A case of mistaken molecular identity

...rasite but also cause damage to heart cells. Levin suspected "molecular mimicry" as the cause of the misguided attack. Molecular mimicry occurs when a molecule that is part of an infectious agent resembles a molecule native to the body. Eventually, the immune system begins to mistake the native molecule for th...

Any pathogen whose genetic information is contained in online genetic databases represents a suitable potential target. This makes the technique ideal for sit...

Most human-chimp differences due to gene regulation ?not genes

...ed only in humans." "For 30 years scientists have suspected that gene regulation has played a central role in human evolution," said Kevin White, Ph.D., associate professor of genetics and ecology and evolution at Yale and senior author of the study. "In addition to lending support to the idea that changes in...

U-M researchers take new approach to defeating Gram-negative bugs

...s an easy target for antibiotics. Because Woodard suspected he might be flying in the face of conventional wisdom on bacteria, he solicited second opinions from the Borstel Research Center in Germany, which does a good deal of work on Gram-negative bacteria. Scientists there were initially skeptical, he said,...

Molecular mechanism may explain how fevers spark seizures

...in's excited chatter. GABA-A receptors were long suspected to play a role in epilepsy because they are the major inhibitory receptors in the brain and might therefore dampen the hyperexcitability that characterizes seizures. Phenobarbital and other barbiturate drugs and anti-anxiety drugs like Valium exert t...

Oops! Researchers publish new findings on the brain's response to costly mistakes

...olved with emotional responses, and scientists had suspected it might also be involved in response to costly errors. But this is the first brain-imaging study to test that idea. Interestingly, the U-M team had previously shown that the rACC area became much more active in response to a no-penalty error in the...

Mice lacking social memory molecule take bullying in stride

...Press/prbdnf.cfm ). Berton, Nestler and colleagues suspected that BDNF plays a similarly pivotal role in social learning. To find out, they first subjected mice to a different dominant mouse daily for 10 days. Even 4 weeks later, the "socially defeated" animals vigorously avoided former aggressors or unfami...

He and his colleagues have been mapping the activity of dozens of miRNAs in various types of normal and malignant tissues for several years. Earlier studies showed ...

Study by Einstein researchers could lead to a novel strategy for treating obesity

...ite. The study focused on malonyl CoA, a molecule suspected of being one of the critical nutrients influencing hypothalamic regulation of eating behavior. Previous studies had shown that hypothalamic levels of malonyl CoA increase markedly after meals and are suppressed by fasting. The Einstein researchers ...

"Many scientists had suspected a relationship between cellulose synthase and microtubules, but the exact nature of the interaction was hard to pinpoint," Ehrhardt said. "The microtubules act as more than a general scaffold for organizing the cell wall; individual elements of the m...

Utah researchers confirm chromosome may harbor autism gene

...o the gene that causes the syndrome, U researchers suspected FXR1 might be linked to autism. But after analyzing the entire coding sequence of FXR1, the researchers found no alterations in the gene likely to contribute to autism. Based on statistical evidence, they're now looking at other genes. But evidence ...

Invasive species harms native hardwoods by killing soil fungus

To test this possibility, they collected soil from five forests in Ontario dominated by four species of native hardwoods. First, the researchers tested seedlings' ability to form myc...
