Developing new drug delivery systems is crucial for enhancing the efficacy of oncolytic virus (OV) therapies in cancer treatment. In this study, mesenchymal stem cell (MSC)-derived vesicles and viruses are exploited to construct a novel formulation. It has been hypothesized that vesicle-coated OVs could amplify cytotoxic effects through superior internalization by tumor cells. MSC possess natural homing ability biocompatibility, which can enhance targeting, uptake, therapeutic on Experimental results indicated treatment system increased apoptosis Furthermore, flow cytometry analysis demonstrated uptake cells coated with soared away compared uncoated OVs, being 1.5 times than group.

Malignant gliomas present great difficulties in treatment, with little change over the past 30 years median survival time of 15 months. Current treatment options include surgery, radiotherapy (RT), and chemotherapy. New therapies aimed at suppressing formation new vasculature (antiangiogenic treatments) or destroying formed tumor (vascular disrupting agents) show promise. This study summarizes existing knowledge regarding processes by which glioblastoma (GBM) tumors acquire resistance to antiangiogenic treatments. The discussion encompasses activation redundant proangiogenic pathways, heightened cell invasion metastasis, induced hypoxia, creation vascular mimicry channels, regulation immune microenvironment. Subsequently, we explore potential strategies overcome this resistance, such as combining other methods, personalizing treatments for each patient, focusing on therapeutic targets, incorporating immunotherapy, utilizing drug delivery systems based nanoparticles.

Until now, there has been a lack of effective strategies for cancer treatment. Immunotherapy high potential in treating several cancers but its efficacy is limited as monotherapy. Chemoimmunotherapy (CIT) holds promise to be widely used Therefore, identifying their involvement and synergy CIT approaches decisive. Nano-based drug delivery systems (NDDSs) are ideal because they can simultaneously target immune cells cells, promoting accumulation, reducing the toxicity drug. In this review, we first introduce five current immunotherapies, including checkpoint blocking (ICB), adoptive cell transfer therapy (ACT), vaccines, oncolytic virus (OVT) cytokine therapy. Subsequently, immunomodulatory effects chemotherapy by inducing immunogenic death (ICD), tumor killer infiltration, down-regulating immunosuppressive inhibiting checkpoints have described. Finally, NDDSs-mediated collaborative introduced detail, development nanoparticles prospected.
