Immunology

Rapid recall to fight familiar foes

The immune system's first encounter with a potential threat is a valuable learning experience. Through a process of genetic recombination, our immune B cells can potentially produce a wide array of B cell receptor (BCR) molecules, ...

Copper identified as culprit in Alzheimer's disease

Copper appears to be one of the main environmental factors that trigger the onset and enhance the progression of Alzheimer's disease by preventing the clearance and accelerating the accumulation of toxic proteins in the brain. ...

Researchers identify 'switch' for long-term memory

Neurobiologists at Heidelberg University have identified calcium in the cell nucleus to be a cellular "switch" responsible for the formation of long-term memory. Using the fruit fly Drosophila melanogaster as a model, the ...

Genetics

Researchers discover new mechanism for human gene expression

In a study that could change the way scientists view the process of protein production in humans, University of Chicago researchers have found a single gene that encodes two separate proteins from the same sequence of messenger ...

Researchers discover new proteasome regulatory mechanism

Dysfunction of the ubiquitin-proteasome system (UPS) has been detected in many neurodegenerative diseases, such as Alzheimer's and Parkinson's diseases, and certain types of cancer. Such dysfunction is also believed to be ...
