Researchers Uncover Key Step In Manufacture of Memory Protein

...until they are ready to be secreted. Once the cell receives an electrical signal from another neuron, these vesicles fuse with the cell’s outer membrane, open up, and release mBDNF. During their research, Dr. Loh and her colleagues observed mice genetically incapable of producing CPE. In these mice, proBDNF ...

A probe, not an echo

... A parallel array of transducers on the other side receives the pulses after they travel through the imaged tissue. A sophisticated coding/decoding signal scheme recognizes a small "sweet spot" of the signal coming from the opposite transducer, and only that transducer, and ignores all other pulses transmitt...

Researchers discover mechanism for multiplying adult stem cells
