Abstract:
Objective:To explore the influence of tumor cells on CD4+CD25+Treg cells via TLRs.Methods:The numbers changes of CD4+CD25+Treg cells in the co-culture system of Lewis lung cancer cells and splenic lymphocytes were detected by flow cytometry;The expression of Foxp3 and TLR1-9 mRNA after co-culture were detected by RT-PCR;TLR9 expression on Lewis lung cancer cells was blocked by TLR9 receptor antagonist chloroquine.Results:Compared with control group,the number of CD4+CD25+Treg cells and Foxp3 mRNA expression were significantly increased in the co-culture group(P
