SARS-CoV-2 is the coronavirus that causes COVID-19. It is currently not known why some individuals develop only mild or no symptoms when infected, whilst others experience severe, life-threatening forms of the disease. However, it is known that the risk of COVID-19 becoming severe increases with age and is higher in males than in females. Many severe COVID-19 cases are characterised by increased blood clotting and thrombosis formation.

The team combined existing data on gene expression in humans with cell culture research of SARS-CoV-2-infected cells to search for molecules involved in blood coagulation that differ between females and males, change with age, and are regulated in response to SARS-CoV-2 infection.

Out of more than 200 candidate factors, researchers identified a glycoprotein called transferrin to be a procoagulant (a cause of blood clotting) that increases with age, is higher in males than in females, and is higher in SARS-CoV-2-infected cells. Hence, transferrin may have potential as a biomarker for the early identification of COVID-19 patients at high risk of severe disease.
