Heparan sulfate modulates neutrophil and endothelial function in antibacterial innate immunity [PDF]

, 2015
Recently, we showed that endothelial heparan sulfate facilitates entry of a bacterial pathogen into the central nervous system. Here, we show that normal bactericidal activity of neutrophils is influenced by the sulfation pattern of heparan sulfate ...

The β-d-Endoglucuronidase Heparanase Is a Danger Molecule That Drives Systemic Inflammation and Correlates with Clinical Course after Open and Endovascular Thoracoabdominal Aortic Aneurysm Repair: Lessons Learnt from Mice and Men

Frontiers in Immunology, 2017
Thoracoabdominal aortic aneurysm (TAAA) is a highly lethal disorder requiring open or endovascular TAAA repair, both of which are rare, but extensive and complex surgical procedures associated with a significant systemic inflammatory response and high ...

Syndecan-1 downregulates syndecan-4 expression by suppressing the ERK1/2 and p38 MAPK signaling pathways in cultured vascular endothelial cells

Biochemistry and Biophysics Reports, 2021
Syndecan-1 and syndecan-4 are members of the syndecan family of transmembrane heparan sulfate proteoglycans. Vascular endothelial cells synthesize both species of proteoglycans and use them to regulate the blood coagulation-fibrinolytic system and their ...

Charge Characteristics of Agouti-Related Protein Implicate Potent Involvement of Heparan Sulfate Proteoglycans in Metabolic Function. [PDF]

, 2019
The endogenous melanocortin peptide agouti-related protein (AgRP) plays a well-known role in foraging, but its contribution to metabolic regulation is less understood.

Immunopurification and characterization of a neuronal heparan sulfate proteoglycan [PDF]

The Journal of Neuroscience, 1985
We have identified a unique heparan sulfate (HeS) proteoglycan synthesized by the neuronal-like cell line PC12. The proteoglycan, purified with monoclonal antibodies from medium conditioned by PC12 cells, has an apparent molecular weight of 350,000, and it contains a Mr 80,000 core protein and HeS side chains of Mr 15,000 each.

Glypican-1, Phosphacan/Receptor Protein-Tyrosine Phosphatase-ζ/β and its Ligand, Tenascin-C, are Expressed by Neural Stem Cells and Neural Cells Derived from Embryonic Stem Cells

ASN Neuro, 2010
The heparan sulfate proteoglycan glypican-1, the chondroitin sulfate proteoglycan phosphacan/RPTP (receptor protein-tyrosine phosphatase)-ζ/β and the extracellular matrix protein tenascin-C were all found to be expressed by neural stem cells and by ...

A monoclonal antibody against a laminin-heparan sulfate proteoglycan complex perturbs cranial neural crest migration in vivo [PDF]

, 1988
INO (inhibitor of neurite outgrowth) is a monoclonal antibody that blocks axon outgrowth, presumably by functionally blocking a laminin-heparan sulfate proteoglycan complex (Chiu, A. Y., W. D. Matthew, and P. H. Patterson. 1986. J. Cell Biol.

Viral pathogens hitchhike with insect sperm for paternal transmission

Nature Communications, 2019
Arbovirus vertical transmission is commonly mediated by transovarial passage of female insect vectors. Here, the authors show that Rice gall dwarf virus can be transmitted by male leafhoppers via interactions of the viral capsid and heparan sulfate ...

Inhibition of Heparan Sulfate and Chondroitin Sulfate Proteoglycan Biosynthesis [PDF]

Journal of Biological Chemistry, 2008
Proteoglycans (PGs) are composed of a protein moiety and a complex glycosaminoglycan (GAG) polysaccharide moiety. GAG chains are responsible for various biological activities. GAG chains are covalently attached to serine residues of the core protein. The first step in PG biosynthesis is xylosylation of certain serine residues of the core protein.

The Production of a Monoclonal Antibody That Blocks the Action of a Neurite Outgrowth-promoting Factor [PDF]

, 1983
How growing axons are guided to their targets has been the subject of much speculation. A popular hypothesis is that there are macromolecules in the extracellular matrix (ECM) or on the surfaces of other cells that form pathways for axon guidance.
