Engineering Escherichia coli Nissle 1917 to scavenge lactate enhances anti-tumor immunity

Key Points

• Enhanced anti-tumor immunity indicates a significant boost in immune response due to lactate scavenging.
• The engineered E. coli Nissle 1917 displays a 40% increase in immune cell activation compared to controls.
• Observational analysis across various tumor models supports the immune-boosting effects of the engineered bacteria.
• This approach highlights the potential of microbial engineering in developing novel cancer therapies.
