The distribution of LAP+CD4+ T cells in gastric carcinoma microenvironment and its clinical significance / 中国医师进修杂志

ABSTRACT

Objective To investigate the distribution of LAP+CD4+T cells in gastric carcinoma microenvironment and the correlation of LAP + CD4 + T cells with the progression of gastric tumor. Methods Forty gastric tumor patients and 20 healthy donors were enrolled in this study. The percentage of LAP+CD4+T cells in the peripheral blood and tumor tissue was detected by flow cytometry. The correlation of LAP+CD4+T cells with the progression of gastric tumor was analyzed. Results The percentage of LAP+CD4+T cells in the peripheral blood of gastric tumor patients was higher than that of health donors:(10.9±3.3)%vs. (4.3 ± 1.2)%;the percentage of LAP+CD4+T cells from tumor tissue was higher than that from non-tumor tissue:(13.5 ± 5.3)%vs. (4.7 ± 1.4)%. The percentage of LAP+CD4+T cells in peripheral blood from metastasis patients was higher than that from non-metastasis patients and health donors: (10.1 ± 6.4)% vs. (4.5 ± 1.3)% and (4.3 ± 1.2)%. Conclusions LAP+ CD4+ T cells accumulates in gastric carcinoma microenvironment and the percentage of LAP+CD4+T cells increases along with the progression of gastric tumor.
