摘要:
Antisense technologies for the targeted inhibition of gene expression could provide an effective strategy for the suppression of inflammation. However, the effective use of antisense oligonucleotides (ODN) has been limited because of several problems. Therefore, a delivery system for antisense ODNs that enhances antisense stability, while maintaining the specificity of antisense for its target RNA or DNA is needed. We have developed a delivery system for antisense ODN using schizophyllan (SPG), a polysaccharide that belongs to the beta-(1-3) glucan family. This system has several advantages enabling the effective suppression of targeted RNA or DNA: the SPG complex is stable in vivo and does not dissolve in the presence of deoxyribonuclease, and the SPG complex is effectively taken up into macrophages by phagocytosis through Dectin-1. Macrophage-migration inhibitory factor (MIF), which is mainly produced by macrophages has been shown to have a pathogenetic role in inflammatory bowel disease (IBD). We developed a technique to create an SPG complex that highly conformed to the antisense MIF. The administration of antisense MIF/SPG complex effectively suppressed MIF production and significantly ameliorated intestinal inflammation. Our result demonstrated a possible new therapeutic approach, i.e., the administration of antisense MIF/SPG complex, for the treatment of IBD.
