Episode notes
Combining Modalities Solves Delivery Limits
- Bacteria preferentially colonize hypoxic tumor cores while oncolytic viruses kill cancer cells and can spread to metastases.
- Combining them addresses delivery and immune‑clearance limits of each modality alone.
Tumor‑Triggered Viral Expression And Self‑Replication
- The team used tumor‑specific promoters so viral genes express only after bacteria reach the tumor microenvironment.
- They added a T7 RNA polymerase so viruses replicate independently of dysfunctional cancer machinery.
Mouse Trial Cleared Tumors Systemically
- In mouse models with tumors in both flanks, injecting the therapy into one tumor cleared both sites and yielded 100% survival.
- The local bacterial delivery created systemic viral spread that attacked distant cancer sites.
