Research focus
The Department focusses on the effects of matrix metalloproteases (MMPs) and A Disintegrin and Metalloprotease (ADAMs) and their inhibitors i.e. tissue inhibitors of metalloproteases (TIMPs) in the biology of CNS-inflammation, gliomas and ischemic disorders. A multitude of metalloproteases of both groups, MMPs and ADAMs, are upregulated in inflammatory disorders such as EAE and MS as well as in gliomas. The effects of metalloproteases are multifunctional: On one hand these factors play a pivotal role in tissue destruction by degrading the constituents of the extracellular matrix (ECM) and on the other hand MMPs and ADAMs can act as sheddases and thereby exert immunomodulatory and other signalling functions. The latter effects may be detrimental as well as beneficial for the diseased organ. We try to elucidate the role of particular proteases in the pathogenesis of EAE, CNS-ischemia and gliomas.
