Tóm tắt

Neuronal degeneration, observed in the goldfish retina after MPTP administration, displays features of apoptosis, a physiological mechanism of cell death that occurs during development. The ultrastructural features of degenerating retinal neurons, that are seen in the inner nuclear layer two days after intravitreal MPTP administration, are consistent with classic changes observed in the programmed cell death. The DNA strand breaks that characterize apoptotic death are in situ detected by terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick-end labeling.
