Formation of the glomerular microvasculature is regulated by VEGFR-3.

ABSTRACT: Microvascular dysfunction is a key driver of kidney disease. Pathophysiological changes in the kidney vasculature are regulated by vascular endothelial growth factor receptors (VEGFRs), supporting them as potential therapeutic targets. The tyrosine kinase receptor VEGFR-3, encoded by FLT4 and activated by the ligands VEGF-C and VEGF-D, is best known for its role in lymphangiogenesis. Therapeutically targeting VEGFR-3 to modulate lymphangiogenesis has been proposed as a strategy to treat kidney disease. However, outside the lymphatics, VEGFR-3 is also expressed in blood vascular endothelial cells in several tissues including the kidney. Here, we show that Vegfr-3 is expressed in fenestrated microvascular beds within the developing and adult mouse kidney, which include the glom
