Joslin scientists show knocking out two key signals will cause diabetes
Using a revolutionary technique to turn off chemical signals inside the cell, scientists at Joslin Diabetes Center have discovered that the different metabolic abnormalities present in type 2 diabetes can be caused by knocking out two key signals in liver cells. Their findings in mice may someday lead to strategies in humans to boost these two different signals, providing a powerful new way to treat the different metabolic components present in the most common form of diabetes.  more

Research identifies proteins crucial to construction of brainís information superhighway
Communication in the brain travels from one nerve cell to another through critical connections called synapses. These neuron-to-neuron junctions form early in brain development, and their construction was thought to be guided by the nerve cells themselves. Now, investigators supported by the National Institute on Drug Abuse (NIDA), National Institutes of Health, have discovered that cells called glia, known to provide support for neurons in the mature brain, also play a crucial role in formation of synapses during the surge of development following birth.  more
