摘要

Sequestosome-1/p62, a key mediator in the clearance of damaged organelles and macromolecules during autophagy, serves as a marker of biological aging. We demonstrate elevated p62 in biopsied neuronal cells in patients with psychosis compared to healthy controls. In healthy controls, p62-indicated biological/autophagic age is positively correlated with chronological age over time, whereas in patients, neuronal p62-indicated biological/autophagic age shows no correlation with chronological age, being significantly higher than chronological age from the onset of the disease.
