Research Interest

Investigation of protein misassembly, misfolding or misprocessing in brain diseases, and the development of pharmacotherapies to interfer with or prevent these protein pathologies. There is a focus on neurobiology and proteinbiochemistry. Generation of (mis)assembled proteins is investigated at the levels of generation, recognition and degradation in in vivo and in vitro models.

Specific Projects
  1. Neurobiology of chronic mental diseases (CMD) schizophrenia and recurrent affective disorders:
Identification and characterization of CMD-associated proteins by proteomics, biochemistry, cell biology. Characterizing sporadic CMD as protein misassembly disorders. Translational research for identifying biological markers as diagnostic tests for CMD and CMD-associated conformers as pharmacological targets (Interview of International Innovation with Carsten Korth from July 2012 on Mental illness Research).
  2. Cell biology and functional regulation of protein misfolding:
Generation of conformation-sensitive ligands. Development of animal models for protein conformational disorders.
  3. Pharmacotherapy of protein conformational diseases.
  4. Neurobiology of Aging
Insoluble and aggregated protein deposits are not only hallmarks of neurodegenerative disorders but are also hallmarks of the aging brain in the form of acculumating lipofuscin and other cellular debris. Dysfunctional protein degradation in the aging post-mitotic cell is investigated by proteomic, biochemical and cell biological techniques. Cross-influences to protein conformatonal diseases are revealed.
