The lab of Clinical Pathobiochemistry is headed by Prof. Steffens and focuses on two main topics:


  • Lipid signaling in cardiovascular disease (PI Steffens)

  • G-protein-coupled receptor signaling (PI Faussner)


Lipid signaling in cardiovascular disease

The endocannabinoid system has recently evolved as an endogenous lipid signaling system that is activated in a multitude of disorders, including atherosclerosis. This system comprises at least two distinct membrane receptors, CB1 and CB2, their endogenous ligands (named endocannabinoids) as well as enzymes for ligand biosynthesis and inactivation. Tissue and circulating levels of endocannabinoids and fatty acid amide analogues are dysregulated in atherosclerosis and its related cardiovascular risk factors, obesity, dyslipidemia, diabetes and endothelial dysfunction. However, the pathophysiological effect of this dysregulated tone in cardiovascular disease is not well understood. Our group aims to clarify the precise pathophysiological relevance of its receptors and ligands in cardiovascular disease.
