Research

The Sendtner Lab is investigating the roles of Brain-derived neurotrophic factor (BDNF) and Ciliary neurotrophic factor (CNTF), both essential regulators of neural plasticity. They are interested in how these factors and their receptors modulate the axonal cytoskeleton and presynaptic function in motoneurons and modulate circuits for movements and higher brain functions in the hippocampus, striatum and cerebral cortex. In motoneurons local synthesis of new proteins can take place in axons and axon terminals. The lab is interested in identifying ribosomal structures and mechanisms for local axonal protein synthesis, using 3D Electron Tomography analyses coupled with advanced immune-light microscopy. Further, they study signaling pathways that affect actin dynamics in axons, dendrites and also the nucleus of motoneurons. Another focus i.a. is axonal autophagy. As dysregulation of autophagy can contribute to neurodegeneration, they are interested in the molecular signaling mechanisms that direct synaptic vesicles and components of presynaptic active zones into autophagy, and how these mechanisms contribute to synaptic plasticity and functional maintenance at neuromuscular endplates and other types of synapses.
