Natural product-integrated microneedle patch for rheumatoid arthritis treatment through anti-inflammation and angiogenesis suppression

Abstract

simultaneously promoting M2 macrophage polarization and anti-angiogenesis effect by decreasing the endothelial cell migration and tube formation. The combined Ber and Sin further amplified these effects. The therapeutic microneedle patch (B/S-TM@MN) significantly decreased the expression of CD68-positive macrophages and CD31-stained blood vessel, attaining improved anti-arthritis efficacy compared with monotherapies in the collagen-induced arthritis (CIA) mouse model. Our work represents a promising strategy for targeting multiple pathological factors for enhanced anti-RA therapy.
