... that significantly decreases the susceptibility to several bacterial infections, suggesting that subversion of Sdc1 is an important virulence strategy. HS glycosaminoglycan (GAG) chains of cell surface Sdc1 promote bacterial pathogenesis by facilitating the attachment of bacteria to host cells. Engagement of cell...

.... development differentiation embryonic stem cell glycosaminoglycan heparan sulfate signalling A key component for the ability of a cell to respond specifically to extrinsic signals is the sugar polymer HS (heparan sulfate). The GAG (glycosaminoglycan) HS is synthesized attached to protein cores...

... with particular patterns of GAG (glycosaminoglycan) expression. For example, different HS epitopes are synthesized during neural or mesodermal lineage formation. Cell lines mutant for various components of the HS biosynthetic pathway are selectively impaired in their differentiation, with lineage-specific effects...

... (glycosaminoglycan) chains are attached. The GAGs are long, linear, sulphated and highly charged heterogeneous polysaccharides that are expressed throughout the body in different forms depending on the developmental or pathological state of the organ/organism. Mechanistically, the GAG interaction is thought...

... the protease network through inhibition of plasmin. TSG-6 binds a wide range of GAGs (glycosaminoglycans) [i.e. HA (hyaluronan), chondroitin 4-sulphate, dermatan sulphate, heparin and heparan sulphate] as well as a variety of protein ligands, where these interactions can influence the activities of TSG-6...

...B. Mulloy; C.C. Rider The defining characteristic of the glycoproteins known as proteoglycans is the presence of O-linked acidic polysaccharides known as GAGs (glycosaminoglycans). The backbone of these linear polysaccharides is a repeating disaccharide, comprising N -acetyl hexosamine alternating...

In addition to the high-affinity receptor interaction, chemokines have an in vivo requirement to bind to GAGs (glycosaminoglycans) in order to mediate directional cell migration. Prevention of the GAG interaction has been shown...

... glycosaminoglycans can act as important cofactors or modulators of PrP-res formation in vivo . In an effort to develop therapeutics, the antimalarial drug quinacrine was identified as an inhibitor of PrP-res formation in scrapie-infected cell cultures. Confirmation of the latter result by others has led...
