Title	Murine Podocyte Membrane Proteomics
Description	Podocytes are essential cells of the renal blood filter. They structurally compose the renal blood filter by interdigitating with neighboring podocytes by the means of a modified adherens junction, the slit membrane. In podocyte injury, loss of podocytes is a common feature. Podocyte loss could be mediated by the cleavage of podocyte cell adhesion molecules through the A Disintegrin and Metalloproteinase 10 (ADAM10). Here we show that ADAM10 is highly abundant at the site of blood filtration, namely at podocyte foot processes. Podocyte-expressed ADAM10 is not required for the development of the renal filter but plays a major role in podocyte injury. Following antibody-mediated injury, ADAM10 is upregulated in humans and mice. ADAM10 activity results in the cleavage of cell-cell adhesion molecules. This cleavage paves the way for an activation of the injury related Wnt/-catenin signaling pathway and for podocyte loss. We therefore conclude that ADAM10-mediated ectodomain shedding of injury-related cadherins drives podocyte injury. As part of this project, we have analyzed the membrane proteome of murin podocytes to evaluate the abundance of membrane bound proteases.
