Regulation of ciliary trafficking of polycystin-2 and the pathogenesis of autosomal dominant polycystic kidney disease

Autosomal dominant human hereditary disorder characteristi polycystic kidney disease （ADPKD） is one of the most common c of develop cumulated evidence has suggested that primary cili ment of bilateral multiple fluid-filled kidney cysts. Acum of renal epithelial cell plays a key role in cystogenesis. In this article we will give an overview on the basic information about polycystic kidney disease （PKD） and summarize the recent progresses in studies of regulation of polycystin-1 and -2 trafficking to cilia. We will also discuss the possible role of trafficking defects of polycystins on the pathogenesis of ADPKD.
