Mechanisms of Axon Regeneration

Research in the Cavalli Lab is focused on understanding the signals that a neuron receives when its axon is injured and how this leads to regeneration, in the case of the peripheral nervous system but not in the central nervous system. This has led to two main research areas:

1) What are the molecules and molecular tracks that relay an injury signal from an axon to the nucleus? 2) How is a pro-regenerative signaling cascade initiated in the nucleus once an injury signal is received?

Ultimately, Dr. Cavalli hopes to uncover the means by which peripheral nerves regenerate and apply this knowledge to treatments for central nervous system injuries and diseases.
