| Research Abstract |
There are two types of cells in the brain ; the neuronal cell and glial cell. Extracellular matrix (ECM), such as hyaluronan and proteoglycan, exists in extracellular region of these cells. There are two dense organized ECM in the brain, one is in the perineuronal net (PNN) and other is at the node of Ranvier. The PNN is a mesh like structure surrounding the neuronal cell. Bral2 forms ECM complex with hyaluronan and proteoglycan, and is localized in the PNN of the auditory system. In this study, it is strongly suggested that Brals play key roles in the ECM assembly and the complex is essential for the neuronal activity through the analysis of Bral - deficient mice
