Breast Cancer Survivor May Develop a Vaccine for the Disease

Dr. Yvonne Paterson's vaccine Lovaxin B now in pre-clinical testing. A vaccine for breast cancer may be developed through the leadership of a breast cancer survivor. Yvonne Paterson, Ph.D., the scientific founder of Advaxis, Inc., as well as a Professor of Microbiology at the University of Pennsylvania, and her team, are working on a suite of new vaccines to treat women with different types of cancers, including breast cancer. Central to the team's discovery is the microbe Listeria monocytogenes, a bacterium found in dairy products. Dr. Paterson built upon the well-known fact that when Listeria is introduced into the body, it has an extremely powerful, direct stimulatory effect on the activities of immune killer T cells. By modifying Listeria to deliver cancer antigens, Dr. Paterson was able to direct this response to kill cancer cells. These modified-Listeria vaccines harness the power of the immune system to mount an attack against the Listeria and at the same time, redirect the immune system to also attack the cancer cells. --Click the title of this post to read the full article from its source--
