    Dopamine D1 and D2 receptors play distinct roles in pain regulation across key brain regions, influencing both sensory and emotional dimensions of pain.

  • 2

    In the prefrontal cortex, D1R is involved in pain signal integration, while D2R has a context-dependent regulatory role.

  • 3

    D1R in the nucleus accumbens mediates analgesic signals and pain-reward balance, whereas D2R modulates inflammatory and neuropathic pain.

  • 4

    Chronic pain may diminish D1R's tonic suppression in the anterior cingulate cortex, while D2R activation can suppress pain symptoms.

  • 5

    Targeting dopamine receptors presents a promising strategy for pain management, but challenges remain in achieving precise treatment.
