Abstract:
:In view of the hypothesis that a biochemical abnormality in the childhood forms of neuronal ceroid-lipofuscinosis may lie in the utilization of dolichols in glycoprotein synthesis, we analyzed the oligosaccharide structures of brain glycoproteins in infantile neuronal ceroid-lipofuscinosis (INCL). Lectin affinity chromatography of purified glycopeptides and of oligosaccharides prepared by hydrazinolysis showed an increase in high mannose-type glycopeptides and a decrease in tri- and tetra-antennary glycopeptides in INCL brain when compared with control brain. These changes were more pronounced in the storage cytosomes than in whole brain. Methylation analysis of the isolated glycopeptide fractions did not reveal differences in substitution patterns of the individual sugar residues between INCL and control brain. In INCL the core disaccharide of the O-glycosidically-linked oligosaccharides was sialylated to a higher degree than in control brain indicating that the structural changes were not confined only to N-glycosidically-linked carbohydrate chains. The observed structural changes in the carbohydrate chains of brain glycopeptides in INCL could be explained by a defect in the biosynthesis of glycoproteins. Alternatively, the changes may reflect the increased glial cell population in the degenerating brain. In fact, the elution profiles in lectin chromatography of oligosaccharides prepared from cultured rat glioma cells resembled those from INCL brain.
