Interplay between inflammation and thrombosis in cardiovascular pathology.

Nat Rev Cardiol 2021 May 6. Epub 2021 May 6.

Medizinische Klinik und Poliklinik I, University Hospital, LMU Munich, Munich, Germany.

Thrombosis is the most feared complication of cardiovascular diseases and a main cause of death worldwide, making it a major health-care challenge. Platelets and the coagulation cascade are effectively targeted by antithrombotic approaches, which carry an inherent risk of bleeding. Moreover, antithrombotics cannot completely prevent thrombotic events, implicating a therapeutic gap due to a third, not yet adequately addressed mechanism, namely inflammation. Read More

A PSGL-1 Glycomimetic Reduces Thrombus Burden Without Affecting Hemostasis.

Blood 2021 May 4. Epub 2021 May 4.

Harvard Medical School, Atlanta, Georgia, United States.

Events mediated by the P-selectin/PSGL-1 pathway play a critical role in the initiation and propagation of venous thrombosis by facilitating the accumulation of leukocytes and platelets within the growing thrombus. Activated platelets and endothelium both express P-selectin, which binds PSGL-1 expressed on the surface of all leukocytes. We developed a pegylated glycomimetic of the N-terminus of PSGL-1, PEG40-GSnP-6 (P-G6), which proved to be a highly potent P-selectin inhibitor with a favorable pharmacokinetic profile for clinical translation.
