In affected glomeruli, proliferating podocytes adhere in aggregates to form glomerular pseudocrescents and fill an enlarged Bowman's space. Previously, we reported that sidekick-1 (sdk-1), an adhesion molecule of the immunoglobulin superfamily, was highly up-regulated in HIV-1 transgenic podocytes. In the current work, we explore how sdk-1 overexpression contributes to HIVAN pathogenesis. Murine podocytes infected with HIV-1 virus expressed significantly more sdk-1 than control-infected cells. Podocytes stably transfected with an sdk-1 expression construct grew in large aggregates with a simplified morphology characterized by a disorganized actin cytoskeleton, changes similar to podocytes in HIVAN. In contrast to controls, HIV-1 infected podocytes adhered to stably transfected sdk-1 podocyte aggregates in mixing studies. Furthermore, substrate-released cell sheets of wild-type podocytes were readily dissociated by mechanical stress, whereas HIV-1 podocytes remained in aggregates. The number of HIV-1 podocyte aggregates was significantly reduced in cells expressing a short hairpin RNA (shRNA) construct specific for sdk-1 compared with cells expressing control shRNA. Finally, in a HIVAN mouse model, sdk-1 protein was detected in podocytes in collapsed glomerular tufts and in glomerular pseudocrescents. These findings suggest that sdk-1 is an important mediator of cellular adhesion in HIV-infected podocytes and may contribute to podocyte clustering that is characteristic of pseudocrescent formation in HIVAN."xsd:string |
