Abstract
The role of dynamin in regulation of kidney filtration barrier is well documented. Dynamin binds to and produces filamentous actin, which is a key component of healthy podocyte foot processes (FPs). Destruction of dynamin, for example by cathepsin L, leads to loss of a functional actin network and uncoordinated membrane signaling, a situation that allows for effacement of FPs and proteinuria. Now, Khalil et al have examined the dynamin expression in kidneys of proteinuric animal models as well as in kidney patients and produced data that further clarifies the role of dynamin in glomerular and tubular proteinuria and may aid in pinpointing patients who are affected by loss of dynamin function and may benefit from appropriate therapeutic approaches.
