Abstract:
:Dopamine (DA) is a neurotransmitter implicated in multiple functions, including movement, cognition, motivation, and reward. The DA transporter (DAT) is responsible for clearing extracellular DA, thereby terminating DA neurotransmission. Previously, it has been shown that insulin signaling through protein kinase B/Akt regulates DAT function by fine-tuning DAT cell surface expression. Importantly, specific Akt isoforms (e.g., Akt1, Akt2) serve distinct physiological functions. Here, we demonstrate using isoform-specific Akt inhibitors that basal activity of Akt2, rather than Akt1, regulates DAT cell surface expression. Since Akt2 activation is mediated by insulin, these data further implicate insulin signaling as an important modulator of DAT function and dopaminergic tone.

信件abstract::Parkinson's disease (PD) has long been seen as a disorder caused by degeneration of the dopaminergic system, leading to the classic motor manifestations of the disease. However, there is now overwhelming evidence that PD is more than a disease merely caused by dopamine depletion. It is well-known that a myriad of othe...
