Patients are frequently identified with PD only in the presence of tremor and other symptoms, by which time 6080% of the substantia nigra (SN) dopamine neurons have been lost, which occurs 5 to 15 years after the start of neuronal degeneration (Sulzer et al., 2018) (see Figure 1)

At the molecular level, the mechanism has been structurally resolved by NMR spectroscopy (Nature Communications, 2025): FOXO4-DRI binds to the disordered p53 TAD2 domain and forms a transiently folded complex through both the FOXO4-derived peptide region and its cationic cell permeability element
