简介:
Overview
This article details the partial sciatic nerve ligation (PSNL) procedure, a widely used mouse model for studying chronic neuropathic pain. The model effectively mimics human neuropathic pain symptoms, making it essential for developing new pain management therapies.
Key Study Components

What is partial sciatic nerve ligation?
Partial sciatic nerve ligation (PSNL) is a surgical procedure used to induce chronic neuropathic pain in animal models.
Why is PSNL important for pain research?
PSNL mimics human neuropathic pain symptoms, making it essential for studying pain mechanisms and testing new therapies.
How does the Von Frey test work?
The Von Frey test assesses pain sensitivity by applying calibrated filaments to the paw and measuring withdrawal responses.
What are the expected outcomes of using PSNL?
Expected outcomes include long-lasting pain responses and heightened sensitivity to stimuli in the affected mice.
How can this protocol improve pain management research?
Standardizing the PSNL procedure enhances reproducibility and reliability in pain management studies.
Who demonstrated the PSNL procedure in this article?
The procedure was demonstrated by Kevin Cheng, an MD PhD candidate.
