AGTR1 and Parkinson disease: They identified a distinct subpopulation of DA neurons characterized by SRY‐box transcription factor 6 (Sox6) and angiotensin II receptor type 1 (AGTR1), which shows heightened susceptibility to degeneration in PD.[3] Notably, the deletion of Sox6 led to a decrease in SNpc markers and an increase in markers commonly linked to the ventral tegmental area (VTA).
