The distribution of dopamine D2 receptors was studied using the autoradiographic technique on rabbit pituitary gland sections incubated in the presence of [3H]spiroperidol. D2 receptors were absent from the intermediate lobe as already reported. In the anterior lobe, the location of D2 receptors exactly overlapped that of the prolactin-producing cells revealed by immunocytochemistry on the sections used for autoradiography. No topographical relationships could be found between the D2 receptors and the TSH-producing cells which are known to be inhibited by dopamine in the rat.
采用放射自显影技术，在存在[3H]螺哌啶醇的条件下对兔垂体切片进行孵育，研究多巴胺D2受体的分布。如先前报道，中间叶不存在D2受体。在前叶，D2受体的位置与放射自显影所用切片上免疫细胞化学显示的催乳素分泌细胞的位置完全重叠。在大鼠中，已知促甲状腺激素分泌细胞受多巴胺抑制，但未发现D2受体与促甲状腺激素分泌细胞之间存在拓扑关系。
