The results showed that there were no significant differences in the frequencies of CD4+LAP+ T cells, CD4+CD25−LAP+ T cells, CD4+CD25+ T cells, and CD4+CD25+LAP− T cells between the hypertension group and the normotension group or between the diabetes group and the nondiabetes group (see Table 3). This evidence concerns the gene CD4 and hypertensive disorder.
