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

...e uncovered how the innate immune system in mice's brains fights viral infection of neurons. The findings, published as the cover study in the latest issue of Virology, show that proteins in neurons fight the virus at multiple stages--by preventing the formation of viral RNA and proteins, and blocking the v...

Protein Packages Found To Activate Genes; May Be What Regulates Development And Disease

...volved in the assembly of organs and tissues, like brains and muscles, into a complex living organism. HOX genes are also vital for understanding the way that people get certain cancers. "Many of the proteins that regulate these genes can suppress or enhance tumor growth," Bernstein notes. "Some of the gen...

First 'atlas' of key brain genes could speed research on cancer, neurological diseases

...more than 1,000 of these TF’swere expressed in the brains of developing mice.Using genetic probes to investigate thin sections of mouse brains, thescientists found that only 349 of the TF genes were expressed inspecific regions, and not throughout the brain, as the majority were.They inferred that these 349...

Gene Therapy For Parkinson's Disease Moves Forward In Animals

Alcohol's effects on gene expression in the central nervous system

...t of more than 50,000 ?are turned on or off in the brains of alcoholics," he said. "Microarray studies ?the examination of a small glass microscope slide that has thousands of different DNA samples attached to it ?that are applied to brain function are just beginning in the field of alcoholism. Several year...

First real-time view of developing neurons reveals surprises, say Stanford researchers

...ably these same processes are happening in our own brains all the time," Niell said. When people learn new skills or add memories to their overstuffed brains, new connections are required to retain that information. Some diseases also seem to be caused by brain connections not forming normally. Dyslexia, f...

New insight into people who 'see' colors in letters and numbers

...ctional magnetic resonance imaging (fMRI) of their brains reveals that they show activation of color-perception areas. The researchers said their findings lend support to the hypothesis that the condition is due to cross-activation between adjacent brain areas involved in perceiving shapes and colors. Some...

Duke Chemists Isolating Individual Molecules Of Toxic Protein In Alzheimer's, Parkinson's Disease

...chemistry of formation of these fibrils within the brains of humans and other animals, said Akhremitchev, who is an assistant professor of chemistry. In the brain, "monomers of all kinds are suspended in a soup in equilibrium," he said. Given that the components of amyloid fibrils measure only billionths o...

Carnegie Mellon scientists develop tool that uses MRI to visualize gene expression in living animals

...ted the vector carrying the MRI reporter gene into brains of living mice and imaged the MRI reporter expression periodically for over a month in the same cohort of animals. The research showed no overt toxicity in the mouse brain from the MRI reporter. ...

Cricket's finicky mating behavior boosts biodiversity

...f biodiversity. "Animals with nervous systems and brains have preferences and can make choices," says Tamra Mendelson, an evolutionary biologist at Lehigh. "Changes in these preferences and choices appear to drive speciation. "That raises the question: Can something seemingly so individual as a choice hav...

Wisconsin researchers identify sleep gene

...s look different that they do in flies because our brains are organized differently," Cirelli says. "But the EEGs showed electrophysiological changes signifying that the flies were asleep and awake." In mammals the changes produce hallmark waves, or oscillations of groups of neurons, easily detected by EEG...

New component of the 'brakes' on nerve regeneration found

...led that TAJ/TROY is produced throughout the adult brains of mice. Also, they found that TAJ/TROY readily fits into the inhibitory receptor complex and that the resulting receptor complex switches-on the inhibitory machinery within neurons. Also, they found that treating neurons with a nonfunctional version...

Birds brains reveal source of songs

...birds may have something to teach us about our own brains and what we learn may eventually apply to human diseases that affect motor abilities, such as Parkinson's disease. "The question we're trying to answer is how a young bird learns its song," says Professor Michale Fee of MIT's McGovern Institute abou...

Strongest proof yet found for prion hypothesis

... the test tubes. These were then injected into the brains of healthy hamsters, which began showing TSE symptoms within four months and, on average, died less than six months after inoculation. "For many years, people have tried to make these infectious prions in test tubes, because what is needed to prove ...

Love's all in the brain: fMRI study shows strong, lateralized reward, not sex, drive

.... They detected quantifiable love responses in the brains of 17 young men and women who each described themselves as being newly and madly in love. The multidisciplinary team found that early, intense romantic love may have more to do with motivation, reward and "drive" aspects of human behavior than with ...
