Heparan sulfate (HS) is a complex, polyanionic polysaccharide ubiquitously expressed on cell surfaces and in the extracellular matrix[1]. Heparan sulfate interacts with numerous proteins, including growth factors, morphogens, and adhesion molecules, and thereby regulates important developmental processes in invertebrates and vertebrates[6]. Heparan sulfate proteoglycans can act as receptors for proteases and protease inhibitors regulating their spatial distribution and activity. Membrane Heparan sulfate proteoglycans act as coreceptors for various tyrosine kinase-type growth factor receptors, lowering their activation threshold or changing the duration of signaling reactions[5].
Heparan sulfate treatment significantly reduced SARS-CoV-2 replication in cell lysates and supernatant samples of Calu3 and Caco2. HS serves as an essential host determinant during SARS-CoV-2 attachment and replication[2].Heparan sulfate influences the binding affinity of intestinal epithelium cells to Wnt, thereby promoting activation of canonical Wnt signaling and facilitating regeneration of small intestinal crypts after epithelial injury[7].
In Sprague-Dawley male rats, FGF-2/FGFR system is involved in the regulation of astrocytic reactivity and/or proliferation in the brain and its action is potentiated by Heparan sulfate [3].Heparan sulfate proteoglycans represent a major component of the extracellular matrix and are critical for brain development, Heparan Sulfate can maintain neuronal excitability, promote synaptic plasticity and learning[5].
