Cytotoxicity Models in Chromaffin Cells to Evaluate Neuroprotective Compounds

Primary cultures of bovine chromaffin cells are considered a good model to evaluate potential neuroprotective compounds for two major reasons: (i) they share many common features to neurons as they synthesize, store, and release neurotransmitters; they are excitable cells that express voltage-dependent calcium, potassium, and sodium channels; they express different neuronal receptor subtypes; and (ii) they can be easily cultured in high quantities from adult animals; as adult para-neurons, they can be used to reproduce different neurodegenerative-like cytotoxicity models. In this chapter, we describe protocols to mimic calcium overload (veratridine and thapsigargin) and oxidative stress (rotenone plus oligomycin-A and 6-hydroxydopamine) to evaluate potential neuroprotective compounds.
