对啮齿动物胎儿的研究提供了证据,表明早期出现的行为,如吸吮反应,取决于发育中的多巴胺能系统。虽然已经在多巴胺的操纵和改变的行为反应之间建立了联系,但涉及的特定神经通路尚未被发现。在这项研究中,我们研究了黑质纹状体通路的神经行为输出,使用Pitx 3 ak/2 J小鼠模型(Pitx 3)。广泛用于帕金森病的研究,Pitx 3小鼠仅在黑质纹状体通路中具有非常特定的多巴胺能神经元的产前损失。由于这种特异性,我们假设黑质纹状体通路特异性的行为缺陷可以通过给予多巴胺前体3,4-二羟基苯丙氨酸(L-多巴)来逆转。为了检验这一假设,在出生前一天,对纯合子突变体和杂合子对照胎儿受试者给予4种剂量(0、25、50或75 mg/kg)中的1种L-多巴。从行为观察的视频记录中对胎儿行为的量化进行评分。所用的行为测量是(a)自发运动活动;(B)状态组织,来自高振幅和低振幅运动的量化;(c)肢体间运动同步性,肢体协调的测量;和(d)口腔抓握,类似于新生儿吮吸反应。在Pitx 3突变体中观察到的特定行为缺陷通过L-多巴给药以剂量依赖性方式逆转。然而,不同的缺陷需要不同的剂量逆转,这表明一些早期出现的行为可能对左旋多巴的管理更敏感。总之,这项研究提供了有价值的信息产前行为依赖于黑质纹状体通路。(PsycINFO数据库记录(c)2016阿帕,保留所有权利)
Studies of fetal rodents have provided evidence that early emerging behaviors, such as the suckling response, are dependent on the developing dopaminergic system. Although connections have been made between manipulations of dopamine and altered behavioral responses, the specific neural pathways involved have yet to be discovered. In this study, we examined the neurobehavioral output of the nigrostriatal pathway, using the Pitx3 ak/2J mouse model (Pitx3). Used extensively in the study of Parkinson’s disease, the Pitx3 mouse has very specific prenatal loss of dopaminergic neurons solely in the nigrostriatal pathway. Because of this specificity, we hypothesized that behavioral deficits specific to the nigrostriatal pathway would be reversed with administration of the dopamine precursor 3, 4-dihydroxyphenylalanine (L-dopa). To test this hypothesis, homozygous mutant and heterozygous control fetal subjects were administered 1 of 4 doses (0, 25, 50, or 75 mg/kg) of L-dopa on the day before birth. Quantification of fetal behavior was scored from video recordings of behavioral observations. The behavioral measures used were (a) spontaneous movement activity;(b) state organization, from quantifications of high-and low-amplitude movements;(c) interlimb movement synchrony, a measure of limb coordination; and (d) oral grasp, similar to a newborn infant suckling response. Specific behavioral deficits observed in the Pitx3 mutants were reversed by L-dopa administration in a dose-dependent manner. However, different deficits required dissimilar doses for reversal, suggesting that some early emerging behaviors may be more sensitive to the administration of L-dopa. Taken together, this study provides valuable information about prenatal behaviors dependent on the nigrostriatal pathway.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
