Autophagy, 1-17 (2021-06-08)
Olfactory dysfunction, one of the earliest non-motor symptoms of Parkinson disease (PD), is accompanied by abnormal deposition of SNCA/α-synuclein in the olfactory bulb (OB). The macroautophagy/autophagy-lysosome pathway (ALP) plays an important role in degrading pathological SNCA and modulating this pathway...
