Columbia University Researchers Develop Bacteria-Based Trojan Horse System to Deliver Anti-Cancer Viruses

Columbia University researchers have developed an innovative cancer treatment approach that utilizes bacteria as delivery vehicles for anti-cancer viruses, effectively creating a biological Trojan horse system. The engineered bacteria are naturally attracted to cancer cells, allowing them to transport cancer-killing viruses directly into tumors while avoiding detection by the immune system.

The treatment leverages two powerful anti-cancer mechanisms working in tandem. The bacteria serve as targeted delivery vehicles drawn specifically to cancer cells, while the viruses contained within them deliver the final destructive blow to tumor cells once released at the target site. This dual approach represents a significant advancement in precision cancer therapy, potentially overcoming one of the major challenges in oncolytic virus treatments—immune system interception before reaching cancerous tissues.

The field of oncolytic virus research continues to gain momentum, with other organizations like Calidi Biotherapeutics Inc. (NYSE American: CLDI) also making notable progress in similar therapeutic approaches. The convergence of bacterial targeting mechanisms with viral anti-cancer properties creates a synergistic effect that could enhance treatment efficacy while minimizing side effects on healthy tissues.

This research breakthrough has substantial implications for cancer treatment protocols worldwide. By effectively bypassing the immune system's natural defenses against foreign viruses, the treatment could achieve higher concentrations of therapeutic agents within tumors, potentially leading to improved patient outcomes and reduced treatment resistance. The approach represents a paradigm shift in how cancer therapies might be delivered in the future, moving toward more targeted, biologically intelligent systems rather than broad-spectrum treatments.

The development aligns with growing interest in biologically-mediated cancer treatments that work with the body's natural systems rather than against them. As research in this area continues to advance, such approaches could eventually lead to more personalized cancer treatments with fewer side effects and higher success rates. The Columbia University team's work demonstrates the potential of combining different biological mechanisms to create more effective cancer-fighting strategies.
