ABSTRACT
Objective To explore the role of hMSH2, a novel endogenous tumor-associated pro-tein ligand recognized by Vγ9δ2 T cells, in innate anti-cervix cancer immunity .Methods hMSH2 that ex-pressed on the surface of cervical cancer cell line HeLa cells was blocked by specific antibody .Then the differences in their effects on Vγ9δ2 T cells before and after antibody blockage were evaluated by cytotoxicity of Vγ9δ2 T cells and cytokines secretion .The serum levels of hMSH2 in patients with cervical cancer were detected by ELISA .Distribution of hMSH2 in cervical cancer tissues was analyzed by TMA immunohisto-chemistry .Results Decreased cytotoxicity and IFN-γsecretion were observed in Vγ9δ2 T cells against He-La cells blocked with specific anti-hMSH2 antibody .Serum concentration of hMSH 2 in patients with cervical cancer was slightly higher than that of healthy control .Altered distribution pattern of hMSH 2 was observed in cervical cancer tissues .Conclusion hMSH2 is involved in Vγ9δ2 T cells-mediated innate anti-cervical cancer immunity by enhancing their cytotoxicity and IFN-γsecretion.
