Targeting of kinases to treat neurodegenerative diseases.

Neurodegenerative diseases, including Alzheimer, Parkinson, and multiple sclerosis, represent a growing global health crisis with limited therapeutic options that address disease progression. Protein kinases, which are crucial regulators of diverse cellular processes such as endolysosomal trafficking, neuroinflammation, and mitochondrial homeostasis, are frequently dysregulated in these conditions, making them attractive drug targets. This review explores the therapeutic potential of targeting key kinases implicated in neurodegeneration, specifically p38 MAPK, BTK, c-Abl/ABL1, CDK5, GSK3, JNK, LRRK2, and PINK1. We delve into their specific roles in disease pathophysiology, current therapeutic strategies, and the structural insights guiding our understanding of these kinases and the development of more selective inhibitors. Although significant challenges remain, particularly regarding selectivity and drug delivery to the brain, the advancements in our understanding of kinase biology and novel therapeutic modalities offer substantial promise for developing disease-modifying treatments. This review highlights the urgent need for continued research to identify new targets and translate these scientific breakthroughs into effective therapies for patients. SIGNIFICANCE STATEMENT: This review outlines the roles of protein kinases in neurodegenerative diseases and highlights emerging strategies for their therapeutic modulation. By integrating current knowledge of kinase signaling, drug development, and pharmacokinetics, this work provides a timely and practical framework to guide the development of disease-modifying treatments in an area of pressing clinical need.
