Nerve Ligation

Nerve ligation is a surgical procedure that ties off, compresses, or occludes a nerve to interrupt its normal signaling and study the consequences of peripheral nerve injury. By applying a controlled ligature, researchers disrupt axonal transport and local nerve function, triggering injury-related cellular responses that can produce altered sensory processing and neuropathic pain. In neuroscience, nerve ligation models help investigate pain pathways, neuroinflammation, neuronal sensitization, and nerve repair. These models also support evaluation of analgesic treatments and provide insight into how peripheral injury changes communication between nerves, the spinal cord, and the brain.

In molecular biology, ligation refers to the joining of two DNA fragments through the formation of a phosphodiester bond. An enzyme known as a ligase catalyzes the ligation reaction. In the cell, ligases repair single and double strand breaks that occur during DNA replication. In the laboratory, DNA ligase is used during molecular cloning to join DNA fragments of inserts with vectors – carrier DNA molecules that will replicate target fragments in host organisms. This video provides an...
