Regulatory T Cells and Profile of FOXP3 Isoforms Expression in Peripheral Blood of Patients with Myelodysplastic Syndromes

Table 3

The absolute number of cell populations in the peripheral blood of patients with MDS and age-matched healthy donors (10⁹ cells/L).

Group	Leukocytes	Lymphocytes	CD4^+ Т cells
Age control, n=26	6.15 (5.4–7.7)	2.0 (1.7–2.4)	0.8 (0.6–1.0)
MDS-primary^1, n=21	4.1 (3.0–5.8)	1.6 (1.2–2.6)	0.5 (0.4–0.9)
E-MDS^2, n=27	3.1 (2.0–3.9)	1.2 (0.9–1.5)	0.4 (0.3–0.6)
L-MDS^3, n=28	2.6 (1.7–3.9)	1.1 (0.8–2.1)	0.4 (0.2–0.6)

Note: p<0.05 rel. to age control; p<0.001 rel. to age control; p<0.05 rel. to MDS-primary. ¹MDS-primary, primary myelodysplastic syndrome; ²E-MDS, early-stage myelodysplastic syndrome; ³L-MDS, late-stage myelodysplastic syndrome.
