"Plasma Membrane Calcium ATPase Downregulation in Dopaminergic Neurons Induces Presynaptic Dysfunction and Neuronal Vulnerability In Vivo and In Vitro"

Brenda Erhardt, Valentina Koltyk, Mauricio Ricardo Bruno Dellepiane, Fernando Juan Pitossi, María Celeste Leal

This study shows that PMCA downregulation in dopaminergic neurons causes calcium dysregulation, presynaptic dysfunction, and increased neuronal vulnerability in Drosophila without overt neurodegeneration.
