Scientists turn food poisoning microbe into powerful cancer fighter

Researchers have found a protein that can stimulate an immune cell response. They have taken S. Typhimurium and modify to secrete FlaB protein. An animal study in mice looking at the cancerous tumor cells, when injected with the modified bacteria, it was cleared from the mice body within 3 days. The cancerous cells were still present, but after 4 months 50% of the mice had no detectable tumor. When the researchers used mice infected with cancer, S. Typhimurium was able to reduced or eliminated the metastasis cancerous cells. Genetically modifying bacteria for medical purposes is a very interesting topic. Hopefully, this animal trial gets to move onto the next clinical trials. It can save many lives if the human body can now detect invaders and activate an immune response to the cancer cells.
