Polydopamine-Coated Poly(l-lactide) Nanofibers with Controlled Release of IL-10 for Effective Management of Peripheral and Central Neuropathic Pain in Rats.

ABSTRACT: Managing neuropathic pain is challenging due to the complex pathogenetic mechanisms and limited available drugs and therapeutic options. Innovative nanofiber systems offer a novel method to effectively administer therapeutic cytokines, drugs, or small molecule compounds to achieve better relief of neuropathic pain. Here, we report a novel nanofiber with controlled release of IL-10 for implantation into ligated nerve roots and hemisection-injured spinal cords to exert anti-inflammatory effects and attenuate neuropathic pain. An electrospun poly(l-lactide) (PLLA) nanofiber was modified by a polydopamine (PDA) coating, and this nanofiber demonstrated sustained release of IL-10 in vitro. We showed that L5 spinal nerve ligation and T13 spinal cord hemisection induced peripheral and below-level
