Researchers identify osteoarthritis ‘pain pathway’

Researchers have discovered that a particular molecular signaling pathway plays an important role in producing osteoarthritis (OA) pain. Using a mouse model of painful osteoarthritis, they show that blocking this signaling pathway eliminates pain and results in a return to normal limb use. This work is the first to find an association between this pathway and OA pain, and could lead to the development of new, effective pain treatments for human OA sufferers.
