| Research Abstract |
The cerebral ischemic preconditioning didn' t work in Caveolin-1 knockout mice and their cerebrovascular volume in the hippocampi was reduced. Their collateral formation of Willis ring was higher than WT mice, which might be a compensating mechanism. And in the hippocampi of young Caveolin-1 knockout mice, the synapse signaling components were reduced and neurodegenerative changes indicative Alzheimer's disease were seen, which are generally related to aging. Additionally, neuron-targeted Caveolin-1 re-expression in caveolin-1 knockout neurons in vitro decreased amyloid beta protein expression. These data suggests loss of cavolin-1 accelerates neurodegeneration and aging.
