Use of raspberry ketone in immune combination therapy for pancreatic cancer

Abstract

The application of raspberry ketone in the immunotherapy of pancreatic cancer belongs to the technical field of biological medicine, and provides the application of raspberry ketone in the immunotherapy of pancreatic cancer. The application discloses that raspberry ketone can specifically and widely up-regulate the expression of MHC-I molecules on the surface of pancreatic cancer cells, and significantly enhances the infiltration and function of anti-tumor effector T cells in the tumor immune microenvironment. In-vivo and in-vitro experiments prove that raspberry ketone can reverse tumor immune escape by up-regulating MHC-I, and after being combined with a PD-1 immune checkpoint inhibitor, the raspberry ketone can produce a significant synergistic anti-tumor effect, significantly inhibit the growth of pancreatic cancer and prolong the survival period of tumor-bearing mice. The application provides a new strategy of combining a natural small molecule immunomodulator with an existing immunotherapy, and provides an innovative solution and a drug candidate for overcoming the difficulty of pancreatic cancer tolerance to immunotherapy.
