ethanolic extract (Cm-EE) on sensitizing cancer cells and regulating immune responses against breast cancer (BC) and hepatocellular carcinoma (HCC) cells. Cordycepin, pentostatin and adenosine were identified in Cm-EE. Cordycepin treatment decreased HLA-ABC-positive cells in pre-treated cancer cells, while Cm-EE increased NKG2D ligand and death receptor expression. Additionally, cordycepin enhanced NKG2D receptor and death ligand expression on CD3-negative effector immune cells, particularly on natural killer (NK) cells, while Cm-EE pre-treatment stimulated IL-2, IL-6, and IL-10 production. Co-culturing cancer cells with effector immune cells during cordycepin or Cm-EE incubation resulted in elevated cancer cell death. These findings highlight the potential of cordycepin and Cm-EE in improving the efficacy of cancer immunotherapy for BC and HCC. |
