Comparative proteomic analysis of microvescicoles and exosomes isolated from urine of medullary sponge kidney disease (MSK) versus Autosomal dominant polycystic kidney disease (ADPKD) patients.

Microvescicles (MV) and exosomes (EX) seem to be involved in the pathogenetic machinery of the autosomal dominant polycystic kidney disease (ADPKD), but, at the moment, no studies have assessed their role in medullary sponge kidney disease (MSK), a sporadic kidney malformation featuring cysts, nephrocalcinosis and recurrent renal stones. To discover their role in this disease we employed a proteomic-based research strategy.
