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 me...
