ABSTRACT
Objective Through the observation on the distribution of hyperphosphorylated Tau,to investigate the connection between hyperphosphorylated Tau and learning, memory tasks. Furthermore, the treatment of App17 on brain tissues of diabetic mice. Methods Diabetic model mouse was produced in the use of streptozotion and App17 peptide as a curative was injected subcutaneously. Four weeks later, removed the brains. Immunohistochemical stainning was done with AT\|8, Tau\|1, again with Tau\|1 antibody after dephosphorylation. Results In the brains of diabetic mice positive AT\|8 reacting neurons were widely distribution in retrosplenial granular cortex, hippocampas, thalamus et al, the cytoplasm was darkly stained, while in normal mice and App17 peptide\|treated diabetic mice positive cells were localized in retrosplenial granular cortex, however, in hippocampas and RSG area, the cytoplasm were poorly stained. Conclusion Hyperphosphorylated Tau is widely expressed in brains of diabetic mice. App17 peptide can improve the hyperphosphorylated Tau in brains of diabetic mice, therefore, it may improve learning ability and memory.\;
