Weizmann Institute scientists reveal a new mechanism for keeping inflammation in check The molecular machines that defend our body against infection don't huff and puff, but some of them apparently operate on the same principle as a steam engine. Weizmann Institute scientists have discovered a mechanism that controls inflammation similarly to a steam-engine valve: Just when the inflammatory mechanism that protects cells against viruses reaches its peak of activity, the molecular...

Most degenerative diseases begin with a gradual loss of specific cell types that progresses, eventually leading to symptoms. For example, in type I diabetes, hyperglycemia commonly develops when approximately 80 percent of the beta cells in the pancreas are lost; in Parkinson's disease, motor dysfunction typically begins when neurons in a certain portion of the brain are decreased by 70 to 80 percent. Finding ways to stop early cell destruction is vital, but methods to do so have proven...

Cell biologists pondering the death of neurons "” brain cells "” said today that by eliminating one ingredient from the cellular machinery, they prolonged the life of neurons stressed by a pesticide chemical. The finding identifies a potential therapeutic target to slow changes that lead to neurodegenerative disorders such as Parkinson's and Alzheimer's diseases. The researchers, from The University of Texas Health Science Center San Antonio, found that neurons lacking a substance...

Neurodegenerative diseases like Alzheimer's and Parkinson's are partly attributable to brain inflammation. Researchers at Karolinska Institutet now demonstrate in a paper published in Nature that a well-known family of enzymes can prevent the inflammation and thus constitute a potential target for drugs. Research suggests that microglial cells - the nerve system's primary immune cells - play a critical part in neurodegenerative diseases, such as Alzheimer's and Parkinson's. The...

An enzyme viewed as an executioner, because it can push cells to commit suicide, may actually short circuit a second form of cell death, researchers at Emory University School of Medicine have discovered. The finding could shift drug discovery efforts, by leading scientists to rethink how proposed anti-cancer and anti-inflammatory drugs that target the enzyme, called caspase 8, are supposed to work. The results are online this week and will be published in the March 17th edition of Nature....

Work led by St. Jude Children's Research Hospital investigators provides fresh insight into mechanisms controlling programmed cell death pathways and offers new targets in the fight against cancer and virus-infected cells Work led by St. Jude Children's Research Hospital scientists identified how cells flip a switch between cell survival and cell death that involves a protein called FLIP. The findings solve a riddle that has puzzled scientists for more than a decade regarding the dual nature...

Hepatocellular carcinoma (HCC) is the fifth most common malignancy in the world and is estimated to cause approximately half a million deaths annually. Undoubtedly, the best available treatment for all liver tumors is complete surgical resection. However, the synthetic somatostatin analogue octreotide has been found effective in inhibiting tumor growth in a variety of experimental models. It has been reported that octreotide inhibits the proliferation and induces apoptosis of different HCC...

Cardiologists at the University of Connecticut Health Center have identified a protein fragment that when detected in the blood can be a predictor of heart attack. Their research, led by Dr. Bruce Liang, director of the Pat and Jim Calhoun Cardiology Center, is published in the January 11 issue of the Journal of the American College of Cardiology. It found heart attack patients had elevated levels of the protein fragment known as Caspase-3 p17 in their blood. "We've discovered a new biomarker...
