Summary: Lumbar intervertebral discs are suspected to be a source of low back pain, in part because of the innervation of these discs by neurons containing substance P and CGRP receptors. Rats received 2.5 µg of 192-IgG-SAP (Cat. #IT-01) into the L5/6 vertebral disc after the disc was punctured. While half of the dorsal root ganglion neurons innervating the disc were positive for CGRP post-puncture, animals receiving 192-IgG-SAP displayed reduced CGRP expression, indicating a role for the p75 receptor in discogenic pain.
