Research interests
The low regenerative capacity of mature neurons in the adult central nervous system (CNS) represents a significant barrier to recovery following spinal cord injury. The aim of my PhD project is to use integrins to enhance the regeneration of CNS neurons in the context of spinal cord injury. Integrins are transmembrane receptors that bind to ligands that are present in the extracellular matrix. Ligand binding triggers intracellular signalling cascades that can influence cellular migration and growth. The forced expression of certain integrins in adult mouse CNS neurons can enhance axonal regeneration after spinal cord injury.
Unfortunately, integrins are excluded from the axon of mature neurons in the CNS limiting their proregenerative effect. I am investigating novel techniques to overcome their exclusion from the axon in adult neurons in the CNS. These techniques include modifying integrins to enhance their trafficking into the axon and using exosomes to deliver integrins directly to the axon.
