ReviewThe role of D2-autoreceptors in regulating dopamine neuron activity and transmission
چکیده انگلیسی


- D2-autoreceptors provide feedback inhibition that regulates the activity of the dopamine system.
- Axonal autoreceptors control the synthesis, release, and uptake of dopamine.
- Midbrain autoreceptors mediate transmission controlling dopamine neuron firing.
- This review summarizes the actions of D2-autoreceptors in regulating dopamine signaling.

Dopamine D2-autoreceptors play a key role in regulating the activity of dopamine neurons and control the synthesis, release and uptake of dopamine. These Gi/o-coupled inhibitory receptors play a major part in shaping dopamine transmission. Found at both somatodendritic and axonal sites, autoreceptors regulate the firing patterns of dopamine neurons and control the timing and amount of dopamine released from their terminals in target regions. Alterations in the expression and activity of autoreceptors are thought to contribute to Parkinson's disease as well as schizophrenia, drug addiction and attention-deficit hyperactivity disorder (ADHD), which emphasizes the importance of D2-autoreceptors in regulating the dopamine system. This review will summarize the cellular actions of dopamine autoreceptors and discuss recent advances that have furthered our understanding of the mechanisms by which D2-receptors control dopamine transmission.
