Christian Schultz is a Professor in Neuroanatomy at the Medical Faculty Mannheim, part of Heidelberg University. His research focuses on axonal compartment plasticity, particularly the axon initial segment (AIS), and membrane contacts between organelles like peroxisomes and the endoplasmic reticulum (ER). He investigates how AIS structural changes impact neuronal excitability using in vivo models like the mouse whisker-to-barrel pathway. Recent studies revealed rapid AIS remodeling within hours of environmental enrichment. Future work includes live imaging of AIS dynamics and exploring peroxisome-ER interactions in neurodegeneration, especially retinal pathologies.
Key research areas include:
- Developmental mechanisms of axonal polarity
- Role of ACBD5-VAPB protein interactions in peroxisome-ER contacts
- Functional significance of axon-carrying dendrites in hippocampal ensembles
His lab employs advanced techniques such as live reporter mouse lines for in vivo imaging and genetic models to study neurodegenerative processes. Current projects aim to untangle AIS plasticity's role in sensory processing and elucidate how organelle membrane contacts influence neuronal health.
Notable findings include identifying ACBD5 as a critical mediator of peroxisome-ER contacts and demonstrating bidirectional AIS plasticity linked to homeostatic regulation of neuronal excitability.
