PINK1 (PTEN-induced kinase 1) neurons are dopaminergic neurons in the substantia nigra pars compacta that selectively degenerate in Parkinson's disease due to mutations in the PINK1 gene. These neurons are critical for understanding autosomal recessive familial PD and the role of mitochondrial quality control in neuronal survival[1].

The PINK1 gene (PARK6) encodes a serine/threonine-protein kinase that localizes to mitochondria. It plays a crucial role in mitophagy — the selective autophagy of damaged mitochondria[2].
The study of Tau Associated Neurons has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.
