Scientists Turn Bacteria into Trojan Horses to Deliver Anti-Cancer Viruses into Tumors
Scientists at Columbia University have engineered a cancer treatment that leverages bacteria to smuggle cancer-killing viruses into tumors in a method that sidesteps the defenses of the immune system. This groundbreaking approach utilizes two vital weapons against the cancer; the bacteria are drawn to cancer cells, and the viruses inside the bacteria deliver the killer blow to the tumor cells after being delivered there by the bacteria. The study team was successful in creating built-in safeguards intended to prevent the viruses from infiltrating and infecting tissues outside the tumor environment. Their research promises to introduce a new paradigm in the…
