In the 3 index patients, the decision to test for antibodies to platelet factor 4 (PF4) was based on the ... receptor-binding domain (RBD), and nucleocapsid protein; levels of functional ...

Furthermore, various studies have reported stimulation of tumor necrosis factor-α (TNF-α), platelet factor 4 (PF4), interleukin ... CoV-2 S receptor-binding domain (RBD) protein.

The level of anti–PF4–heparin antibodies was measured with the use of an enzyme-linked immunosorbent assay (ELISA), and the levels of antibodies against various antigenic sites of the SARS-CoV ...

Studies suggest that some inoculated people develop an immune response that attacks a protein called platelet factor 4 or PF4, which makes platelets form clots. Those platelets get used up before ...

Joint studies conducted by teams from the University of California San Francisco (UCSF) and the University of Queensland have highlighted platelet factor 4 (PF4) as the linked factor behind these ...

They've discovered that platelets secrete a protein, exerkine CXCL4/Platelet factor 4 or PF4, that rejuvenates neurons in aged mice in a similar way to physical exercise. This protein, which is ...

In vivo platelet activation and related pathways may be linked to small airways disease and pulmonary vascular changes in smokers.
