This review focuses on recent advances in understanding the CD4+ CD25+ regulatory T cells, chemokine and receptor, chemokine receptor expressing on CD4+ CD25+ Tr cells and the attraction of these cells by antigen presenting cells (APCs).

• 了解CD4+CD25+Tr细胞、趋化性细胞因子、趋化性细胞因子受体和表达于CD4+CD25+Tr细胞上的趋化性细胞因子受体以及它们与不同的抗原提呈细胞(APCs)之间的作用的最新研究进展十分必要。
