US scientists have developed a novel cancer therapy based on a "Trojan horse" concept, where bacteria and viruses collaborate to precisely target and destroy cancer cells. The ingenuity of this technology lies in hiding oncolytic viruses within bacteria that can automatically seek out tumors, allowing them to evade the human immune system. Once inside the tumor, the bacteria release an army of viruses to launch a deadly attack on cancer cells.

This approach addresses the core challenge of oncolytic virus therapy: the human immune system. Previously, antibodies in a patient’s body who had encountered a specific virus would neutralize it, preventing it from reaching the tumor. Professor Tal Danino’s team utilizes bacteria as an "invisibility cloak" to safely "smuggle" viruses to their destination. This system, named CAPPSID, was developed by a team at Columbia Engineering, with findings published in the journal "Nature Biomedical Engineering."

The key breakthrough of this technology is the bacteria's ability to act as a delivery vehicle for viruses, bypassing the immune response that would otherwise hinder the therapy's efficacy. The bacteria leverage the tumor’s hypoxic and nutrient-rich environment to multiply and release viruses. The viruses then exploit their natural tendency to infect and kill cancer cells, subsequently spreading throughout the tumor. To prevent uncontrolled viral spread to healthy tissues, the team designed a "molecular insurance" to ensure the viruses do not proliferate outside the tumor.
