Combination of anti-inflammatory therapy and RNA interference by light-inducible hybrid nanomedicine for osteoarthritis treatment.

ABSTRACT: Osteoarthritis (OA) is a type of highly prevalent heterogeneous degenerative disease that leads to joint pain, deformity, the destruction of articular cartilage, and eventual disability. The current treatment strategies for OA often suffer from systemic side effects, poor anti-inflammatory efficacy, and persistent pain. To address these issues, we develop light-inducible nanomedicine that enables the co-delivery of anti-inflammatory drug (diacerein, DIA) and small interfering RNA (siRNA) targeting nerve growth factor (NGF) for pain relief to enhance the therapeutic efficacy of OA. The nanomedicine is based on poly(β-amino-ester)-coated gold nanocages (AuNCs), which is further incorporated with the phase-change material (lauric acid/stearic acid, LA/SA). Following intra-articular (IA
