The specific mechanisms by which humans and other animals are able to discriminate between disease-causing microbes and innocuous ones in order to rapidly respond to infections have long been a mystery to scientists. But a study conducted on roundworms by biologists at UC San Diego has uncovered some important clues to finally answering that question. In a paper published in this week´s early online issue of the journal Cell Host & Microbe, the researchers discovered that...

Scientists from Queen Mary, University of London have discovered the workings behind some of the bacteria that kill hundreds of thousands every year, possibly paving the way for new antibiotics that could treat infections more effectively. With antibiotic resistance on the rise in strains of pathogenic bacteria, innovative strategies are needed to discover ways of treating bacterial infections in both humans and in agriculture. Writing in the journal PLoS Pathogens, the team from Queen...

This study paves the way for developing toxin antidotes to safeguard public health and national security.  A team of scientists from A*STAR's Institute of Molecular and Cell Biology (IMCB) has discovered the secret recipe for "Ëœantidotes' that could neutralize the deadly plant toxin Ricin, widely feared for its bioterrorism potential, as well as the Pseudomonas exotoxin (PE) responsible for the tens of thousands of hospital-acquired infections in immune-compromised patients...

Toxins produced by plants and bacteria pose a significant threat to humans, as emphasized by the recent effects of cucumber-borne Shiga toxin in Germany. Now, new research published on July 21st by the Cell Press journal Developmental Cell provides a clearer view of the combination of similar and divergent strategies that different toxins use to invade a human host cell. Ricin is a highly toxic protein derived from the castor bean plant that has raised concerns as a potentially lethal...

Several bacterial pathogens use toxins to manipulate human host cells, ultimately disturbing cellular signal transduction. Until now, however, scientists have been able to track down only a few of the proteins that interact with bacterial toxins in infected human cells. Now, researchers of the Max Planck Institute of Biochemistry in Martinsried and the Max Delbrck Center for Molecular Medicine (MDC) Berlin-Buch in Germany have identified 39 interaction partners of these toxins, using novel...


Word of the Day
cruet
  • A vial or small glass bottle, especially one for holding vinegar, oil, etc.; a caster for liquids.
This word is Middle English in origin, and ultimately comes from the Old French, diminutive of 'crue,' flask.
