The ontogenetic development of 'central' and 'peripheral' benzodiazepine (BZ) receptors was investigated in 3 different regions of the guinea pig brain. A marked difference in the developmental profile of these two types of binding sites was observed. The density of central-type receptors gradually increased during embryonic life (especially in cortex and cerebellum), without major changes after birth, while the reverse was true for peripheral-type binding sites. These data contrast with those previously reported in rat, suggesting species differences.
在豚鼠大脑的3个不同区域研究了“中枢”和“外周”苯二氮䓬(BZ)受体的个体发生发育。观察到这两种结合位点的发育情况存在显著差异。中枢型受体的密度在胚胎期逐渐增加(尤其是在皮质和小脑),出生后无明显变化,而外周型结合位点的情况则相反。这些数据与先前在大鼠中报道的数据形成对比,表明存在物种差异。
