Fig 1: IgG reactivity to BTN1A1 and MOG in MS patients and healthy controls. (A) Spearman’s correlation between the occurance of IgG to milk fat globule membrane protein BTN1A1 and MOG in MS patients (N = 35) or healthy controls (N = 20). Correlation coefficient (r) and the corresponding significance (P) are displayed in the graph. (B) IgG titers to BTN1A1 and MOG are shown for MS (N = 35) vs. healthy controls (N = 20). BTN1A1, butyrophilin; MOG, myelin oligodendrocyte glycoprotein; OD, optical density.
