Abstract
In the present work curcumin loaded hyalurosomes were proposed as innovative systems for the treatment of rheumatoid arthritis. Vesicles were prepared using a one-step and environmentally friendly method. Aiming at finding the most suitable formulation in terms of size, surface charge and stability on storage, an extensive pre-formulation study was performed using different type and amount of phospholipids. Curcumin loaded vesicles prepared with 180 mg/ml of Phospholipon 90G (P90G) and immobilized with sodium hyaluronate (2 mg/ml) were selected because of their small size (189 nm), homogeneous dispersion (PI 0.24), negative charge (−35 mV), suitable ability to incorporate high amount of curcumin (E% ∼88%) and great stability on storage. The in vitro study using fibroblast-like synovial cells cultured in synovial fluid, demonstrated the ability of these vesicles to downregulate the production of anti-apoptotic proteins IAP1 and IAP2 and stimulate the production of IL-10, while the production of IL-6 and IL-15 and reactive oxygen species was reduced, confirming their suitability in counteracting pathogenesis of rheumatoid arthritis.File | Dimensione | Formato | |
