Study of glial cells in the roundworm C. elegans may provide insight into a variety of human brain diseases

The key to understanding our brains may lie within a one-millimeter long worm, new research from Rockefeller University indicates. Reporting in the June issue of Developmental Cell, Shai Shaham, Ph.D., and graduate student Elliot Perens use the roundworm, C. elegans, to investigate the mysterious glial cell, which makes up 90 percent of the human brain and, when it malfunctions, can contribute to diseases like Parkinson's disease and schizophrenia.

Experimental drug therapy could open new window for treatment of deadly stroke

A new type of drug therapy that is currently being tested in Canada could significantly reduce the death rate caused by the deadliest form of stroke. According to the Canadian Heart and Stroke Foundation, new developments in stroke research make it more important than ever that Canadians recognize and react to the warning signs of stroke.

Research opens up new directions for studying prion diseases in humans

The mysterious, highly infectious prions, which cause the severe destruction of the brain that characterizes "mad cow disease" and several human brain degenerative disorders, can be rendered harmless in the laboratory by a slight alternation of the three-dimensional conformation or shape of the prion protein's structure.
