PV-Mediated Drug Delivery for Tumor Immunotherapy

-The application of PV-based delivery systems in tumor immunotherapy

PV systems are known to be capable of content material delivery to specific host cells through their only round of replication. Therefore, when packaged with 'suicide genes' dictating for tumor cell death, it becomes a powerful weapon against malignancies that could be difficult for conventional drug administration, for example cancers in mucosal tissues. The efficacy of PV-based suicide gene delivery has been demonstrated by research on treatment of bladder cancer. In this application, artificially assembled PVs act as delivery vectors transferring suicide genes to the internal of tumor cells. Successful induction of tumor cell death (TCD) and further adaptive immune response against NIMBC has been achieved on immunotherapy using PV vectors packaged in Human Papillomavirus (HPV) capsids.

-The advantage of PV-mediated systems to conventional approaches?

  1. Capability to effectively deliver therapeutic entities to sites otherwise challenging to reach;
  2. High PV titer;
  3. Capability to induce adaptive immune response against cancer, reducing the risk for recurrence.
