Determinants of PF4/heparin immunogenicity

open access: yesBlood, 2007
Heparin-induced thrombocytopenia (HIT) is an antibody-mediated disorder that occurs with variable frequency in patients exposed to heparin. HIT antibodies preferentially recognize large macromolecular complexes formed between PF4 and heparin over a narrow range of molar ratios, but the biophysical properties of complexes that initiate antibody ...

Development of a high-yield expression and purification system for platelet factor 4

open access: yesPlatelets, 2018
Heparin-induced thrombocytopenia (HIT) is an adverse drug reaction characterized by IgG antibodies bound to complexes of platelet factor 4 (PF4) and heparin. The majority of diagnostic tests for HIT rely on an exogenous source of PF4 to identify anti-PF4/

Moving target PF4 directs HIT responses [PDF]

open access: yesBlood, 2018
In this issue of Blood, Dai et al demonstrate a dynamic interchange of cell surface-bound platelet factor 4 (PF4) among hematopoietic and vascular cells that may limit the thrombocytopenia and promote prothrombotic processes in heparin-induced thrombocytopenia (HIT).

The Binding of the SARS-CoV-2 Spike Protein to Platelet Factor 4: A Proposed Mechanism for the Generation of Pathogenic Antibodies

open access: yesBiomolecules
Pathogenic platelet factor 4 (PF4) antibodies contributed to the abnormal coagulation profiles in COVID-19 and vaccinated patients. However, the mechanism of what triggers the body to produce these antibodies has not yet been clarified.

Platelet Factor 4 Attenuates Experimental Acute Liver Injury in Mice

open access: yesFrontiers in Physiology, 2019
Platelet factor 4 (PF4) is a pleiotropic inflammatory chemokine, which has been implicated in various inflammatory disorders including liver fibrosis. However, its role in acute liver diseases has not yet been elucidated.

An affinity-based method for the purification of platelet factor 4 from outdated platelet concentrates [PDF]

open access: yesJournal of Research in Applied and Basic Medical Sciences, 2023
Background & Aims:  Platelet factor 4 (PF4) is considered as a chemokine mainly strode in the granules of platelets. Its important role in heparin-induced thrombocytopenia (HIT) was the basis of many investigations about this chemokine.

Platelet factor 4 induces bone loss by inhibiting the integrin α5‐FAK‐ERK pathway

open access: yesAnimal Models and Experimental Medicine, 2023
Background The effect of platelet factor 4 (PF4) on bone marrow mesenchymal stem cells (BMMSCs) and osteoporosis is poorly understood. Therefore, this study aimed to evaluate the effects of PF4‐triggered bone destruction in mice and determine the ...

Anti‐platelet factor 4 immunoglobulin G levels in vaccine‐induced immune thrombocytopenia and thrombosis: Persistent positivity through 7 months

open access: yesResearch and Practice in Thrombosis and Haemostasis, 2022
Background Anti‐platelet factor 4 (PF4) antibodies that activate platelets via FcγRIIA drive the pathophysiology of vaccine‐induced immune thrombocytopenia and thrombosis (VITT). Evolution of these antibodies and their ability to activate platelets after
