Researchers develop mutant gene-targeted immunotherapy approach to fight cancers A novel targeted immunotherapy approach developed by researchers at the Ludwig Center, the Lustgarten Laboratory, and Bloomberg~Kimmel Institute for Cancer Immunotherapy at the Johns Hopkins Kimmel Cancer Center employs new antibodies against genetically altered proteins to target cancers. The researchers targeted their immunotherapy approach to alterations in the common cancer-related p53 tumor suppressor gene, the RAS tumor-promoting oncogene or T-cell receptor genes. They also tested the therapy on cancer cell...

Two of the three research studies -- led by Jacqueline Douglass, M.D., Ph.D. candidate at the Johns Hopkins University School of Medicine and Emily Han-Chung Hsiue, M.D., Ph.D., postdoctoral fellow at Johns Hopkins--report on a precision medicine immunotherapy approach that specifically kills cancer cells by targeting mutant protein fragments presented as antigens on the cancer cell surface. Although common across cancer types, p53 mutations have not been successfully targeted with drugs. Genetic alterations in tumor suppressor genes often resulted in their functional inactivation. "Tradition...
