Fibrin deposition and impaired fibrinolysis has long been implicated as a driver of chronic inflammation secondary to loss of vascular integrity in a large number of central nervous system (CNS) and peripheral inflammatory diseases. However, a lack of understanding of the cellular and molecular innate immune mechanisms responsible for fibrin-driven inflammation and an inability to target the inflammatory aspects of fibrin, while sparing any downstream impact on its role in hemostasis has prevented therapeutic intervention along this axis.
We are harnessing the unique insights that we possess at Therini Bio along with our founder, Dr. Katerina Akassoglou, Senior Investigator, Gladstone Institutes and Professor of Neurology, UCSF, to progress fibrin-targeting therapies that solve for these issues. Our therapies block fibrin-mediated inflammatory activation of the innate immune system specifically in diseased tissue, sparing any systemic immunosuppression to the patient, and without any impact on the hemostatic function of fibrin.
