Research focus

Growth Factor Receptor Signaling and Biology in Nervous System Development and Metabolic Regulation

With a focus on growth factor receptor signaling, we investigate different aspects of nervous system development and metabolic regulation. Currently, our studies center on three different ligand/receptor systems:

  • p75 neurotrophin receptor and neurotrophin family ligands
  • GFRα1, Ret and NCAM receptors and GDNF family ligands
  • TGF-β superfamily receptors ALK7 and ALK4 and their ligands Activins and GDFs.

Using these signaling systems as entry points, our goal is to discover novel, general biological principles of broad importance for nervous system development and metabolic functions.

Current topics of investigation include:

• Mechanism of p75NTR death receptor activation and downstream signal propagagation
• Role of GDNF family signaling in nervous system development 
• Mechanisms underlying the development and differentiation of cortical GABAergic interneurons
• Activin receptor signaling in pancreatic beta-cell function and adipose tissue homeostasis
• A chemical-genetic approach to study activin receptor signaling in metabolic regulation
