Understanding the Multicellular Response to Injury in the Mouse Spinal Cord

Weekly Seminar | Not Open to the Public
Who Should Attend: 


Our lab studies the mechanisms of axon regeneration and sprouting after central nervous system (CNS) injury using mouse models of spinal cord injury. We started with the myelin-derived inhibitors and recently shifted focus to neuron-intrinsic pathways such as Pten/mTOR and MAP3Ks. We documented an age-dependent decline in axon regeneration and illustrated a multicellular role for the MAP3K12/13 pathway after CNS injury. Our in vivo imaging data supports a synaptic suppression hypothesis of axon regeneration.
