| abstractText | Alzheimer's disease (AD) in the elderly is frequently accompanied by chronic cerebral hypoperfusion (CCH), which impairs the clearance of amyloid beta (Abeta) due to the dysfunction of the blood-brain barrier (BBB) and accelerates the AD pathology. Since the coagulation and complement cascades are associated with BBB dysfunction and AD pathology, we investigated the expression changes of coagulation (fibrinogen alpha chain-FGA, coagulation factor XIII A chain-Factor XIIIalpha) and complement (plasma protease C1 inhibitor-C1-INH, Complement component 3-C3) factors in the brain of novel AD model (APP23) mice with CCH at 12months of age. Immunohistochemical and immunofluorescent analysis showed that the expressions of FGA, Factor XIIIalpha, C1-INH and C3 were significantly increased in cerebral neocortex, hippocampus, and thalamus of APP23+CCH group (n=12) as compared with wild type (WT, n=10) and APP23 (n=10) groups (()P<.05 and ()P<.01 vs WT; (#)P<.05 and (##)P<.01 vs APP23), especially near and inside of neurovascular unit. The present study suggests that CCH activated both the coagulation and complement cascades in a novel AD model mice brain accompanied by the acceleration of AD pathology. |
