Gröne lab

The Gröne lab studies the cellular and molecular processes of dedifferentiation, regeneration and atrophy of polarized cells, specifically renal tubular epithelia. The kidney expresses a complex array of epithelia with different morphology and function.

There are currently two major topics:

1: The role of glycosphingolipids, complex membrane lipids and part of lipid microdomains, in modulation of location and activity of membrane proteins (e.g. receptor kinases membrane transporters)

 2: The role of lipid-dependent transcription factors (e.g. Wnt pathway, nuclear receptors) in steering homeostasis and pathophysiologic reactions of polarized epithelia.

 

 In addition the group can take recourse to a large archive of human renal biopsies for translational studies.

We also have a consultative reporting on histology of human or animal tissue; transmission electron microscopy analysis is offered.
