process

neuron death

Comment Production of free radicals in the cells is significantly increased after 2h treatment with 6-OHDA. Besides the increase in intracellular oxidants, 6-OHDA also causes mitochondrial function impairment and DNA damage. Altogether, these events induce loss of mitochondrial potential, cytochrome c release and initiation of the apoptotic process.
