Abstract
Cilia are best known and most studied for their manifold functions enabling proper embryonic development. Loss of cilia or dysfunction thereof results in a great variety of congenital malformations and syndromes. However, there are also cilia-driven conditions, which manifest only later in life, such as polycystic kidney disease. Even degenerative diseases in the central nervous system have recently been linked to alterations in cilia biology. Surprisingly though, there is very little knowledge regarding cilia in normally aged organisms absent any disease. Here, it is provided evidence that cilia in naturally aged mice are considerably elongated in the kidney and pancreas, respectively. Moreover, such altered cilia appear to have become dysfunctional as indicated by changes in cellular signaling.
