Nerve Cells In The Brain And Spinal Cord Sense Pain Caused By Physical Insult

Researchers have shown that the protein COX2 in mouse nerve cells in the central

nervous system (CNS) is crucial for hypersensitivity to pain caused by the

physical insult associated with inflammation, but not pain caused by the heat

associated with inflammation. As pain caused by physical insult is a major

symptom of postoperative and arthritic inflammation, it seems that COX2 in nerve

cells in the CNS is central to the pain that accompanies these conditions.
