacteria, and diabetes is inflammation, which is the body's normal reaction to infection or injury. Inflammation is...

Researchers Study Allergic Reactions To Cat Dander

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...

How Does The Immune System React To Toxins In Space?

April Flowers for redOrbit.com - Your Universe Online A small device in the payload of the space shuttle Atlantis that housed a set of biological samples was the target of a team of eager US Army researchers when the shuttle touched down at Cape Canaveral in the summer of 2011. The mission was the end of the shuttle program, but the beginning of two years of study on those samples. The team presented their results at the Experimental Biology 2013 conference this past week in Boston,...

The novel Natural Sciences Bibliographic Web Portal aims to provide comprehensive bibliographic information on the basic and applied life, earth and health sciences. While the site was released to the public one week ago it has and has just included the two new sections Lipopolysaccharide and Muscle. While the publishers target to publish a total of over 21 million references until 2014, the site currently contains 225,000 posts, increasing by 25,000 items every day. These references contain...

New research published in the Journal of Leukocyte Biology suggests complement system activation is initiated by receptors on the inside and outside of immune cells using unique and shared pathways A new research report in the October 2010 print issue of the Journal of Leukocyte Biology (http://www.jleukbio.org) sheds important light on how our immune systems detect invading organisms to be destroyed and removed from our bodies. The information from this research should ultimately help lead...

Scientists have combined chemistry and biology research techniques to explain how certain bacteria grow structures on their surfaces that allow them to simultaneously cause illness and protect themselves from the body's defenses. The researchers are the first to reproduce a specific component of this natural process in a test tube "“ an essential step to fully understanding how these structures grow. With the new method described, these and other researchers now can delve even deeper...

Researchers have new evidence to explain how saturated fatty acids, which soar in those who are obese, can lead the immune system to respond in ways that add up to chronic, low-grade inflammation. The new results could lead to treatments designed to curb that inflammatory state, and the insulin resistance and type 2 diabetes that come with it. One key, according to the report in the November Cell Metabolism, a Cell Press publication, is an immune receptor (called Toll-like receptor 4 or Tlr4)...

Researchers have uncovered why some dietary fats, specifically long-chain fats, such as oleic acid (found in olive oil), are more prone to induce inflammation. Long-chain fats, it turns out, promote increased intestinal absorption of pro-inflammatory bacterial molecules called lipopolysaccharides (LPS). This study appears in the January issue of JLR.While dietary fats that have short chains (such as those found in milk and cheese products) can be absorbed directly into the bloodstream from...

Compugen has announced positive results from a recently completed in vivo study of CGEN-25007, a novel peptide antagonist of the gp96 protein. Using an animal model of endotoxemia, a condition in which there is a substantial increase in the levels of inflammatory cytokines and chemokines in serum, CGEN-25007 was shown to exhibit a profound and dose-dependent anti-inflammatory activity. In this study, the novel peptide was administered following the introduction of lipopolysaccharide (LPS),...
