Determinants of metabolic switches and cell death of glomerular cells in Focal Segmental Glomerulosclerosis and Ageing.
Glomerular diseases (GD) encompass a broad array of clinicopathologically defined syndromes which together account for 90% of end-stage kidney disease costing € 16 billion per annum to treat in the EU alone. Recent insights have defined the central role of the podocyte as both the regulator of glomerular development as well as the determinant of progression to glomerulosclerosis and renal failure. We are numbering the GPCRs in normal and diseased podocytes and established that EGFR is transactivated by Gq-coupled GPCRs in these cells. We shall determine whether behavior of these cells is influenced by activation of the identified receptors in vitro. In GD, podocytes may undergo detachment, apoptosis, proliferation or migration. Using podocytes from glomerular explants, we will address the effects of GPCR agonists on in vitro models of each of these changes.
We will study the extracellular stimuli that elicit pathological changes in autophagosome Golgi/ER crosstalk in podocytes. This research axis synergize with research performed by Dr. Jörn Dengjel.
We will investigate mechanisms promoting podocyte aging and death. Autophagy is blocked in an age dependent manner by unknown mechanisms. Our data suggest that some GPCRs contribute to this phenomenon. Interaction with cellular respiration is suggested by our preliminary findings. This will be optimally studied with Pr. Tobias Huber Lab.
At last, we will study genomic and miRNA signature of podocytes from young and ageing mice with common co-morbid conditions such as hypertension and diabetes.
