) peptides, tau protein, and other important proteins involved in AD pathogenesis, have altered glycosylation profiles. Crucially, these abnormalities present early in the disease state, are present in the peripheral blood, and help to distinguish AD from other dementias. This review describes the aberrant glycome in AD, focusing on proteins implic...

Most commercialized virus-like particle (VLP) vaccines use aluminum salt as adjuvant, even though VLPs provoke adequate antibody responses without adjuvant. We do not have detailed knowledge of how adjuvant affects the profile of anti-VLP antibodies. Meanwhile, there is evidence that differences between vaccination protocols influence the glycosyla...
Modifizierte Nukleoside sind wichtige Medikamente zur Behandlung von Krebs, viralen oder bakteriellen Infektionen. Sie dienen auch als Vorläufer für die Synthese von modifizierten Oligonukleotiden (Antisense-Oligonukleotide (ASOs) oder short-interfering RNAs (siRNAs)), einer neuen und sehr effektiven Klasse von Therapeutika. Während die chemische S...
Using a halogen bond (XB) donor and Schreiner's thiourea as cooperative catalysts, various amides, including the asparagine residues of several peptides, were directly coupled with glycosyl trichloroacetimidates to give unique N‐acylorthoamides in good yields. Synthetic applications of N‐acylorthoamides, including rearrangement to the corresponding...

Understanding of the functioning of MUC1 (human mucin) has advanced significantly over 40 years of its investigation. The anti-adhesive properties of the extracellular domain, which were the main focus of early studies initially explaining overexpression of MUC1 in progressing oncological diseases, were gradually put on the back burner. Researchers...

Chemical glycosylations occupy a central importance to synthesize tailor-made oligo- and polysaccharides of functional importance. Generation of the oxocarbenium ion or the glycosyl cation is the method of choice in order to form the glycosidic bond interconnecting a glycosyl moiety with a glycosyl/aglycosyl moiety. A number of elegant methods have...
Genetic variants in Fukutin-related protein (FKRP), an essential enzyme of the glycosylation pathway of α-dystroglycan, can lead to pathologies with different severities affecting the eye, brain, and muscle tissues. Here, we generate an in vitro cellular system to characterize the cellular localization as well as the functional potential of the mos...

Glycosylation of 4-(4-hydroxyphenyl)-1,2,3-thia(selena)diazoles with 1-α-bromo-2,3,4,6-tetra-O-acetyl-D-glucopyranose, 1-α-bromo-2,3,4,6-tetra-O-acetyl-D-galactopyranose, and 1-α-bromo-2,3,5-tri-O-acetyl-D-xylopyranose under the conditions of interphase catalysis has afforded the corresponding acetylated glycosides. An alternative pathway of selena...
Due to their capacity to process different proteins of the extracellular matrix (ECM), matrix metalloproteinases (MMPs) were initially described as a family of secreted proteases, functioning as main ECM regulators. However, through proteolytic processing of various biomolecules, MMPs also modulate intra- and extracellular pathways and networks. Th...
Antibodies are immunoglobulins that play essential roles in immune systems. All antibodies are glycoproteins that carry at least one or more conserved N-linked oligosaccharides (N-glycans) at the Fc domain. Many studies have demonstrated that both the presence and fine structures of the attached glycans can exert a profound impact on the biological...
