Compositions and Methods for Inhibiting an Oncogenic Protein to Enhance Immunogenicity

摘要

The present invention includes compositions and methods for inhibiting an oncogenic protein or its down-stream effector protein to suppress expression of a cell-surface protein involved in inhibiting immune response against malignant cells thereby enhancing immunogenicity of a cell. The invention includes inhibitors of expression of CD274 and/or its functional cell-membrane bound immunosuppressive analog. The invention includes inhibitors of function or expression of oncogenic ALK tyrosine kinase and/or other oncogenic proteins responsible for induction of expression of CD274 or its functional immunosuppressive equivalent. The invention includes inhibitors of function or expression of STAT3 and/or other cell signal transmitters and/or transcription factors activated by ALK or its functional analog involved in induction of expression of CD274 or its functional analog.
