PhD position (m/f) in biology - EphB/ephrinB in stroke (Heidelberg, Germany)

The Institute of Physiology and Pathophysiology of Heidelberg University, Working Group Neurovascular Research (Prof. Dr. Hugo H. Marti) offers a
PhD position
to study the impact of the EphB/ephrinB system on inflammation and edema formation during cerebral ischemia.
Stroke is one of the most relevant causes of death in the western world and responsible for 6 billion euro economic costs caused by illness in Germany annually. As the pathophysiological and regenerative mechanisms of this disease are only partially understood, no causative therapy dealing with the consequences of the ischemic insult is available. In this context, the role of the Eph/ephrin-receptor/ligand-system has not been investigated so far although it decisively controls genesis, architecture and function of the brain. This proposal is ought to investigate as to how the EphB/ephrinB-system regulates the function of endothelial and immune cells under these circumstances. Consequently, the working program is specifically focused on the analysis of (i) the relevance of ephrinB1/B2 for the function of the blood-brain-barrier with respect to the formation of brain edema as well as the transmigration of leukocytes (monocytes, granulocytes) and (ii) the ischemia-related activation of leukocytes and resident immune cells (microglia, astroglia) by the EphB/ephrinB-system.
Group and Working Environment:
This is a German Research Foundation-funded joint research project of Prof. H.H. Marti (WG Neurovascular Research) and Prof. T. Korff, both affiliated with the Division of Cardiovascular Physiology (director: Prof. M. Hecker) at the Institute of Physiology and Pathophysiology. The division comprises 6 principal investigators, 5 postdocs and about 20 PhD and MD students from various countries.
Heidelberg, home to Germany’s oldest university and one of the premier centres of biomedical research in Europe, provides ample opportunity for scientific exchange not only within the university, but with other renowned research institutions as well.
