Enhancing cancer immunotherapy using cordycepin and Cordyceps militaris extract to sensitize cancer cells and modulate immune responses.

ABSTRACT: Integrating immunotherapy with natural compounds holds promise in enhancing the immune system's ability to eliminate cancer cells. Cordyceps militaris, a traditional Chinese medicine, emerges as a promising candidate in this regard. This study investigates the effects of cordycepin and C. militaris 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
