NYU Study Reveals How Brain's Immune System Fights Viral Encephalitis

...sensitive to the protective effect of interferons, inducing pathways to fight the virus' spread. However, their findings showed that interferons fight the virus at different stages of the virus' life cycle. First, they inhibit viral RNA and protein synthesis. If this fails, interferons block the virus from fo...

Critical role in programmed cell death identified

...words, blocking fragmentation prevents cell death, inducing fragmentation provokes cell death. "This programmed cell death is so important and the more players we know that are involved, the more potential targets we have for therapeutics," Conradt said. During development, for example, many neurons are buil...

Deficiency of growth hormone and IGF-1 reduces cancer and kidney disease, but creates other problems

...uld be substantially decreased in these animals by inducing a modest deficiency of growth hormone and IGF-1 early in life. However, there is a tradeoff and deficiency of growth hormone and IGF-1 may impair learning and memory and accelerate some degenerative diseases. ...

How an AIDS-Related Cancer Unleashes Inflammation

...many genes in the viral genome that are capable of inducing cytokine production, the mechanism underlying this induction has remained unknown," said Ganem. In their studies, McCormick and Ganem concentrated on one protein called kaposin B, which was discovered in Ganem's laboratory, but whose function remain...

To Stop Evolution: New Way Of Fighting Antibiotic Resistance Demonstrated By Scripps Scientists

...whose sole task is to make mutations. Presumably, inducing mutations is an effective evolutionary strategy for dealing with environmental changes that maximize the chances that a progeny cell will be better adapted. In order to evolve, organisms have to mutate, so they turn on the mutation process when they ...

Experiment station researchers to explore genome of disease-fighting fungus

...he root system." Finding unique genes involved in inducing plant resistance could also aid the greenhouse industry that encounters problems with seedling rot in different plant varieties. "In the nursery industry where you transplant from smaller to larger containers, you can incorporate the fungus as a pot...

Study Finds Moderate Hypothermia A Safe Treatment For Traumatic Brain Injury In Kids

...l body temperature (36.5-37.5 degrees Celsius). By inducing hypothermia in pediatric patients down to 32 degrees Celsius, doctors found that hypothermia tended to reduce mortality, lower the severity of intracranial hypertension during the cooling phase and has the potential to improve the functional outcome ...

Study: Harmless virus kills some cancers

...cells also disrupting their ability to survive and inducing cell death," Meyers said. "Although we suspect it is, more studies are needed to determine if the mechanism through which AAV2 destroys cancer cells is the same." Scientists often refer to cancer cells as deregulated, meaning they are no longer acti...

Using a fragment-based approach based on assays conducted with highly sensitive nuclear magnetic resonance ("NMR") techniques developed in Dr. Pellecchia's laboratory, the scientists were able to identify a scaffold that served as a temp...

Gifts from the sea

... of eggs can be harvested from a single female. By inducing the clam eggs to undergo cell division at the same time, scientists can study millions of cells in the same stage of division. Clam eggs are also transparent, providing a perfect window on biology in action. MBL scientists studying surf clams have ma...

Mechanism regulating tooth shape formulation found

...eeth that lack ectodin with excess amounts of cusp inducing protein (bone morphogenetic protein or BMP). Whereas teeth producing ectodin develop quite normally with excess BMP, teeth without ectodin had a markedly accelerated induction of cusps. Indeed the researchers were able to induce cusps and mineralizat...

Cells direct membrane traffic by channel width

...hers believed the channels could be manipulated by inducing the surrounding amino acids to create a hydrophobic or semi-hydrophobic lining required for glycerol passage. Success in doing so could have created new targets for drug therapies. However, it turns out, the amino acids are the same around both chan...

This helps jump-start the immune response to break tolerance. But, why Listeria over other bacteria as a vehicle to deliver a tumo...
