Professor Wolfram Ruf, MD
Professorship for Cell Signaling Pathways of the Hemostatic System

The hemostatic system is comprised of the coagulation and fibrinolytic protease cascades, platelets, and cellular receptors on immune and vascular cells. The hemostatic response to infection and tissue injury supports inflammatory and immune reactions, but the coagulation pathways are increasingly recognized as major players and molecular targets for interventional therapy in cancer progression, atherosclerosis, chronic inflammatory disorders, and the metabolic syndrome associated with obesity. We are interested in the crosstalk of coagulation and inflammation and study contributions of inflammatory processes to the initiation of coagulation by tissue factor (TF). Our research also broadly addresses open question related to the roles of TF and coagulation protease signaling networks in the integration and modulation of inflammatory stimuli in immune cells. We are interested in the control of macrophage phenotypes by coagulation proteases and their receptors in chronic inflammation and use novel genetic mouse models that selectively delete or alter signaling specificity of components of the hemostatic system in innate immune cell populations. This genetic platform is employed in combination with transcriptional and proteomics approaches for generating fundamentally novel insights into cellular and molecular connections between coagulation and inflammation. We are interested in translational research that deciphers molecular mechanisms of diseases of the cardiovascular system and evaluates clinically relevant interventional proof-of-principle molecular probes in disease models.

Research Interests

  • Molecular mechanisms of prothrombotic activation of TF
  • Coagulation protease signaling in myelo-monocytic cells
