A 2020 publication in the MDPI journal, Biomolecules looks at targeting a-syn for PD therapeutics. PD is characterized by the loss of dopaminergic neurons in the substantia nigra and the presence of Lewy Bodies (cytoplasmic inclusions). The Lewy Bodies are clumps of protein that can build up and create problems in the brain. The Lewy Bodies contain the aggregated a-synuclein protein that can propagate throughout the brain. Many PD studies have looked at ways of inhibiting a-synuclein accumulation to ease PD symptoms. There are various approaches to a-syn inhibition and multiple clinical trials that examine the link between PD and a-syn, with the hope that a treatment may be found for PD using a-syn. Given the central role of α-syn in PD pathology and progression, α-syn met the criteria to be a tantalizing and evident therapeutic target for PD. Promising strategies include predominantly immunization, anti-aggregative molecules, and an increase in α-syn clearance.
