Alzheimer's disease (AD) is the most common type of dementia in elderly people. The main pathological changes include extracellular Aβ protein deposition, formation of senile plaques (SPs), neuronal loss and intracellular neurofibrillary tangles (NFTs). 3xTg-AD mice have been widely used in AD research as the first kind of animal model which can generate both amyloid plaques and neurofibrillary tangles. This paper aims at summarizing the pharmacological research related with 3xTg-AD mice, including basic introduction of 3xTg-AD mice and pharmacological studies of many kinds of drugs on the mice.
