| Research Abstract |
We evaluated the role of integrin-αvβ3 on the regulation of prognosis and therapeutic response of malignant melanoma. The melanoma cells that acquire the resistance to anticancer drugs displayed a significant upregulation of integrin-αvβ3. The integrin-αvβ3 on the chemoresistant melanoma manipulates dendritic cells to induce tolerogenic activities, thereby impairing antitumor immune responses. These findings verified novel molecular machineries whereby tumor resistance to anticancer therapeutics is associated with impairment of host antitumor immunity.
