CD4+ T-cell reactivity to MOG peptides in participants with AQP4-Ab (n = 5), MOG-Ab (n = 10), MS (n = 8) and HC (n = 14). (A) CD4+ T-cell proliferation after challenging with respective MOG peptides and the positive control TTX. The cut-off value of a CDI ≥ 3 is indicated by a gray dashed line. Secretion of GM-CSF (B), IFN-γ (C) and IL-6 (D) after challenging with respective MOG peptides and the positive control TTX. The cut-off value of a SI ≥ 3 is indicated by a gray dashed line. AQP4-Ab, aquaporin-4 antibody positive; CDI, cell division index; GM-CSF, granulocyte-macrophage-colony-stimulating factor; HC, healthy controls; IFN, interferon; IL, interleukin; MOG-Ab, myelin oligodendrocyte glycoprotein antibody positive; MS, multiple sclerosis; SI, stimulation index; TTX, tetanus toxoid.
