Bioengineered smart bacterial carriers for combinational targeted therapy of solid tumours

Area of Science:

• Oncology
• Biotechnology
• Microbiology

Background:

• Current cancer chemotherapies face limitations including lack of specificity and drug resistance.
• Solid tumor treatment remains a significant challenge in oncology.
• There is a need for targeted anticancer agents with improved efficacy and reduced side effects.

Purpose of the Study:

• To explore the potential of bioengineered bacteria as targeted drug delivery systems for cancer therapy.
• To provide comprehensive insights into bacteria-based cancer therapies (BCTs).
• To discuss the application of engineered bacteria in diagnosing and treating cancer.

Main Methods:

• Review of existing literature on bacteria-based cancer therapies.
• Analysis of the mechanisms by which bacteria target the tumor microenvironment (TME).
• Discussion of engineering strategies for bacteria as therapeutic carriers.

Main Results:

• Bioengineered bacteria can selectively target the TME, proliferating in anaerobic and necrotic regions.
• Bacteria can be engineered as smart microrobots for controlled therapeutic agent delivery.
• BCTs show potential for both diagnosis and treatment of cancers.

Conclusions:

• Bioengineered bacteria represent a promising strategy for smart, targeted cancer therapy.
• BCTs can overcome key limitations of conventional chemotherapy.
• Further research into engineered bacteria holds significant potential for advancing cancer treatment.
