生化/生理作用
催乳素是一种神经内分泌激素。催乳激素受体是一种跨膜糖蛋白，属于细胞因子造血受体家族。大量细胞和器官表达该受体，包括 B 细胞、T 细胞、巨噬细胞、单核细胞和嗜中性粒细胞。催乳素信号转导涉及 JAK/STAT 家族和 src 激酶家族。引起泌乳；抑制促性腺激素的分泌；释放受多巴胺抑制。

Individuals with intellectual disability frequently use antipsychotics for many years. This may have detrimental health effects, including neurological symptoms and metabolic and hormonal dysregulation, the latter possibly affecting bone metabolism. There is large variability in the degree in which antipsychotic
