Project description

Antiphospholipid syndrome (APS) is a systemic autoimmune disease characterized by recurrent venous and/or arterial thrombosis or fetal loss associated with persistently elevated titers of antiphospholipid antibodies (aPLs). It has been known for over 20 years that aPL are causally involved in the pathogenesis of APS. However, the underlying signaling pathway is only partially understood.

I will focus on the characterization of the underlying cellular mechanisms. We could recently show that aPL activate an endosomal NADPH oxidase in different cell types. This increases the risk of thrombosis in patients. A detailed elucidation of the precise mechanisms by which aPL cause thrombosis promises a better understanding of APS pathogenesis and might provide new targets for the development of therapeutic strategies.

Research Interests

  • Pathogenesis of Antiphospholipid Syndrome
  • Activation and assembly of endosomal NADPH oxidase
  • Role of endosmal NADPH oxidase in innate immunity
  • Translocation of intracellular toll-like receptors

Research Funding



  • Antonia Köhler (Master Student)
  • Antje Canisius (MTA)
  • Carolin Orning (MTA)


Mentor of the Virchow-Fellow is Professor Karl J. Lackner, MD, Director of the Institute of Clinical Chemistry and Laboratory Medicine.
