This study was carried out to examine the effects of early postnatal maternal separation stress on the brain development, biological properties of adipose tissue, and the interactions between them. Wistar rats were separated from their mothers in early life. The level of various neurotrophic factor ligands/receptors in the cerebral cortex and cerebellum showed abnormal time-dependent fluctuations. Given that these factors play important roles in brain development, it can be speculated that the altered expression of these factors induced by maternal separation may interrupt normal brain development and ultimately lead to functional disruption. Furthermore, there was a significant change in the level of various mitochondrial energy-expenditure molecules. Given that these molecules influence the mitochondrial metabolism, our study indicates that early postnatal maternal deprivation can influence the fate of adipose tissue proliferation, presumably leading to obesity later in life.

这项研究的目的是检查产后早期母亲分离应激对大脑发育、脂肪组织的生物学特性以及它们之间的相互作用的影响。威斯塔鼠在幼年时就与母亲分离。大脑皮层和小脑中各种神经营养因子配体/受体的水平表现出异常的时间依赖性波动。鉴于这些因素在大脑发育中发挥着重要作用，可以推测，母体分离引起的这些因素的表达改变可能会中断正常的大脑发育，并最终导致功能破坏。此外，各种线粒体能量消耗分子的水平也发生了显着变化。鉴于这些分子影响线粒体代谢，我们的研究表明，产后早期的母亲剥夺会影响脂肪组织增殖的命运，可能导致以后的肥胖。
