研究总结

The long-term goal of the Auerbach Laboratory is to investigate the prevalence, risk factors, and mechanisms for dual electrical disturbances of the brain (seizures) and heart (arrhythmias). We are particularly interested in improving our understanding of the multi-system cascade of events that lead to Sudden Unexpected Death in Epilepsy Patients (SUDEP), 这将有可能识别出猝死症的标志.

Bedside-to-Bench-to-Bedside方法: 我们有一个多系统的大脑 & 心脏)和多尺度(分子), biochemical, cellular, organ, in vivo, and clinical) approach to investigating electrical diseases of the brain and heart. We perform patient database analyses to examine the co-prevalence and risk of seizures 和心律失常. Then using cellular and animal models of the disease we perform molecular/biochemical and electrophysiological approaches to understand the underlying mechanisms for these neuro-cardiac pathologies. Ultimately, 使用患者数据库验证了这些结果, 这样就完成了从床到台到床的完整范例.

Multi-System Approach to Understanding and Treating Genetic Ion Channel Diseases: The Auerbach Lab’s “Bedside-to-Bench-to-Bedside” approach to research involves clinical studies of humans with a history of electrical disturbances in the brain (seizures/epilepsy) and heart (arrhythmias). Additionally, we generated a genetic rabbit model of an inherited cardiac arrhythmia disease. It enables us to explore the underlying causes for these abnormalities by performing experiments at the molecular, biochemical, cellular, 以及整个动物的水平.  研究项目的每一个方面都能促进和激励其他方面, 创造一个富有成效的研究周期.

临床研究项目(回顾性数据集) & 可穿戴式传感器的前瞻性记录

Millions of Americans have epilepsy and they are at a high risk of sudden death (e.g., SUDEP.不幸的是,潜在的机制仍然未知.

As cardiac events are one mechanism for SUDEP, we are starting with the heart. 癫痫的遗传模型, 我们证明了观察大脑外部是至关重要的, as these mutations lead to alterations in cardiac electrical function, 包括离子通道活性的改变, 兴奋过度, 和心律失常.

遵循从工作台到病床的范式, we reported cases of cardiac ECG abnormalities and near-lethal arrhythmias in patients with severe genetic forms of epilepsy. We use analytical tools that are well accepted in the field of cardiology, 但对癫痫和猝死症还是新手, to identify epilepsy patient populations at risk of cardiac-related SUDEP. Additionally, we use wearable technology to acquire continuous multi-system recordings, 这能让我们捕捉到医院外的事件吗. The goal is to develop a comprehensive SUDEP risk assessment tool to help identify people with epilepsy who are at risk for SUDEP, 以便采取措施防止猝死的发生.

SUDEP

临床数据库研究: Data is collected from patients during interictal baseline periods, and surrounding seizures. The Auerbach Lab studies the patients’ ECG during these time periods in hopes of identifying cardiac biomarkers for SUDEP risk.

癫痫发作参与者的百分比图表

从患者层面开始, we demonstrated that patients with a classically studied inherited cardiac arrhythmia disease, 长QT综合征(LQTS), 癫痫发作的风险增加了吗. 然而,这些癫痫发作的根本原因尚不清楚. 我们建立了一种新的LQTS突变兔模型, 会重现LQTS患者的神经心脏病变. It enables us to conduct translational studies to investigate the mechanisms for arrhythmias and seizures in LQTS. 正在进行的实验方法是在分子层面, biochemical, 细胞电生理学, organ, 以及体内水平.

长QT综合征: We showed that there is a higher prevalence of a history of seizures/epilepsy in patients with an inherited cardiac arrhythmias disease, 长QT综合征, 与基因型阴性的家庭成员相比. Patients with 长QT综合征 Type 2 showed the highest prevalence of seizures.
