Main Field(s) of Research, Abstract
The main field of our research is the influence of sphigolipid metabolism on cellular signalling and apoptosis. Ceramides and metabolites thereof are ubiquitous constituents of membrane lipids in mammalian cells and involved in various cellular events like apoptosis, signal transduction and membrane trafficking. A dysfunctuion of the ceramide pathway is the cause for various deseases like HSN1 or Fabry. In our research we investigate the role of de novo sphingolipid synthesis on peripheral neuronal development and axonal regeneration as well as its possible influence in other neurodegenerative diseases like diabetic sensory neuropathy (DSN) or Alzheimer desease. Currently the main focus of our work is the function and regulation of the serine-palmitoyltransferase, a keyenzyme in the de-novo synthesis pathway of sphingolipids.
