Abstract
Glioma remains a significant global health challenge, and is characterized by a persistently high mortality rate. Chemotherapy is a common treatment for glioma, but many anticancer drugs exhibit poor permeability across the blood-brain barrier (BBB) and fail to reach tumor tissues adequately, while also exerting toxic effects on normal cells. To address these issues, this study investigated the use of niosomes (Nio), which are biocompatible, biodegradable, and non-immunogenic, to encapsulate curcumin (Cur) and enhance its delivery to glioma tissues. Niosomes were prepared using the non-ionic surfactant sorbitan monostearate (Span 60) and cholesterol as carrier materials, and subsequently modified with transferrin (TF) to facilitate receptor-mediated transport across the BBB. The resulting TF-modified curcumin niosomes (TF-Cur-Nio) demonstrated enhanced targeting of brain tumors, improved anti-glioma efficacy, and favorable in vivo safety. These findings suggest that the TF-Cur-Nio delivery system has significant potential for advancing glioma treatment by overcoming the limitations of conventional chemotherapy and improving drug delivery to the brain.
Overview
- The study investigates the use of niosomes to encapsulate curcumin and enhance its delivery to glioma tissues to overcome chemotherapy limitations.
- Niosomes were prepared using sorbitan monostearate and cholesterol as carrier materials, and modified with transferrin to facilitate receptor-mediated transport across the blood-brain barrier.
- The study aims to develop a novel delivery system to improve anti-glioma efficacy and safety by targeting brain tumors.
Comparative Analysis & Findings
- The TF-Cur-Nio delivery system demonstrated enhanced targeting of brain tumors compared to unmodified curcumin.
- TF-Cur-Nio showed improved anti-glioma efficacy and favorable in vivo safety compared to conventional chemotherapy.
- The study suggests that the TF-Cur-Nio delivery system has significant potential for advancing glioma treatment by overcoming the limitations of conventional chemotherapy.
Implications and Future Directions
- The study implies that the TF-Cur-Nio delivery system can improve treatment outcomes for glioma patients by enhancing delivery of curcumin to brain tumors.
- Future studies could explore the use of TF-Cur-Nio in combination with other anticancer agents to further enhance treatment efficacy.
- Additionally, the study suggests that the TF-Cur-Nio delivery system could be used to target other brain tumors or cancers with high BBB permeability barriers.
