Abstract: Millions of people are suffering from Alzheimer’s disease globally, but there is still no effective treatment for this neurodegenerative disease. Thus, novel therapeutic approaches for Alzheimer’s disease are needed, which requires further evaluation of the regulatory mechanisms of protein aggregate degradation. Lysosomes are crucial degradative organelles that maintain cellular homeostasis. Transcription factor EB-mediated lysosome biogenesis enhances autolysosome-dependent degradation, which subsequently alleviates neurodegenerative diseases, including Alzheimer’s disease, Parkinson’s disease, and Huntington’s disease. In this review, we start by describing the key features of lysosomes, including their roles in nutrient sensing and degradation, and their functional impairments in different neurodegenerative diseases. We also explain the mechanisms — especially the post-translational modifications — which impact transcription factor EB and regulate lysosome biogenesis. Next, we discuss strategies for promoting the degradation of toxic protein aggregates. We describe Proteolysis-Targeting Chimera and related technologies for the targeted degradation of specific proteins. We also introduce a group of LYsosome-Enhancing Compounds, which promote transcription factor EB-mediated lysosome biogenesis and improve learning, memory, and cognitive function in APP-PSEN1 mice. In summary, this review highlights the key aspects of lysosome biology, the mechanisms of transcription factor EB activation and lysosome biogenesis, and the promising strategies which are emerging to alleviate the pathogenesis of neurodegenerative diseases.
