Engineered bacteria show promise in cancer therapies

Scientists are reviving bacteria-based cancer therapies, which date back to the 1860s, by using genetically engineered bacteria to target and destroy cancer cells. This approach had been overshadowed by traditional treatments but is gaining renewed interest due to advances in immunology. Recent developments in synthetic biology allow researchers to program bacteria to deliver anti-cancer agents directly to tumors. This targeted method may reduce side effects and improve treatment for solid tumors, particularly those resistant to conventional therapies. Encouraging results from studies show engineered bacteria can help train the immune system to recognize and attack cancer cells. While still in early stages, these therapies could offer new hope for effective cancer treatment as understanding of tumor biology and bacterial engineering improves.
