Tumor-targeting Salmonella expressing apoptosis-inducing cytotoxic proteins

Tumor-targeting bacteria offer a number of advantages over other cancer drug delivery systems, including targeting of multiple tumors from a distant inoculation site, selective intratumoral replication, a high degree of attenuation and safety, and the ability to express anti-cancer proteins directly within the tumor. Remarkably, attenuated Salmonella localize within solid tumors at levels at least 1000 times greater than...
