Heparan sulphate proteoglycans fine-tune mammalian physiology

Joseph R BishopJeffrey D Esko


Heparan sulphate proteoglycans reside on the plasma membrane of all animal cells studied so far and are a major component of extracellular matrices. Studies of model organisms and human diseases have demonstrated their importance in development and normal physiology. A recurrent theme is the electrostatic interaction of the heparan sulphate chains with protein ligands, which affects metabolism, transport, information transfer, support and regulation in all organ systems. The importance of these interactions is exemplified by phenotypic studies of mice and humans bearing mutations in the core proteins or the biosynthetic enzymes responsible for assembling the heparan sulphate chains.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
