The potential of resolvin D2 loaded hydroxyapatite/mineral trioxide aggregate electrospun membranes to downregulate Interleukin 1 beta and tumor necrosis factor alpha in human dental pulp stem cells and macrophages co-cultures.
Objective: To develop electrospun polycaprolactone (PCL) membranes incorporating Hydroxyapatite/Mineral Trioxide Aggregate (HAp/MTA) loaded with Resolvin D2 (RvD2) and evaluate its anti-inflammatory potential.
Method: Electrospun membranes were fabricated by blending PCL with 10 wt.% HAp/10 wt.% MTA loaded with or without 0.1% RvD2 and were characterized using Field Emission Scanning Electron Microscopy (FE-SEM), energy-dispersive X-ray (EDX) spectroscopy, Raman spectroscopy, contact angle measurements, and RvD2 release.
Results: The field emission scanning microscopy (FE-SEM) showed uniform nanofibers with an average fiber diameter ranging from 300 to 600 nm. Energy-dispersive X-ray (EDX) analysis and Raman spectroscopy confirmed the presence of HAp and MTA in the PCL membranes. The drug release profile displayed a rapid release of RvD2 initially, followed by a sustained release. XTT assay demonstrated the cytocompatibility of the membranes towards the THP-1-derived M1 macrophages and human dental pulp stem cells (hDPSCs) co-cultures activated with LPS. The FE-SEM studies proved the favorable cell adhesion behaviour although the membranes being hydrophobic. Cytokine levels in the culture supernatants retrieved from the co-culture treated membranes showed that, of all the membranes, RvD2 incorporated PCLHAp/MTA membranes demonstrated reduced IL-1β and TNF-α production.
Conclusions: RvD2 incorporated PCLHAp/MTA membranes demonstrated reduced IL-1β and TNF-α production asserting its anti-inflammotory potential.
Clinical significance: This research highlights the immunomodulatory effect of RvD2-loaded PCLHAp/MTA electrospun membranes in reducing inflammation of the dental pulp. This novel method has the potential to transform the treatment of dental pulp inflammation resulting from caries or injury.
期刊介绍：
The journal Clinical Oral Investigations is a multidisciplinary, international forum for publication of research from all fields of oral medicine. The journal publishes original scientific articles and invited reviews which provide up-to-date results of basic and clinical studies in oral and maxillofacial science and medicine. The aim is to clarify the relevance of new results to modern practice, for an international readership. Coverage includes maxillofacial and oral surgery, prosthetics and restorative dentistry, operative dentistry, endodontics, periodontology, orthodontics, dental materials science, clinical trials, epidemiology, pedodontics, oral implant, preventive dentistiry, oral pathology, oral basic sciences and more.
