RESUMEN
Objective To investigate the expression of galectin-10 in CD4+CD25+CD127low/-regulatory T cells(Treg) and the correlation between expressions of galectin-10 and Foxp3.Methods CD4+CD25+CD127low/-Treg cells and CD4+CD25-CD127+ T cells were isolated from PBMC of healthy volunteers and lymph nodes of gastric cancer patients by flow cytometry.Following RNA micro-extraction RT-PCR analysis was used to detect mRNA expression of galectin-10 and Foxp3.Results The mRNA expression of galectin-10 and Foxp3 were dominant in Treg cells,whereas nearly no expression in CD4+CD25-CD127+ T cells.The results from PBMC of healthy volunteers and lymph nodes of gastric cancer patients were consistent between.Conclusion The expression of galectin-10 was obviously high in Treg cells,so it may become a novel marker for phenotypic characterization of Treg cells.
