Plasma 25(OH)D concentrations in patients with or without T-cell proliferation against myelin peptides. RRMS patients were grouped according to negative or positive T-cell reactivity. During winter, RRMS patients with positive T-cell proliferation had lower plasma 25(OH)D concentrations (mean + SD) than patients with negative T-cell proliferation (p = 0.006).
