Abstract
Rheumatoid arthritis (RA) requires therapeutic approaches that alleviate symptoms and inhibit the progression of joint damage. Glucocorticoids (GCs) have been a cornerstone of RA treatment, yet their use is often limited by side effects. Recent advancements suggest that liposome-based delivery systems can improve GC biodistribution, minimizing toxicity. This study introduces an innovative tool for RA treatment using prednisone-encapsulated nonphospholipid liposomes (NPLs) in combination with a hyaluronic acid (HA) hydrogel. Our methodology involved incorporating prednisone (PR) with palmitic acid and cholesterol to formulate stable NPLs using a thin-film hydration technique. The synthesized PR-NPLs, characterized by a mean size of 150 nm, demonstrated uniform distribution and higher drug encapsulation in comparison with conventional phospholipid liposomes. In vitro assays revealed that PR-NPL markedly reduced inflammatory responses in macrophages. Additionally, we successfully incorporated PR-NPL into an HA hydrogel, employing a photoinitiated cross-linking process. This novel composite offered modulable PR release, governed by the degree of hydrogel cross-linking. The developed system presents a promising advancement in RA management, especially suited for intraarticular injections. It potentially enables targeted, controlled drug release with a reduced risk of side effects, signifying a significant improvement over existing RA therapies.
期刊介绍:
Journal of Biomedical Materials Research – Part B: Applied Biomaterials is a highly interdisciplinary peer-reviewed journal serving the needs of biomaterials professionals who design, develop, produce and apply biomaterials and medical devices. It has the common focus of biomaterials applied to the human body and covers all disciplines where medical devices are used. Papers are published on biomaterials related to medical device development and manufacture, degradation in the body, nano- and biomimetic- biomaterials interactions, mechanics of biomaterials, implant retrieval and analysis, tissue-biomaterial surface interactions, wound healing, infection, drug delivery, standards and regulation of devices, animal and pre-clinical studies of biomaterials and medical devices, and tissue-biopolymer-material combination products. Manuscripts are published in one of six formats:
• original research reports
• short research and development reports
• scientific reviews
• current concepts articles
• special reports
• editorials
Journal of Biomedical Materials Research – Part B: Applied Biomaterials is an official journal of the Society for Biomaterials, Japanese Society for Biomaterials, the Australasian Society for Biomaterials, and the Korean Society for Biomaterials. Manuscripts from all countries are invited but must be in English. Authors are not required to be members of the affiliated Societies, but members of these societies are encouraged to submit their work to the journal for consideration.
