Natural process activating brain's immune cells could point way to repairing damaged brain tissue

Posted: 21 Oct 2012 10:39 AM PDT

The brain's key "breeder" cells, it turns out, do more than that. They secrete substances that boost the numbers and strength of critical brain-based immune cells believed to play a vital role in brain health. This finding adds a new dimension to our understanding of how resident stem cells and stem cell transplants may improve brain function.

Discovery of biological energy-sensing switch could have broad implications for biology and medicine

Posted: 21 Oct 2012 10:39 AM PDT

Biochemists have discovered a genetic sequence that can alter its host gene's activity in response to cellular energy levels. The scientists have found this particular energy-sensing switch in bacterial genes, which could make it a target for a powerful new class of antibiotics. If similar energy-sensing switches are also identified for human genes, they may be useful for treating metabolism-related disorders such as type 2 diabetes and heart disease.
