| Research Abstract |
Many neurodegenerative diseases are often caused due to abnormal formation of protein aggregates by transglutaminase 2 (TG2). Heparan sulfate proteoglycan (HSPG) has been also suggested to play critical role in many neurodegenerative diseases. Putative interaction of TG2 with HSPG has been suggested. The purpose of this study was to determine the role of HSPG species expressed by glial cells in cell-surface trafficking and biological activity of TG2 related to pathogenesis of neurodegeneration using an in vitro approach. Subcellular fractionation and immunocytochemical analyses showed that TG2-specific compartments were also specific for HSPGs suggesting possible interaction between those molecules. Understanding the bases of molecular interaction between TG2 and HSPGs and the precise role of HSPGs in regulation of biological activity of TG2 will help to identify the pathogenic mechanism of neurodegenerative diseases and to develop targeted rational therapy.
