مستقبلات الدوبامين
The dopaminergic system has been implicated in a variety of disorders. Parkinson's disease results from loss of dopaminergic neurons in the striatum. Furthermore, most effective antipsychotics block D2 receptors, suggesting a role for dopamine in schizophrenia. Additional studies hypothesize dopamine dysregulation is involved in Huntington's disease, ADHD, Tourette's syndrome, major depression, manic depression, addiction, hypertension and kidney dysfunction. Dopamine receptor antagonists are used for some diseases such as schizophrenia, bipolar disorder, nausea and vomiting.
