abstract = {Podocytes, highly specialized epithelial cells, build the
outer part of the kidney filtration barrier and withstand
high mechanical forces through a complex network of cellular
protrusions. Here, we show that Arp2/3-dependent actin
polymerization controls actomyosin contractility and focal
adhesion maturation of podocyte protrusions and thereby
regulates formation, maintenance, and capacity to adapt to
mechanical requirements of the filtration barrier. We find
that N-WASP-Arp2/3 define the development of complex
arborized podocyte protrusions in vitro and in vivo. Loss of
dendritic actin networks results in a pronounced activation
of the actomyosin cytoskeleton and the generation of
over-maturated but less efficient adhesion, leading to
detachment of podocytes. Our data provide a model to explain
podocyte protrusion morphology and their mechanical
stability based on a tripartite relationship between actin
polymerization, contractility, and adhesion.},
