Altered muscarinic and nicotinic receptor densities in cortical and subcortical brain regions in Parkinson's disease.

abstract：:This study investigated possible D1/D2 interactions in rat and bovine striatal tissue by examining the effects of D2 antagonists on the action of dopamine at D1 dopamine receptors. In addition, the extent to which D2 antagonists may induce an agonist low-affinity state of the D1 receptor was evaluated in comparison wi...
