Lawrence Berkeley National Laboratory Your cells are social butterflies. They constantly interact with their surroundings, taking in cues on when to divide and where to anchor themselves, among other critical tasks. This networking is driven in part by proteins called integrin, which reside in a cell´s outer plasma membrane. Their job is to convert mechanical forces from outside the cell into internal chemical signals that tell the cell what to do. That is, when they work properly....

A team including scientists from The Scripps Research Institute (TSRI), the University of North Carolina at Chapel Hill and the Chinese Academy of Sciences has determined and analyzed the high-resolution atomic structures of two kinds of human serotonin receptor. The new findings help explain why some drugs that interact with these receptors have had unexpectedly complex and sometimes harmful effects. "Understanding the structure-function of these receptors allows us to discover new...

Some 5.8 million Americans suffer from heart failure, a currently incurable disease. But scientists at Temple University School of Medicine's (TUSM) Center for Translational Medicine have discovered a key biochemical step underlying the condition that could aid the development of new drugs to treat and possibly prevent it. "Drugs we currently use for heart failure are not very effective," explained lead investigator Walter J. Koch, PhD, Professor and Chairman of the Department of...

Lee Rannals for redOrbit.com — Your Universe Online One new method may be able to lead to more effective medications, with fewer side effects, according to research published in the Journal of Neuroscience. Scientists from the University of Texas Medical Branch (UTMB) at Galveston and the University of Houston found a new way to influence the vital serotonin signaling system. The team linked malfunctions in serotonin signaling to a range of health issues, including everything from...

New Study Advances Leading-Edge Field of Optogenetics at Rensselaer Polytechnic Institute and UC Berkeley A new study from engineers at Rensselaer Polytechnic Institute and the University of California, Berkeley, pairs light and genetics to give researchers a powerful new tool for manipulating cells. Results of the study, published in the journal Nature Methods, show how blue light can be used as a switch to prompt targeted proteins to accumulate into large clusters. This process of...
