Comparisons of the percentages of CD3⁺CD25⁺(a), CD3⁺CD69⁺(b), and CD3⁺HLA-DR⁺(c) T lymphocytes in unstimulated (medium alone) and stimulated (naeduimt + PHA) cell cultures from patients with familial Mediterranean fever (FMF) and controls. Results presented are based on analysis of 26 patients with FMF in an attack-free period, 15 patients with FMF in an attack period, 20 healthy and 15 disease controls. Bars represent arithmetic mean ± standard deviation. The differences between two groups were evaluated by Mann–Whitney U-test. P-values are indicated above the bars when a level of significance < 0·05 was reached in comparisons of study groups. CD: cluster of differentiation, HC: healthy controls, BD: Behçet's disease.
