Beyond expectations: investigating nilotinib's potential in attenuating neurodegeneration in alzheimer's disease.

Neurodegenerative diseases, such as Alzheimer's disease (AD), pose a formidable global challenge. While therapeutic options are available, their limitations are significant, necessitating the development of innovative treatment approaches. Here, we highlight the importance of repurposing drugs and discuss the future of drug treatments for AD. We review the potential of tyrosine kinase inhibitors (TKI) for mitigating AD pathology and symptoms, as well as neurodegenerative processes more broadly. We focus on nilotinib, a selective BCR-ABL tyrosine kinase inhibitor, which has unique mechanisms of action involving the modulation of cell responses and removal of toxic proteins associated with AD pathogenesis. Encouraging studies have demonstrated its efficacy, calling for further investigation through clinical trials to assess its potential in various neurodegenerative conditions. However, despite these promising preclinical findings, no clinical studies have yet conclusively demonstrated its efficacy in treating AD. Considering the future directions in AD research, personalized medicine approaches hold promise by incorporating patient-specific factors, including sex and gender differences, to tailor nilotinib treatment for improved efficacy and safety profiles.
