Group PD Dr. Markus Schwab - Molecular Regulation of Neural Networks

​​​Research

The nervous system is an intricate network of neurons and glia cells. The goal of our research is to investigate molecular mechanisms that regulate neuron-glia interactions and orchestrate the development and adult functions of neural networks in the peripheral and central nervous system. Furthermore, we aim at a better understanding of pathological processes that compromise cellular communication and thereby promote the pathogenesis of neurological disorders, such as multiple sclerosis and schizophrenia.

We interrogate these processes by applying state-of-the-art molecular, biochemical, and histological approaches in genetically modified mice that permit spatially and temporally controlled genetic interventions. Our research is focused on a family of neural growth factors, the neuregulins (NRG), and their tyrosine kinase receptors from the ErbB family. These proteins are important regulators of neural migration, axonal pathfinding and myelination during development. In addition, NRG/ErbB signaling has been implicated in the modulation of synaptic functions and neuronal excitability in glutamatergic and GABAergic networks, and thereby may contribute to plasticity processes linked to learning and memory in the adult brain.
