Beyond neurons: How does dopamine signaling impact astrocytic functions and pathophysiology?

Astrocytic dopamine receptor activation may play dual inflammatory roles in the central nervous system.

• Astrocytes are crucial regulators of brain health and influence synaptic signaling and plasticity.
• Dopamine significantly affects astrocytic function, suggesting an active role in astrocyte physiology.
• Astrocytic dopamine receptors are expressed in specific brain regions and affect neuroinflammation and synaptic regulation.
• Activation of these receptors can lead to both anti-inflammatory and pro-inflammatory responses, depending on the subtype and environment.
• Release of gliotransmitters and neurotrophins by astrocytes impacts communication with neurons, influencing synaptic plasticity and survival.
• Dysfunction in astrocytic dopaminergic signaling may contribute to neurodegenerative diseases, like Parkinson's disease.
