What is it about?

Endothelial cells are the primary targets of heparin-binding protein (HBP) released in the circulation and this protein plays a major role in the mechanism of capillary leakage, while it amplifies inflammatory effects. This study aimed to examine the relevance of the novel inflammatory factor HBP in critically ill COVID-19 patients, and evaluate the correlation of the biomarker with disease progression.

Why is it important?

For the first time, this study found that HBP levels were associated with COVID-19 disease progression in critically ill patients.

Perspectives

As a potential mediator of disease aggravation and multiple organ injuries that are triggered by continuing inflammation and oxygen deficits, HBP warrants further study as a disease biomarker and potential therapeutic target.
