EFNB3 and myeloid sarcoma: There was a non-significant trend towards increased ephrin-B3-positive cells among T cells of patients with RR-MS, but the values of CD8+ T cells (4.6 ± 0.9%), Tregs (2.6 ± 0.4%), Th1 (2.4 ± 0.3%), Th2 (1.2 ± 0.3%) and Th17 (1.9 ± 0.4%) cells were significantly higher than in HC (1.9 ± 0.6%, p = 0.0132; 1.6 ± 0.3%, p = 0.050; 1.4 ± 0.3%, p = 0.023; 0.4 ± 0.1, p = 0.037 and 0.7 ± 0.2, p = 0.031, respectively, Figure 2D).
