How sneaky HIV escapes cells

... initially developed exosomes as a quality control mechanism to get rid of clumped proteins, which are generally broken and useless. However, just as retroviruses exploit other cell processes for their own ends, it now appears they rely on exosomes to get out of infected cells and infect fresh cells. As such,...

Molecular motors may speed nutrient processing

...before they can enter the cell; that it provides a mechanism for altering the composition of the microvillar surface to handle changes in "what comes down the pipe;" and that it serves a role in cell-cell communication by launching vesicles that contain signaling proteins.

Story ideas from the Journal of Biological Chemistry

...osis Researchers have discovered a new cellular mechanism that may better explain what causes amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's Disease. ALS is characterized by the death of neurons that control voluntary muscles, leading to muscle weakness and atrophy. Around 25 percent of t...

A first -- Hebrew University scientist observes brain cell development in 'real time'

...le of continuous change. This method provides a mechanism for observing, for the first time in a mammal, how a neuron develops into a rich and complex cell and how, once developed, neurons are maintained in the highly active and changing environment of the brain. As for further research that some day cou...

New adult brain cells may be central to lifelong learning

...eurogenesis may represent not merely a replacement mechanism for lost neurons, but instead an ongoing developmental process that continuously rejuvenates the mature nervous system by offering expanded capacity of plasticity in response to experience throughout life."...

Jet lag: It's all about chemical reactions in cells

... and Dartmouth researchers explains the biological mechanism behind how circadian clocks sense light through a process that transfers energy from light to chemical reactions in cells. The research is published in the May 18 issue of the journal Science. Circadian clocks in cells respond to differences in light...

Parkinson's protein protects neurons from stress induced cell death

...of Neuroscience", the protein activates a survival mechanism which had been known for its prominent role in immune response. Usually, Parkinsons disease occurs after the age of 50 and in Germany about 400,000 people are affected. It is characterized by a decline of neurons in the so-called Substantia Nigra,...

Repair of DNA by Brca2 gene prevents medulloblastoma

... showed that the Brca2 gene acts as a surveillance mechanism that triggers repair of DNA that is damaged when the cell makes a duplicate set of its chromosomes each time it divides," said Peter McKinnon, Ph.D., associate member of the Genetics and Tumor Cell Biology department at St. Jude. "The enormous rate o...

Hyperactivity and academic achievement could be linked by genetics

"Whatever the mechanism responsible, the finding of substantial genetic overlap between hyperactivity and achievement has important implications for research searching for genes associated with the two behaviors," according to Kimberly J. Saudino, associate professor of psy...

Researchers said today they have identified the mechanism of action of lipoic acid, a remarkable compound that in animal experiments appears to slow down the process of aging, improve blood flow, enhance immune function and perform many other functions. The findings, discussed at the "Diet and Optimum Hea...

Genome of yellow fever/dengue fever mosquito sequenced
