Abstract
Alzheimer's disease (AD) is the most common neurodegenerative disease in clinical practice. The kynurenine pathway (KP) is a potential intersection of factors associated with the development of AD (central nervous inflammation, glutamate excitotoxicity, and tau phosphorylation, among others). Pharmacological modulators targeting KP enzymes, such as inhibitors or agonists, and their major neuroprotective metabolites are beneficial in alleviating AD progression. Exercise significantly improves AD symptoms and also impacts KP pharmacokinetics. Promoting the production of neuroprotective active metabolites by KP may be one of the central mechanisms by which exercise improves AD symptoms. This article reviews the possible role of KP in AD neurodegeneration and AD exercise prevention and treatment.
