N2 - Soluble forms of oligomeric amyloid beta (AβO) are involved in the loss of synaptic plasticity and memory, especially in early phases of Alzheimer's disease. Stimulation of dopamine D1/D5 receptors (D1R/D5R) is known to increase surface expression of synaptic α-amino-3-hydroxyl-5-methyl-4-isoxazole-propionate subtype glutamate and N-methyl-D-aspartate subtype glutamate receptors and facilitates the induction of the late phase of long-term potentiation (LTP), probably via a related mechanism. In this study, we show that the D1/D5R agonist SKF38393 protects LTP of hippocampal CA1 synapses from the deleterious action of oligomeric amyloid beta. Unexpectedly, the D1R/D5R-mediated recovery of LTP is independent of protein kinase A or phospholipase C pathways. Instead, we found that the inhibition of Src-family tyrosine kinases completely abolished the protective effects of D1R/D5R stimulation in a cellular model of learning and memory.
