Journal Article
Yusuf, M. Z., Raslan, Z., Atkinson, L., Aburima, A., Thomas, S. G., Naseem, K. M., & Calaminus, S. D. (2017). Prostacyclin reverses platelet stress fibre formation causing platelet aggregate instability. Scientific reports, 7(1), https://doi.org/10.1038/s41598-017-05817-9

Prostacyclin (PGI2) modulates platelet activation to regulate haemostasis. Evidence has emerged to suggest that thrombi are dynamic structures with distinct areas of differing platelet activation. It was hypothesised that PGI2 could reverse platelet... Read More about Prostacyclin reverses platelet stress fibre formation causing platelet aggregate instability.

Oxidized low-density lipoprotein (oxLDL) promotes unregulated platelet activation in dyslipidemic disorders. Although oxLDL stimulates activatory signaling, it is unclear how these events drive accelerated thrombosis. Here, we describe a mechanism fo...

Introduction Idiopathic Pulmonary Fibrosis (IPF) is a progressive, incurable fibrotic interstitial lung disease with a prognosis worse than many cancers. Its pathogenesis is poorly understood. Activated platelets can release pro-fibrotic mediators th... Read More about Increased platelet reactivity in idiopathic pulmonary fibrosis is mediated by a plasma factor.
