New study pinpoints blood biomarkers behind long COVID’s lung damage

A recent study from Karolinska Institutet identifies specific blood biomarkers linked to long COVID, particularly in patients with severe respiratory symptoms. Researchers discovered a distinct plasma biomarker signature involving proteins like CCL3 and IL-18, associated with cell death, lung injury, and platelet activation. These findings offer potential for improved diagnosis and targeted therapies for long COVID respiratory issues.
