<scp>CC</scp>‐chemokine ligand 4/macrophage inflammatory protein‐1β participates in the induction of neuropathic pain after peripheral nerve injury

These results suggest that MIP-1β is a novel key mediator, and the peripheral MIP-1β-CCR5 axis contributes to neuropathic pain. Therefore, investigation of this cascade might be a validated approach for the elucidation of neuropathic pain mechanisms.
