This was in line with other PD models in which mitochondrial respiration was seen to be increased including α-synuclein fibrils in neuroblastoma cells (Ugalde et al., 2020), lymphoblast cell lines made from idiopathic PD patients (iPD) (Annesley et al., 2016) and fibroblasts from iPD patients (Haylett et al., 2016). The gene discussed is SNCA; the disease is Parkinson disease.
