Butyrophilin, a Milk Protein, Modulates the Encephalitogenic T Cell Response to Myelin Oligodendrocyte Glycoprotein in Experimental Autoimmune Encephalomyelitis

Butyrophilin, a milk protein, modulates the encephalitogenic T cell response to myelin oligodendrocyte glycoprotein in experimental autoimmune encephalomyelitis.

Experimental autoimmune encephalomyelitis (EAE) induced by sensitization with myelin oligodendrocyte glycoprotein (MOG) is a T cell-dependent autoimmune disease that reproduces the inflammatory demyelinating pathology of multiple sclerosis. We report that an encephalitogenic T cell response to MOG can be either induced or alternatively suppressed as a consequence of immunological cross-reactivi...

T cell repertoire diversity is required for relapses in myelin oligodendrocyte glycoprotein-induced experimental autoimmune encephalomyelitis.

Comparison of TCRalphabeta repertoires of myelin oligodendrocyte glycoprotein (MOG)-specific T lymphocytes in C57BL/6 and TdT-deficient littermates (TdT(-/-)) generated during experimental autoimmune encephalomyelitis (EAE) highlights a link between a diversified TCRalphabeta repertoire and EAE relapses. At the onset of the disease, the EAE-severity is identical in TdT(+/-) and TdT(-/-) mice an...

Autoimmune Encephalomyelitis Glycoprotein-Induced Experimental Relapses in Myelin Oligodendrocyte T Cell Repertoire Diversity Is Required for

Antibody cross-reactivity between myelin oligodendrocyte glycoprotein and the milk protein butyrophilin in multiple sclerosis.

The etiology of multiple sclerosis (MS) is believed to involve environmental factors, but their identity and mode of action are unknown. In this study, we demonstrate that Ab specific for the extracellular Ig-like domain of myelin oligodendrocyte glycoprotein (MOG) cross-reacts with a homologous N-terminal domain of the bovine milk protein butyrophilin (BTN). Analysis of paired samples of MS se...

C3d binding to the myelin oligodendrocyte glycoprotein results in an exacerbated experimental autoimmune encephalomyelitis.

The complement system is known to contribute to demyelination in multiple sclerosis and experimental autoimmune encephalomyelitis. However, there are few data concerning the natural adjuvant effect of C3d on the humoral response when it binds to myelin Ags. This study addresses the effect of C3d binding to the myelin oligodendrocyte glycoprotein (MOG) in the induction of experimental autoimmune...
