Finding New Ways That Our Immune System Can Help Us Beat Cancer

A newly-discovered part of our immune system could be harnessed to treat all cancers, say scientists. Scientist discovered a method of killing prostate, breast, lung and other cancers in lab tests. Our immune system is our body’s natural defense against infection, but it also attacks cancerous cells. What they found was a T-cell inside people’s blood. This is an immune cell that can scan the body to assess whether there is a threat that needs to be eliminated.T-cells have “receptors” on their surface that allow them to “see” at a chemical level. T-cell and its receptor that could find and kill a wide range of cancerous cells in the lab including lung, skin, blood, colon, breast, bone, prostate, ovarian, kidney and cervical cancer cells. Crucially, it left normal tissues untouched. The idea is that a blood sample would be taken from a cancer patient. Their T-cells would be extracted and then genetically modified so they were reprogrammed to make the cancer-finding receptor.
