Difference in Gene Expression Profiles between Human CD4+CD25+ and CD4+CD25− T Cells

Abstract
We studied the gene expression profiles of human CD4+CD25+ and CD4+CD25− T cells by using cDNA microarrays. Our preliminary results indicate that there are likely significant differences in the regulation of apoptosis, cell cycle, cytokine receptor, cell-cell interaction, and stress pathway genes between these two subtypes of T cells.
