Overview

Review demonstrates engineered bacterial platforms delivering targeted therapeutics to hypoxic tumors, highlighting their potential as programmable living drug factories.

Key Points

To review the dual roles of tumor-associated microbiota and summarize advances in engineering programmable bacteria for targeted cancer immunotherapy and drug delivery.
Synthesized findings across synthetic biology, nano-biohybrid engineering, and tumor immunology regarding bacterial cancer therapies.
Evaluated mechanisms of bacterial homing to hypoxic tumor cores and localized release of cytotoxic agents, enzymes, and immunomodulators.
Assessed clinical trial pipelines alongside critical hurdles in biosafety, biocontainment, and manufacturing scalability.
Engineered bacteria exploit innate tropism for hypoxic tumor cores to selectively deliver therapeutic payloads while minimizing off-target toxicity.
Bacterial components, including outer membrane vesicles and spores, effectively remodel immunosuppressive tumor microenvironments and enhance immune checkpoint therapies.
Clinical translation requires overcoming core engineering challenges regarding biocontainment, living drug stability, and scalable manufacturing.
