"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…·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.

Plasma Membrane Calcium Atpase downregulation in dopaminergic neurons alters cellular physiology and behavior in Drosophila melanogaster

Brenda Erhardt, María Celeste Leal, María Silvina Marcora…·Fernando Juan Pitossi

This study downregulates PMCA in dopaminergic neurons of Drosophila to model Parkinson's Disease, finding increased calcium, oxidative stress, locomotor changes, and lifespan reduction.
