B1 and TRPV-1 Receptor Genes and Their Relationship to Hyperalgesia Following Spinal Cord Injury

Abstract

B1 and TRPV-1 receptor genes are overexpressed in the injured spinal cord of animals manifesting thermal hyperalgesia following SCI compared with similarly injured animals without hyperalgesia. This finding is consistent with past work regarding the role of these receptors in nociception and indicates that ongoing modifiable processes are occurring in the spinal cord that lead to clinical pain syndromes.
