| Outline of Final Research Achievements |
Podocyte is a cell that forms a glomerular filter for protein filtration. For the formation and the function of the glomerular filter, the cytoskeleton of podocyte needs to be appropriately regulated. However, it is poorly understood how cytoskeletons are regulated in podocyte. In this study, we aimed to elucidate regulatory mechanisms involved in the cytoskeletal regulation using two types of podocyte cell lines, Mouse Podocyte (MPC), and Human Podocyte (HPC). We found that dynamin 1 regulates microtubules, whereas dynamin 2 regulates actin cytoskeleton. Furthermore, we found that expression of dynamin 2 mutation found in Charcot Marie Tooth disease, a neurodegenerative disease, leads to aberrant actin cytoskeleton. These results strongly suggest that dynamin plays an essential role in the regulation of cytoskeleton in podocyte.
