| Research Abstract |
Inflammation might be involved in the molecular link between Alzheimer' s disease and diabetes mellitus. We showed that the increase in brain inflammatory cytokine(interleukin-6) level was significantly higher in Alzheimer APP-Tg than in WT mice after peripheral LPS injection. Blood-brain barrier(BBB) became more permeable in APP-Tg mice during peripherally evoked inflammation, suggesting the increased vulnerability of BBB to inflammation in this animal model of AD. These findings might support the hypothesis that inflammation is involved in the molecular link between Alzheimer' s disease and diabetes mellitus.
