Research Abstract |
We have identified Ephrin-B1 and SV2B as molecules of which dysfunction is involved in the development of nephrotic syndrome and neuronal and vascular diseases. In this study we analyzed the expression and function of these molecules with several experimental models and knockout mice. This study revealed that ephrin-B1 was localized at the surface of podocyte and bound to nephrin, a critical molecule of the slit diaphragm. SV2B (synaptic vesicle protein 2B), which is expressed on the surface of synaptic vesicles in neuron, was localized at the slit diaphragm area in podocyte and played an essential role in maintaining the structure of foot process, slit diaphragm and GBM. SV2B KO mice showed proteinuria. The altered expression of the slit diaphragm molecules including CD2AP and nephrin was detected in KO mice. These observations provide important information to understand the common pathogenesis of nephrotic syndrome and other diseases.
