Disruption of normal gene interaction linked to schizophrenia

Disruption of the normal interaction between the genes PRODH and COMT contributes directly to major symptoms of schizophrenia by upsetting the balance of the brain chemicals glutamate and dopamine, according to a group of investigators that includes a scientist now at St. Jude Children's Research Hospital.

Protein target for Parkinson's disease

Researchers at Johns Hopkins' Institute for Cell Engineering (ICE) have discovered a protein that could be the best new target in the fight against Parkinson's disease since the brain-damaging condition was first tied to loss of the brain chemical dopamine.

Chronic stress induces rapid occlusion of angioplasty

Chronic stress can induce rapid blocking of arteries after a balloon angioplasty procedure, according to research performed in animal studies at Georgetown University Medical Center. Blocked coronary arteries after angioplasty affect 41 percent of patients who undergo the procedure and can lead to death.

New method to discover links between cellular machines

Most of what happens in cells is the work of machines that contain dozens of molecules, chiefly proteins. With the completion of human and other genomes, researchers now have a nearly complete "parts list" of such machines; what's lacking now is the manual telling where all the pieces go.

Nanotechnology and biochemistry provide new way to study T cell signaling

Researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California at Berkeley, combining nanotechnology with biochemistry, have created unique synthetic membranes that, for the first time ever, enable them to directly control signaling activity in living T cells from the immune system. Already their experiments have yielded surprising results.
