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

... those particular monomers might, or might not, be involved in the evolution of fibrils, They can thus develop a better understanding of amyloid aggregation. The scientists are also seeking the precise point during fibril formation when interactions between monomers become irreversible. Defining that point i...

Falling ants glide back to trunk to avoid dangers of forest floor

...d information about what kinds of morphologies are involved in the transition from just parachuting, or just falling uncontrolled, to being able to control where you land," Yanoviak said. The gliding behavior would be a definite advantage for ants, like Cephalotes, that forage at the outer reaches of branche...

Scientists discover that host cell lipids facilitate bacterial movement

...ipids attract and modify the functions of proteins involved in regulating actin assembly. PIP2 and PIP3 also prevent capping proteins from binding to the ends of actin filaments, allowing new actin filament assembly. Because Listeria is capable of stimulating actin assembly and PIP2 and PIP3 are known to loc...

VCU Researchers Identify Networks Of Genes Responding To Alcohol In The Brain

...dditional pathway found to be regulated by alcohol involved a nerve growth factor called Bdnf. Bdnf is found in the brain and is a vital part of nervous system development. "We found that the interaction between the Bdnf gene and several other genes that interact with Bdnf were all regulated in one region of...

How an AIDS-Related Cancer Unleashes Inflammation

Developing countries ?where HIV treatments are not readily available ?will be most likely to benefit from potential new treatments for KS that involve inhibiting cytokine production, Ganem said. “KS has become a less u...

Multiple Campylobacter Genomes Sequenced

...mpylobacter species in genes that are likely to be involved in aspects of bacterial virulence, such as adherence, motility, and toxin formation, are all detailed by Fouts et al., who also describe a new putative Campylobacter virulence locus. Further work is needed to relate these genomic differences to funct...
