项目摘要
Project Summary
Several clinical trials have found that intranasal oxytocin (OT) treatment is not practically viable in its current
form for improving core social symptoms in autism spectrum disorders (ASD). The current intranasal OT
treatment has been criticized for its often weak and inconsistent effects, demanding an important need to explore
new ways to improve its efficacy and reliability in modulating the OT system. While much less studied, the central
opioid system has also been implicated in ASD based on the opioid dysregulation found in certain cases of ASD,
as well as the well-known modulatory effects of opioid agonists, such as morphine, and its receptor antagonists,
such as naloxone (NAL), in regulating social behaviors. In this translational non-human primate proposal, we will
investigate a new alternative therapeutic option in improving core social functions by exploiting the robust
regulatory relationship between the central OT and opioid systems. Our pharmacological study in non-human
primates recently provided a proof of concept of this combined pharmacological approach in more effectively
modulating social attention. The combined intranasal administration of OT and NAL (OTNAL) enhanced
spontaneous social attention and contingent gaze dynamics following interactive eye contact over and beyond
the summed effects from administering OT alone and NAL alone, indicating a combinatorial benefit of OTNAL.
Capitalizing on this finding, we now propose to determine the optimal doses of OT and NAL in the combined
OTNAL format, its corresponding cerebrospinal fluid markers of successful OTNAL interventions, as well as the
neurophysiological markers underlying the combinatorial benefits in the domain of social attention. We will first
obtain comprehensive dose-response functions for the OTNAL intervention during spontaneously occurring real-
life social gaze interactions and assess the corresponding changes in cerebrospinal fluid OT levels due to
OTNAL compared to other conditions (Aim 1A, 1B). We will then study how neural activity patterns within and
across two key brain nodes in social processing, the amygdala and the anterior cingulate cortex, are impacted
by OTNAL (Aim 2). Finally, we will test causal contributions of these two regions for the OTNAL effects by
blocking OT-binding receptor types focally in these areas (Aim 3). The results from this work will offer novel
mechanistic insights into the combined pharmacological approach using OTNAL to more vigorously promote
social engagements in the primate brain. Such results will help set the stage for translating the combinatorial
benefit of using intranasal OTNAL for more effectively and reliably reducing core social symptoms in ASD.
项目概要
多项临床试验发现,鼻内催产素 (OT) 治疗在目前的情况下实际上并不可行。
改善自闭症谱系障碍 (ASD) 核心社会症状的形式。目前鼻内OT
治疗因其效果往往较弱且不一致而受到批评,迫切需要探索
提高其调节 OT 系统效率和可靠性的新方法。尽管研究较少,但中央
基于在某些自闭症谱系障碍病例中发现的阿片类药物失调,阿片类药物系统也与自闭症谱系障碍有关,
以及阿片类激动剂(例如吗啡)及其受体拮抗剂众所周知的调节作用,
例如纳洛酮(NAL),用于调节社会行为。在这个翻译性非人类灵长类动物提案中,我们将

OTNAL 与其他条件的比较(目标 1A、1B)。然后我们将研究内部和外部的神经活动模式如何
社会处理中两个关键的大脑节点——杏仁核和前扣带皮层——受到影响

使用鼻内 OTNAL 可以更有效、更可靠地减少自闭症谱系障碍 (ASD) 的核心社会症状。
