A tiny enzyme may hold the key to safer pain relief

Researchers have uncovered a surprising way the brain switches pain on, revealing that neurons can release an enzyme outside the cell that activates pain signals without disrupting normal movement or sensation. This enzyme, called VLK, modifies nearby proteins in a way that intensifies pain and strengthens connections tied to learning and memory. Removing VLK in mice dramatically reduced post-surgery pain while leaving normal function untouched, offering a promising path toward safer, more targeted pain treatments.
