    The presence of MOG antibodies is unlikely to have therapeutic implications in the first demyelinating event but is more likely to be therapeutically important in the relapsing patient.Although recent patients fulfilled criteria for MS, the presence of MOG antibodies and elevated ESR led us to treat them more like NMO patients with the immune suppression agent MMF rather than conventional MS diseasemodifying therapies.Both patients had no clinical or radiologic relapse for months and months, respectively, and both became MOG antibody seronegative.Further studies are required to understand the longitudinal course of patients with MOG antibodyassociated relapsing disease and the treatment approach required.Supporting this concept, none of the patients with positive MOG antibody had intrathecal oligoclonal bands.Unauthorized reproduction of this article is prohibited.MOG antibody against the conformational native form of the antigen has enabled pathogenic studies using native MOG antibody from patient sera.We also observed a fast effect after short incubation times that may be due to high expression of surface MOG in transduced cells.Despite the significant alteration in cytoskeleton, no cell death occurred, as previously observed in animal models.Our findings add to the pathogenic potential of MOG antibody, and it is conceivable that different pathogenic effects may be present in different patients.Recent studies have shown that different patients have different epitopes involved in antibody binding that may influence pathogenic properties of MOG antibody.A monoclonal antibody against a myelin oligodendrocyte glycoprotein induces relapses and demyelination in central nervous system autoimmune disease.Published since April, it is an openaccess, onlineonly, continuous publication journal.Published since April, it is an openaccess, onlineonly, continuous publication journal.All rights reserved.

Recent advances have provided insights into mechanisms underlying the ability of integrins, cadherins, selectins, and other cell adhesion molecules to regulate signal transduction cascades.These mechanisms often involve the ability of cell adhesion molecules to initiate the formation of organized structures or scaffolds that permit the efcient ow of information in signaling pathways.Over the last decade, however, it has become apparent that adhesion molecules play far more than a structural role and indeed are Ondansetron hydrochloride critically involved in multiple signal transduction processes.Thus, aspects of cell adhesion research now overlap with one of the key themes of pharmacological research, namely that of understanding the mechanistic bases of signaling cascades.This review addresses selected aspects of the recent literature in this rapidly evolving eld, concentrating on themes that the author views as being particularly novel or critically important to the future development of this area of research.Although a young eld, there is already a vast literature dealing with various aspects of cell adhesion and signaling.More importantly it deals with the mechanistic basis of cooperation between cell adhesion receptors and conventional signaling receptors, such as receptor tyrosine kinases.There is a growing awareness that such cooperation involves the formation of scaffolds that efciently organize the intracellular components of signaling cascades.Furthermore, it seems likely that elements of the actincontaining cytoskeleton are essential in the formation of such scaffolds; however, the molecular details have yet to be elucidated, and this will be a key issue for future progress.
