Platelet-derived exerkine CXCL4/platelet factor 4 rejuvenates hippocampal neurogenesis and restores cognitive function in aged mice [PDF]
The beneficial effects of physical activity on brain ageing are well recognised, with exerkines, factors that are secreted into the circulation in response to exercise, emerging as likely mediators of this response.

Interactions of marine sulfated glycans with antithrombin and platelet factor 4 [PDF]
The molecular interactions of sulfated glycans, such as heparin, with antithrombin (AT) and platelet factor 4 (PF4) are essential for certain biological events such as anticoagulation and heparin induced thrombocytopenia (HIT).

Novel adenovirus vaccine vectors lacking thrombosis-associated interactions with platelet factor 4 [PDF]
Summary: The adenoviral vector-based AstraZeneca and Janssen COVID-19 vaccines have been associated with rare cases of thrombosis, believed to be triggered, among other factors, by vector binding to the blood protein platelet factor 4 (PF4).

Platelet factor 4 induces bone loss by inhibiting the integrin α5‐FAK‐ERK pathway [PDF]
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 ...
