Cell proliferation and neurogenesis alterations in Alzheimer's disease and diabetes mellitus mixed murine models.

The classic neuropathological features of Alzheimer's disease (AD) are accompanied by other complications, including alterations in adult cell proliferation and neurogenesis. Moreover recent studies have shown that traditional markers of the neurogenic process, such as doublecortin (DCX), may also be expressed in CD8 T cells and ionized calcium-binding adaptor molecule 1 (Iba1 ) microglia, in the close proximity to senile plaques, increasing the complexity of the condition. Altered glucose tolerance, observed in metabolic alteratioins, may accelerate the neurodegenerative process and interfere with normal adult cell proliferation and neurogenesis.
