Application Note
As reported recently in the Wall Street Journal and other publications, the human chemokine CXCL4 (also known as platelet factor 4 or PF4) is the common link between COVID-19 vaccine-induced immune thrombotic thrombocytopenia (VITT) and a more common condition known as heparin-induced thrombocytopenia (HIT).

Using a hybrid modeling approach, Fox generated a model for the chemokine XCL1 in complex with its G protein-coupled receptor XCR1 and identified key interaction sites. Changes within a region of XCL1 that determined its binding energy to XCR1 changed the activity of the receptor and,
consequently, cell migration
