Abstract: Objectives The aim of the study was to detect the frequency of B regulatory cells (Breg)and the correlation between Breg and T regulatory cells (Treg) in pancreatic cancer patients,and to investigate its role in pathogenesis of pancreatic cancer.Methods 50 pancreatic cancer patients and 21 healthy controls were enrolled.CD19+CD24hiCD38hi Breg and CD4+CD25high Treg was also determined via flow cytometry.The correlation between Breg and Treg was analyzed by Spearman correlation test.Results Upregulation of CD19+CD24hiCD381hi Breg was associated with pancreatic cancer progression.Furthermore,this B cell subset was positively correlated with the frequency of CD4 + CD25high Treg cells.Conclusions Together,CD19 + CD24hiCD38hi Breg cells are significantly elevated in pancreatic cancer patients,indicating this B cell subset might play an vital role in clinical progression of pancreatic cancer.The significant positive correlation between Breg and Treg may suggest CD 1TCD24hiCD38hi Breg are affecting tumor progression through Treg cells.
