MOG1

Introduction

In MS, the immune system attacks the protective sheath (myelin) that covers nerve fibers and causes communication problems between your brain and the rest of your body. Eventually, the disease can cause the nerves themselves to deteriorate or become permanently damaged.

In MS disease, T cells attack 3 types of glycoprotein:

1) Myelin basic protein (MBP)

2) Proteolipid protein (PLP)

3) myelin oligodendrocyte glycoprotein (MOG)

Experimental autoimmune encephalomyelitis (EAE)

EAE is a CD4' T cell-mediated inflammatory disease of the central nervous system (CNS) induced in experimental animals with CNS homogenate, myelin or myelin components. In its chronic form, EAE is a well accepted experimental model for multiple sclerosis (MS).

Epitopes

MOG glycoprotein is the only CNS autoantigen known to induce both a T-cell response and a demyelinating autoantibody response in EAE

Therefore, we chose the three epitopes that induced the most significant immune response. MOG1 is the first epitope that appears in the MOG glycoprotein (1-21)
