Abstract:

Alzheimer's disease (AD) is the leading cause of age-related dementia, which is characterized by progressive brain atrophy and cognitive dysfunction, ultimately leading to an inability to care for oneself. Although some pharmacologic treatments may alleviate AD symptoms, they do not halt the progression of AD and have multiple side effects. Based on the hypothesis that there are multiple pathogenic mechanisms in AD, and the progression of AD is affected by more than a single condition. Recently, the oxidative stress microenvironment in the brain has attracted much attention. Mesenchymal stem cells (MSCs) improve the microenvironment of the brain due to their multiple regulatory roles, such as immune regulation, anti-inflammation, regeneration, antioxidant, anti-apoptosis, and neuroprotection, which reduce pathological changes of AD and thus reduce its effects. MSCs, especially dental pulp stem cells (DPSCs) , not only secrete neuroprotective and anti- inflammatory factors to promote neuronal survival but also promote the accumulation of microglia around protein aggregates, remove pathological aggregates, and alleviate mitochondrial damage. This review focuses on using MSCs and potential MSCs cellular resources DPSCs to slow down AD development by improving the oxidative stress microenvironment, providing new ideas for treating AD in the clinic.

Key words: Alzheimer's disease, Mesenchymal stem cells, Dental pulp stem cells, Oxidative stress, Reactive oxygen species
