| Research Abstract |
Cerebral small-vessel disease is a common disorder in elderly populations; however, its molecular basis is not well understood. We recently demonstrated that mutations in the high-temperature requirement A (HTRA) serine peptidase 1 (HTRA1) gene cause a hereditary cerebral small-vessel disease, cerebral autosomal recessive arteriopathy with subcortical infarcts and leukoencephalopathy (CARASIL). HTRA1 belongs to the HTRA protein family, whose members have dual activities as chaperones and serine proteases and also repress transforming growth factor-beta (TGF-beta) family signaling. We investigated the molecular pathogenesis of CARASIL in HTRA1 null mouse. By immunohistochemical analysis we have found the alteration in cerebral small vessels in the model. This model mouse could be useful for the investigation of the pathogenesis of cerebral small vessel disease.
