Significant decreases in protein levels of dynamin I, AP180, and synaptophysin were observed in both AD patients and mice with AβPPSWE as compared to controls.
Effects of homologous peptides HLDF-6 and PEDF-6 on behavior of animals with experimental Alzheimer's disease induced by chronic intracerebroventricular administration of beta-amyloid peptide Abeta(25-35) were studied in the zoosocial recognition test and Morris water maze.
This study aimed to evaluate the effect of 5-week treadmill training, in the icv-SZT model of sporadic AD, on cognitive function, oxidative stress (particularly mediated by NO) and on the astrocyte marker proteins, glial fibrillary acidic protein (GFAP) and S100B.
Treadmill exercise alleviates impairment of spatial learning ability through enhancing cell proliferation in the streptozotocin-induced Alzheimer's disease rats.
We suggest that NPY, perhaps acting via NPY Y1 receptors, might interact with the endogenous cholinergic system and play a role in improving the learning and memory processes in the rats with AD-like condition.
This evidence reveals that IBU-LA administration has the capability to maintain a high Ngb level allowing Ngb to perform a neuroprotective and antiapoptotic role, representing a valid tool in the therapeutic strategy of AD progression.
Reduction of hippocampal apoptosis by intracerebroventricular administration of extracellular signal-regulated protein kinase and/or p38 inhibitors in amyloid beta rat model of Alzheimer's disease: involvement of nuclear-related factor-2 and nuclear factor-κB.
After 28-day administration of NEK and piracetam, the abilities of learning and memory of AD rats in piracetam and low-dose, medium-dose and high-dose NEK groups were significantly improved as compared with the untreated group (P<0.01 or P<0.05); the expression of Abeta(1-42) in hippocampal tissues was decreased (P<0.01 or P<0.05) and the expression of NEP was increased (P<0.01 or P<0.05), especially in the high-dose NEK group.
Antioxidative and Neuroprotective Effects of Curcumin in an Alzheimer's Disease Rat Model Co-Treated with Intracerebroventricular Streptozotocin and Subcutaneous D-Galactose.
PHF-1: in CA2: 0.386 +/- 0.034 vs. 0.139 +/- 0.010, 0.193 +/- 0.041; in frontal cortex: 0.395 +/- 0.050 vs. 0.159 +/- 0.030, 0.190 +/- 0.044, respectively, P < 0.01); the number of GSK-3beta mRNA and P(38)MAPK mRNA positive cells of the AD model group, as well as the OD values, also increased significantly in the cortexes, hippocampus (GSK-3beta-mRNA: in CA2: 0.384 +/- 0.012 vs. 0.190 +/- 0.015, 0.258 +/- 0.064; in frontal cortex: 0.398 +/- 0.018 vs. 0.184 +/- 0.031, 0.218 +/- 0.049.
Effect of Linguizhugan decoction on neuroinflammation and expression disorder of the amyloid β‑related transporters RAGE and LRP‑1 in a rat model of Alzheimer's disease.
