| Research Abstract |
The Australian laboratory which I investigated before cloned the insulin-regulated aminopeptidase (IRAP) as a receptor for angiotensin IV, sub-component of renin-angiotensin system. It is a member of the family of zinc- dependent membrane aminopeptidases, which is mainly located in hippocampus and plays an important role for translocation to membrane of GLUT4. We reported another sub-component, angiotensin (1-7) improved glucose intolerance via increased MEF1 and GLUT4 production. We planned angiotensin IV and IRAP as a new therapeutic target for cognitive impairment using amyloid beta 1-40 intra-ventricular infusion model with IRAP knockout mice donated from the Australian laboratory. The cognitive function of this model is too unstable to evaluate angiotensin IV and IRAP function for cognitive impairment, we are now planning to make double knockout mice with IRAP and APP.
