Involvement of OSP/claudin-11 in oligodendrocyte membrane interactions: Role in biology and disease

Abstract

Oligodendrocyte-specific protein (OSP/claudin-11) is a four transmembrane protein concentrated in central nervous system myelin. Recent evidence has emerged suggesting that OSP/claudin-11 is involved in membrane interactions at tight junctions and with the extracellular matrix. OSP/claudin-11 seems to modulate proliferation and migration of oligodendrocytes presumably through these interactions. Furthermore, evidence is presented implicating OSP/claudin-11 as an autoantigen in the development of autoimmune demyelinating disease. (C) 2000 Wiley-Liss, Inc.
