Endothelial cell expression of the intercellular adhesion molecule-1 (ICAM-1) in the central nervous system of guinea pigs during acute and chronic relapsing experimental allergic encephalomyelitis.

This study investigated the expression of intercellular adhesion molecule-1 (ICAM-1; CD54) by cells of the central nervous system (CNS) during acute experimental allergic encephalomyelitis (EAE) and chronic relapsing EAE (CREAE). In the CNS of normal guinea pigs, only a few endothelial cells expressed detectable levels of ICAM-1, whereas during the active phases of the disease ICAM-1 was present on cells of the perivascular infiltrate and the endothelia of both lesion- and non-lesion-associated blood vessels. In addition, cultured cerebrovascular endothelia maintained in 'standard' culture medium did not express ICAM-1, but they could be induced to express this antigen on incubation in a lymphocyte-conditioned medium. These findings suggest that the induction of ICAM-1 on CNS endothelia may be important in antigen presentation or in promoting lymphocyte extravasation across the blood-brain barrier in inflammatory disorders of the CNS.[1]
