Evolutionary dynamics of heparan sulfate utilization by SARS-CoV-2

mBio
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variants have acquired enhanced infectivity compared to earlier variants. To elucidate the underlying molecular mechanisms, we conducted CRISPR library screening to identify cell ...

MASP-2 Is a Heparin-Binding Protease; Identification of Blocking Oligosaccharides

Frontiers in Immunology, 2020
It is well-known that heparin and other glycosaminoglycans (GAGs) inhibit complement activation. It is however not known whether fractionation and/or modification of GAGs might deliver pathway-specific inhibition of the complement system.

Altered distribution of heparan sulfate proteoglycans in psoriasis. [PDF]

Acta Dermato-Venereologica, 1997
Heparan sulfate proteoglycans (HSPGs) are components of the basement membrane (BM) of various tissues. They consist of a core protein and negatively charged glycosaminoglycan side chains: the heparan sulfate (HS) moieties. In psoriasis, uninvolved skin of psoriasis patients and in normal skin, the distribution of HSPGs was studied immunohistochemically

Heparan Sulfate Proteoglycans as Multifunctional Cell Regulators: Cell Surface Receptors

, 2011
Proteoglycans are macromolecules expressed on the cell surfaces and in the extracellular matrix of most animal tissues (Annu Rev Biochem 68:729-777, 1999; Int Rev Cell Mol Biol 276:105-159, 2009).

Natural Resistance to Ovarian Hyperstimulation Syndrome in Estrildid Finches Reveals Macrophage GPR183 as a Potential Therapeutic Target

Advanced Science, EarlyView.
Ovarian macrophage depletion reverses OHSS resistance in estrildid finches and exacerbates OHSS symptoms in rats. Activating macrophage GPR183 alleviates OHSS by reducing pro‐inflammatory factors, increasing immunomodulatory molecules, remodeling CD44/SDC4‐mediated communication, and restoring immune homeostasis.

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 ...

Balancing Stealth and Targetability: cCPP‐ and PEG‐Modified Liposomes for the Targeted Delivery of Anti‐HER2 Nanobodies

Advanced Science, EarlyView.
This study addresses the rapid renal clearance of anti‐HER2 nanobodies by developing specialized liposomal carriers. It details the formulation of dual modified liposomes, demonstrating how PEGylation preserves structural integrity and cell‐penetrating peptides enhance cellular interaction.

Heparan Sulfate Proteoglycan Is a Mechanosensor on Endothelial Cells [PDF]

Circulation Research, 2003
The objective of this study was to test whether a glycosaminoglycan component of the surface glycocalyx layer is a fluid shear stress sensor on endothelial cells (ECs). Because enhanced nitric oxide (NO) production in response to fluid shear stress is a characteristic and physiologically important response of ECs, we evaluated NO

THBS1+ Macrophages Exacerbate Modic Changes via SDC4‐Dependent Activation of NLRP3 Inflammasome

Advanced Science, EarlyView.
The illustration of THBS1+ macrophages exacerbate MCs via SDC4‐dependent activation of the NLRP3 inflammasome. THBS1+ macrophage subpopulation was identified in MCs through single‐cell RNA sequencing. C. acnes and its metabolites activate THBS1 expression in macrophages via the TLR signaling pathway.
