Abstract:: Alpha-synuclein (α-syn) is a crucial protein involved in the pathogenesis of Parkinson’s Disease (PD) and other synucleinopathies. It is important with respect to neuron health, regulation of α-syn protein synthesis, and its degradation. Numerous cellular pathways implicated in the process of autophagy, chaperone, and proteolysis play a vital role in the maintenance of α-syn protein homeostasis. Autophagy dysfunction defeats α-syn protein accumulation and neuroinflammation, as present in dementia with Lewy bodies and sporadic PD. Oxidative stress is another key factor that intensifies α-syn protein misfolding and aggregation, thereby leading to neurodegeneration. Involvement in the treatment of α-syn related disorders includes passive and active immunization, inhibitors of protein aggregation, gene silencing technology, modulators of synaptic function, and target drug delivery systems. Other α-syn related therapy approaches include the development of a novel herbal formulation focusing on the gut-brain axis and interventions designed to enhance protein quality control. As clinical trials move forward, minimizing challenges related to the target involved, biomarkers, and patient stratification is crucial to decoding these therapies into effective management. These insights not only advance our understanding of α-syn biology but also highlight the urgency of early and multi-targeted therapeutic interventions.
