Intranasal Insulin Ameliorates Cerebral Hypometabolism, Neuronal Loss, and Astrogliosis in Streptozotocin-Induced Alzheimer’s Rat Model
Abstract Intracerebroventricular injection of streptozotocin (ICV-STZ) in rodents leads to cognitive impairments and several pathological changes like Alzheimer’s disease (AD). However, there is hardly any research about the effect of ICV-STZ on regional cerebral glucose metabolism in rodents. Previ...

| 520 | |a Abstract Intracerebroventricular injection of streptozotocin (ICV-STZ) in rodents leads to cognitive impairments and several pathological changes like Alzheimer’s disease (AD). However, there is hardly any research about the effect of ICV-STZ on regional cerebral glucose metabolism in rodents. Previous studies have demonstrated that intranasal insulin improves cognition in AD patients. However, the underlying mechanism remains elusive. Here, we treated the ICV-STZ rats with daily intranasal delivery of insulin (2 U/day) for 6 consecutive weeks, then monitored 18F-fluorodeoxyglucose (18F-FDG) uptake using a high-resolution small-animal positron emission tomography (microPET) and studied the expression of neuronal nuclei (NeuN) and glial fibrillary acidic protein (GFAP) using immunohistochemical staining. We observed that 18F-FDG uptake decreased significantly at the prefrontal cortex, cingulate cortex, striatum, hippocampus, and entorhinal cortex in ICV-STZ rats as compared with the control rats. Intranasal insulin restores the cerebral glucose metabolism in prefrontal and cingulate cortex and attenuates astroglia activation and neuronal loss in the hippocampus of ICV-STZ rats. These findings provide the mechanistic basis for treating AD patients with intranasal insulin. | ||

However, there is hardly any research about the effect of ICV-STZ on regional cerebral glucose metabolism in rodents. Previous studies have demonstrated that intranasal insulin improves cognition in AD patients. However, the underlying mechanism remains elusive. Here, we treated the ICV-STZ rats with daily intranasal delivery of insulin (2 U/day) for 6 consecutive weeks, then monitored 18F-fluorodeoxyglucose (18F-FDG) uptake using a high-resolution small-animal positron emission tomography (microPET) and studied the expression of neuronal nuclei (NeuN) and glial fibrillary acidic protein (GFAP) using immunohistochemical staining. We observed that 18F-FDG uptake decreased significantly at the prefrontal cortex, cingulate cortex, striatum, hippocampus, and entorhinal cortex in ICV-STZ rats as compared with the control rats. Intranasal insulin restores the cerebral glucose metabolism in prefrontal and cingulate cortex and attenuates astroglia activation and neuronal loss in the hippocampus of ICV-STZ rats.

However, there is hardly any research about the effect of ICV-STZ on regional cerebral glucose metabolism in rodents. Previous studies have demonstrated that intranasal insulin improves cognition in AD patients. However, the underlying mechanism remains elusive. Here, we treated the ICV-STZ rats with daily intranasal delivery of insulin (2 U/day) for 6 consecutive weeks, then monitored 18F-fluorodeoxyglucose (18F-FDG) uptake using a high-resolution small-animal positron emission tomography (microPET) and studied the expression of neuronal nuclei (NeuN) and glial fibrillary acidic protein (GFAP) using immunohistochemical staining. We observed that 18F-FDG uptake decreased significantly at the prefrontal cortex, cingulate cortex, striatum, hippocampus, and entorhinal cortex in ICV-STZ rats as compared with the control rats. Intranasal insulin restores the cerebral glucose metabolism in prefrontal and cingulate cortex and attenuates astroglia activation and neuronal loss in the hippocampus of ICV-STZ rats. These findings provide the mechanistic basis for treating AD patients with intranasal insulin.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Glucose metabolism</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Positron emission tomography</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Intranasal insulin</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Alzheimer’s disease</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Streptozotocin</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Guo, Zhangyu</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Mao, Yan-Fang</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Zheng, Tingting</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Zhang, Baorong</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Neurotoxicity research</subfield><subfield code="d">New York, NY : Springer, 1999</subfield><subfield code="g">33(2017), 4 vom: 19.

Intranasal Insulin Ameliorates Cerebral Hypometabolism, Neuronal Loss, and Astrogliosis in Streptozotocin-Induced Alzheimer’s Rat Model |
| abstract |
Abstract Intracerebroventricular injection of streptozotocin (ICV-STZ) in rodents leads to cognitive impairments and several pathological changes like Alzheimer’s disease (AD). However, there is hardly any research about the effect of ICV-STZ on regional cerebral glucose metabolism in rodents. Previous studies have demonstrated that intranasal insulin improves cognition in AD patients. However, the underlying mechanism remains elusive. Here, we treated the ICV-STZ rats with daily intranasal delivery of insulin (2 U/day) for 6 consecutive weeks, then monitored 18F-fluorodeoxyglucose (18F-FDG) uptake using a high-resolution small-animal positron emission tomography (microPET) and studied the expression of neuronal nuclei (NeuN) and glial fibrillary acidic protein (GFAP) using immunohistochemical staining. We observed that 18F-FDG uptake decreased significantly at the prefrontal cortex, cingulate cortex, striatum, hippocampus, and entorhinal cortex in ICV-STZ rats as compared with the control rats. Intranasal insulin restores the cerebral glucose metabolism in prefrontal and cingulate cortex and attenuates astroglia activation and neuronal loss in the hippocampus of ICV-STZ rats. These findings provide the mechanistic basis for treating AD patients with intranasal insulin. © Springer Science+Business Media, LLC 2017 |
