Research Topic

We are interested in the development and function of Drosophila glial cells. The nervous system comprises six different glial cells types. Within the nervous system several distinct cell types guarantee its functionality. The wrapping glia forms membrane ensheathment around axons in the peripheral nervous system, which resemble the differentiation of vertebrate Schwann cells.  Within this CRC we ask how glial cells can recognize axonal bundles and how they can establish the axonal ensheathment employing advance Drosophila genetics, imaging and biochemistry. Two other glial cell types establish the blood-brain barrier.  We address how this barrier is established and stays intact in the growing organism and we analyze how transport of nutrients is organized across this barrier.  Finally, glial cells such as the ensheathing glia and the astrocyte-like glial cells are able to modulate synaptic function.  We study these properties by using advanced larval tracking hard- and software ( that had been established in the lab.

CRC1348 Retreat 2019 Oberwerries

CRC 1348 Retreat 2019 Oberwerries

The CRC has staged a successful and productive annual retreat at the Landesturnschule Oberwerries with lots of mental and some physical exercise. We are due to return fully equipped with sweat pants, trainers and shower gel in 2020!
