TL;DR
Researchers developed a nano-drug delivery system using cancer cell membranes and traditional Chinese medicine to treat lymphoma more effectively with reduced toxicity.
Contribution
A novel pH-sensitive drug delivery system using cancer cell membrane-camouflaged nanoparticles loaded with traditional Chinese medicine for lymphoma treatment.
Findings
The nano-platform CCM@MSNs-ISOIM exhibits immune escape and anti-phagocytosis properties.
It effectively targets tumor cells, blocks the cell cycle, and promotes apoptosis in lymphoma cells.
The system shows high drug loading, biocompatibility, and low systemic toxicity.
Abstract
Non-Hodgkin’s lymphoma (NHL) possesses great heterogeneity in cytogenetics, immunophenotype and clinical features, and chemotherapy currently serves as the main treatment modality. Although employing monoclonal antibody targeted drugs has significantly improved its overall efficacy, various patients continue to suffer from drug resistance or recurrence. Chinese medicine has long been used in the treatment of malignant tumors. Therefore, we constructed a low pH value sensitivity drug delivery system based on the cancer cell membrane modified mesoporous silica nanoparticles loaded with traditional Chinese medicine, which can reduce systemic toxicity and improve the therapeutic effect for the targeted drug delivery of tumor cells. Accordingly, this study put forward the construction of a nano-platform based on mesoporous silica nanoparticles (MSNs) loaded with the traditional Chinese…
