Join us for this lecture where Professor Zach Murphy explains the processes of nerve injury and repair, focusing on Wallerian degeneration and the mechanisms of axonal regeneration. We begin by examining the events that occur distal to the site of nerve injury, including axonal breakdown, myelin clearance by Schwann cells and macrophages, and the preservation of the connective tissue scaffolding necessary for potential regrowth. We then move into the cellular and molecular responses that occur proximally, covering chromatolysis within the neuronal cell body and the upregulation of proteins essential for axonal repair. The discussion highlights the critical role of Schwann cells in forming bands of Büngner to guide regenerating axons, the influence of neurotrophic factors, and the differences in regenerative capacity between the peripheral and central nervous systems. Finally, we tie these processes into functional recovery, explaining factors that influence repair success, such as the distance to the target organ, the extent of injury, and time since injury. This provides a comprehensive understanding of how peripheral nerves can restore function after damage, and why regeneration is often limited in the CNS.
