Healthy Donor Red Blood Cells Have Unique Glycan Fingerprints (click for authors’ abstract):<\/a><\/p>\n

Background\/Case Studies: Lectins are glycan recognizing proteins, some of which can distinguish between ABO blood types. Lectin arrays provide an extensive set of glycan probes for rapid analysis of biological samples. Red blood cells contain a variety of surface glycans that, in combination, act a as unique signature. Our aim was to create a healthy donor red blood cell database of glycan fingerprints by ABO blood type and data mine unique glycan signatures attributed to the donors.<\/p>\n

Interplay between protein glycosylation<\/span> pathways in Alzheimer’s disease (click for authors’ abstract):<\/a><\/strong><\/p>\n

Deviations from the normal nucleoplasmic protein O-GlcNAcylation, as well as from normal protein sialylation and N-glycosylation<\/span> in the secretory pathway, have been reported in Alzheimer’s disease (AD). However, the interplay between the cytoplasmic protein O-GlcNAcylation and the secretory N-\/O-glycosylation<\/span> in AD has not been described.\u00a0 We present a comprehensive analyisi of the N-, O-, and O-GlcNAc-glycomes in AD-affected brain regions as well as in AD patient serum.\u00a0 We detected marked differences in levels of glycan involved in both protein O-GlcNAcylation and N-\/O-glycosylation<\/span> between patients and healthly individuals and revealed brain region-specific glycosylation<\/span>-relation pathology in patients.\u00a0 These alterations are not general for other neurodegenerative conditions, such as frontotemporal dementia and corticbasal degeneration.\u00a0 The alteraions in the AD glycome in the serum could potentially lead to novel glyco<\/span>-based biomarkers for AD progression.\u00a0 Strikingly, negative interrelationship was found between the pathways of protein O-GlcNAcylation and N-\/O-glycosylation<\/span>, suggesting a novel intracellular cross-talk.<\/p>\n

The utility of lectin microarray in monitoring terminal galactosylation and sialylation of glycoproteins:<\/a><\/h1>\n

All living cells assemble a diverse repertoire of glycan structures on their surface via their glycosylation<\/span> machinery.<\/p>\n

With recent advances in glycobiology, cell-surface glycosylation<\/span> and lectin-glycan signaling have been shown to play critical roles in immune response and cell-to-cell and cell-pathogen interactions.<\/p>\n

Glycan structure alterations have been identified as biomarkers for cancer and have been utilized to design carbohydrate-based therapeutic vaccines.<\/p>\n

Several tools are being developed for glycan profiling based on chromatography and mass spectrometry, however, these technologies require a large amount of the samples, which is often not possible from clinical specimens.<\/p>\n
