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...

A new study has exam­ined how bac­te­ria clog med­ical devices, and the result isn´t pretty. The microbes join to cre­ate slimy rib­bons that tan­gle and trap other pass­ing bac­te­ria, cre­at­ing a full block­age in a star­tlingly short period of time. The find­ing could help shape strate­gies for pre­vent­ing clog­ging of devices such as stents – which are implanted in the body to keep open blood...

A new way of looking at a cell's surface reveals the distribution of small molecules in the cell membrane, changing the understanding of its organization. A novel imaging study by researchers from Lawrence Livermore National Laboratory, the University of Illinois and the National Institutes of Health revealed some unexpected relationships among molecules within cell membranes. Their findings provide a new way of studying cell structure and ultimately its function. Led by Mary Kraft...
