Novel FRET biosensor allows measurement of intraorganellar glutathione potentials in living cells

In work published in the June 2011 issue of Experimental Biology and Medicine, Kolossov, Spring and their co-investigators - a multidisciplinary team within the Institute for Genomic Biology at the University of Illinois - have transferred the concept of redox-sensitive Green Fluorescent Proteins (GFPs) to a quantitative F-rster resonance energy transfer (FRET) imaging platform.

Linkam tensile stage chosen to control stress in growth of human collagen by the University of Liverpool

Manufacturers temperature controlled microscopy, Linkam Scientific Instruments, have been chosen by the Physics Department of the University of Liverpool to study the effects of controlling stresses applied during the growth of collagen secreted from human fibroblast cells. The research goal of Senior Research Assistant, Dr Caroline Smith, and her colleagues at the University of Liverpool is to advance the treatment of tendon injuries by developing a method of growing oriented human collagen.

Super microscopes help scientists identify exact molecular 'switch' that spurs T-cells into action

Using the only microscope of its kind in Australia, medical scientists have been able for the first time to see the inner workings of T-cells, the front-line troops that alert our immune system to go on the defensive against germs and other invaders in our bloodstream.

Dendritic cells secrete signal molecule that contributes to pathogenesis of atherosclerosis

Atherosclerosis is the most common cause of cardiovascular disease, and results from chronic inflammation of arterial vessel walls. An international collaboration led by Professor Christian Weber of Ludwig-Maximilians-Universität (LMU) in Munich and Privatdozentin Alma Zernecke of Würzburg University now shows that dendritic cells stimulate this process by derailing a mechanism that normally acts as a brake on immune reactions.

MreB protein molecules assemble into larger units in bacterial cell wall

Almost all bacteria owe their structure to an outer cell wall that interacts closely with the supporting MreB protein inside the cell. As scientists at the Max Planck Institute for Biochemistry and at the French INRA now show, MreB molecules assemble into larger units, but not - as previously believed - into continuous helical structures.

Simple eye scan can detect early signs of diabetes-related nerve damage

Could a simple eye scan detect early signs of diabetes-related nerve damage? Recent research toward developing such a test is the topic of a special article in Optometry and Vision Science, official journal of the American Academy of Optometry.

Scientists invent Monolayer Stress Microscopy to measure physical forces during collective cellular migration

The physical forces that guide how cells migrate-how they manage to get from place to place in a coordinated fashion inside the living body- are poorly understood. Scientists at the Harvard School of Public Health and the Institute for Bioengineering of Catalonia have, for the first time, devised a way to measure these forces during collective cellular migration.

Super-resolution microscopy technique reveals how and why cell's defenses fail against plague

Researchers at Sandia National Laboratories have developed a super-resolution microscopy technique that is answering long-held questions about exactly how and why a cell's defenses fail against some invaders, such as plague, while successfully fending off others like E.coli.

Scientists reveal nerve cells' navigation system

Johns Hopkins scientists have discovered how two closely related proteins guide projections from nerve cells with exquisite accuracy, alternately attracting and repelling these axons as they navigate the most miniscule and frenetic niches of the nervous system to make remarkably precise connections.

Researchers reveal how immune system distinguishes between beneficial and pathogenic organisms

The human gut is filled with 100 trillion symbiotic bacteria-ten times more microbial cells than our own cells-representing close to one thousand different species. "And yet, if you were to eat a piece of chicken with just a few Salmonella, your immune system would mount a potent inflammatory response," says Sarkis K. Mazmanian, assistant professor of biology at the California Institute of Technology (Caltech).
