关于雌激素在大脑中的作用的争论仍然是妇女健康的基础、转化和临床科学的前沿。在这里,我提供了一个综合性的分析,雌激素诱导的可塑性,并将其作为一种策略,预测受雌激素影响的认知领域,除了变异的来源。雌激素增强可塑性的证据是增加神经发生,神经网络连接和突触传递。同时,雌激素增加葡萄糖转运,有氧糖酵解和线粒体功能,以提供维持增加的能量需求所必需的ATP。可塑性的模式预测,雌激素将优先影响更复杂的认知任务,时间要求和联想的挑战。因此,雌激素剥夺应该与这些功能的减少有关。雌激素对可塑性和生物能量学的调节为预测雌激素依赖性认知功能提供了一个框架,同时也为确定适合激素治疗的女性确定了变异性来源和潜在的生物标志物。
Controversy regarding estrogen action in the brain remains at the forefront of basic, translational and clinical science for women’s health. Here, I provide an integrative analysis of estrogen-inducible plasticity and posit it as a strategy for predicting cognitive domains affected by estrogen in addition to sources of variability. Estrogen enhancement of plasticity is evidenced by increases in neurogenesis, neural network connectivity and synaptic transmission. In parallel, estrogen increases glucose transport, aerobic glycolysis and mitochondrial function to provide the ATP necessary to sustain increased energetic demand. The pattern of plasticity predicts that estrogen would preferentially affect cognitive tasks of greater complexity, temporal demand and associative challenge. Thus, estrogen deprivation should be associated with decrements in these functions. Estrogen regulation of plasticity and bioenergetics provides a framework for predicting estrogen-dependent cognitive functions while also identifying sources of variability and potential biomarkers for identifying women appropriate for hormone therapy.
