ABSTRACT
Objective To investigate the expression of PD‐L1 in the CD4+CD25hiCD127low/‐ Treg cells in the peripheral blood of colon cancer and the correlation with clinical stage .Methods The expression of PD‐L1 on CD4+CD25hiCD127low/‐Treg cells from 47 samples of the peripheral blood of colon cancer was analyzed by flow cytometry .Results Compared with those from healthy do‐nor ,the proportion of CD4+CD25hiCD127low/‐Treg cells and expression of PD‐L1 on these cells increased significantly (P<0 .01) . Further analysis showed that expression of PD‐L1 increased with the increase of clinical stage of colon cancer (P<0 .01) ,and de‐creased significantly after postoperation (P<0 .05) .Conclusion Increase of proportion of CD4+CD25hiCD127low/‐Treg cells and the expression of PD‐L1 may enhance the suppression of antitumor immunity ,and thereby promote tumor immunoescape .
