Frequency and phenotype of peripheral blood Tregs in SLE patients with and without abnormal carotid IMT determined by flow cytometry.

Markers for Treg detection	Abnormal carotid IMT ()	Normal carotid IMT ()	value
CD4+ (cells/μl)			<0.001
CD4+CD25+FoxP3^high (cells/μl)			0.003
CD4+CD45RA+FoxP3^low (cells/μl)			0.067
CD4+FoxP3+Helios+ (cells/μl)			0.306

Data are expressed as mean ± standard deviation; the absolute number of cells is expressed as cells/μl unit.
