Bacteria Used to Destroy Cancer Tumors in Mice The study was published in the journal Nature Medicine. Scientists genetically reprogrammed bacteria to create "nanobodies." Nanobodies can be thought of as small, more potent versions of antibodies. Antibodies attach to proteins on cancer cells to help the immune system recognize the cells as dangerous. Bacteria use cancer cells to colonize and as protection from the human immune system. The modified bacteria were injected into tumors, and then began to multiply and produce the tumor fighting nanobodies. The bacteria also "uncloaked" the cancer cells, engaging the immune system in the fight against the tumors. If the method works in humans, scientists are hopeful that it could treat cancer "more precisely" without harmful drug side effects.
