CAMBRIDGE, MA— MIT researchers have identified a family of proteins key to the formation of the communication networks critical for normal brain function. Their research could lead to new treatments for brain injury and disease.

The team, led by MIT biology professor Frank Gertler, found that a certain family of proteins is necessary to direct the formation of axons and dendrites, the cellular extensions that facilitate communication between neurons.

Immune system can drive cancers into dormant state
November 19, 2007 08:32 AM - Washington University School of Medicine

A multinational team of researchers has shown for the first time that the immune system can stop the growth of a cancerous tumor without actually killing it.

Scientists have been working for years to use the immune system to eradicate cancers, a technique known as immunotherapy. The new findings prove an alternate to this approach exists: When the cancer can't be killed with immune attacks, it may be possible to find ways to use the immune system to contain it. The results also may help explain why some tumors seem to suddenly stop growing and go into a lasting period of dormancy.
