ABSTRACT

ABSTRACT Autophagy is a crucial cellular process responsible for the degradation and recycling of damaged or unnecessary components, maintaining cellular homeostasis and protecting against stress. Dysregulation of autophagy has been implicated in a variety of neurodegenerative diseases, including multiple sclerosis, Alzheimer’s disease, Parkinson’s disease, amyotrophic lateral sclerosis, and Huntington’s disease. Various types of autophagy exist, each with distinct mechanisms, such as macroautophagy, mitophagy, lipophagy, and chaperone-mediated autophagy. These processes are essential for the removal of toxic substrates like protein aggregates and dysfunctional mitochondria, which are vital for neuronal health. In neurodegenerative diseases, the impairment of these clearance mechanisms leads to the accumulation of harmful substances, which accelerate disease progression. Modulating autophagy has emerged as a promising therapeutic strategy, with ongoing studies investigating molecules that can either stimulate or regulate this process. However, despite its potential, significant challenges remain in translating preclinical findings into clinically effective treatments. In this review, we will explore the different types of autophagy, their roles in neurodegenerative diseases, and the therapeutic potential associated with modulating these processes.
