CD4 and myeloid sarcoma: Th1 cells (CD3+CD4+IFN-γ+) increased upon rh-MOG stimulation in PBMC from MOGAD patients (means: 1.4 ± 0.74 vs. 3.3 ± 1.89; Wilcoxon-test p = 0.747) while it decreased in MS patients without reaching significance (means: 1.37± 1.08 vs. 0.37 ± 0.14; Wilcoxon-test p = 0.232) (Figure 1C).
