Abstract

Rheumatoid arthritis (RA) is a kind of systemic autoimmune disease, and patients with RA usually suffer serious pain, resulting in low quality of life. The development of drug delivery systems (DDSs) provides a valid approach for RA therapy via inhibiting the secretion of inflammatory cytokines from macrophages. As a prevailing drug nanocarrier with distinctive superiority, polymeric nanoparticles (NPs) have attracted much attention in recent years. However, low biocompatibility and limited exploitation of drug with high efficiency are still the main challenges in RA treatment. To overcome the limitations, we prepared a biocompatible copolymer methoxy-poly(ethylene glycol)-poly(lactide-co-glycolide) (mPEG-PLGA). Moreover, benzoylaconitine (BAC) with superior anti-inflammatory effect was selected as model drug. It was isolated from Aconitum kusnezoffii Reichb and encapsulated into mPEG-PLGA NPs (NP/BAC) to increase the bioavailablity of BAC. The NPs exhibited high cytocompatibility for activated macrophages and well compatibility with red blood cells. Furthermore, the anti-inflammatory property of NP/BAC was testified by substantially inhibiting secretion of pro-inflammatory cytokines. The TNF-α and IL-1β cytokines of NP/BAC group reduced 70 % and 66 % compared with that of activated macrophages. Especially, NP/BAC reduced the overexpression of NF-κB p65 to inhibit NF-κB signaling pathway, which was a critical regulator of inflammatory responses. NP/BAC also showed efficient in vivo anti-inflammatory effect with high ear (69.8 %) and paw (87.1 %) swelling suppressing rate. These results revealed the anti-inflammatory mechanism of NP/BAC and proved it was a suitable DDS to suppress inflammation, providing a promising strategy for RA therapy and research of Aconitum kusnezoffii Reichb.
