Antibody Appears to Attack Cancer Cells, Leaving Other Cells Unscathed (image) Duke University Medical Center Share Print E-Mail Caption A research team from Duke Health has developed an antibody from the body's own immune system that preferentially attacks cancer cells. The antibody works by targeting a natural defense mechanism that cancer tumors exploit. Cells in the body essentially use a home security system that relies on certain proteins to protect the cell surface and keep it safe. These proteins help the cell avoid injury and even death from unwanted activation of the immune system.
