Description of Itmat Expertise

The ultimate goal of Dr. Zhang’s research is to develop non-operative treatments for intervertebral disc degeneration and related back pain.

In order to better understand the mechanism of intervertebral disc degeneration and discogenic back pain, tissues from cadaveric donors and patients undergoing spinal surgery were collected and molecular markers such as chemokines (e.g., IL-8) and matrix-degrading enzymes (e.g., ADAM-8) have been examined. Future studies include dissecting the upstream regulators and downstream effectors of these molecules in cultured disc cells and in genetically modified mice.
