  Platelet Factor 4 (PF4) is a non-ELR type of CXC chemokine. PF4 is expressed primarily in megakaryocytes and platelets, but it is also seen in a variety of other cells as well. It is released from alpha granules of activated platelets during platelet aggregation and binds to heparin with high affinity, neutralizing the anticoagulant effect of heparin. Because of this coagulation-promoting activity, it is concluded that PF4 is involved in inflammation and would healing. PF4 binds to the integral membrane protein receptor CXCR3B, an alternatively spliced isoform of CXCR3. It participates in chemotaxis of neutrophils, fibroblasts, and monocytes.
