[Abstract]  

Long-term consequences of stroke significantly impair the quality of life in a growing population of stroke survivors. Hippocampal adult neurogenesis has been hypothesized to play a role in the pathophysiology of cognitive and neuropsychiatric long-term sequelae of stroke. Reliable animal models of stroke are paramount to understanding their biomechanisms and to advancing therapeutic strategies. We present a detailed protocol of a transient cerebral ischemia model which does not cause direct ischemic damage in the hippocampus, allowing investigations into the pathophysiology of long-term neurocognitive deficits of stroke. Furthermore, we describe a protocol for obtaining acute hippocampal slices for the purpose of electrophysiological and morphological characterization of adult-borne

[摘要]  [摘要]中风的长期后果严重损害了越来越多的中风幸存者的生活质量。假定海马成年神经发生在中风的认知和神经精神病学长期后遗症的病理生理学中起作用。可靠的中风动物模型对于理解其生物机制和推进治疗策略至关重要。我们提出 暂时性脑缺血模型的详细协议,该模型不会在海马体中引起直接缺血损伤,从而可以研究中风的长期神经认知缺陷的病理生理学。此外,我们描述了一种用于获取成人海马颗粒细胞的电生理学和形态学特征的急性海马切片的协议。还讨论了与从小细胞(例如未成熟的成年颗粒细胞)进行电生理记录有关的特殊性。本协议可以通过多模式研究(行为,形态结构,生化)加以补充,以期有希望促进研究和中风的长期后遗症的发展以及发现新的治疗机会。

[背景]中风是在发达国家发病率和死亡率的重要原因引起急性和延迟赤字。虽然针对缺血性中风恢复血流的干预策略在降低急性发病率和死亡率方面已经变得更加有效,但中风的长期后果(如中风后抑郁和中风后认知功能障碍和痴呆症)目前正在逃避临床治疗(Wang等。,2010; Loubinoux等人,2012; Mijajlovic ...

[Abstract]  Atherosclerosis is a chronic inflammatory disease of large and medium-sized arteries. Apolipoprotein E-deficient (ApoE-/-) mice are used as experimental models to study human atherosclerosis. ApoE-/- mice are constitutively hyperlipidemic and develop intima plaques that resemble human plaques. Various issues including experimental design for lesion analysis, dietary conditions, isolation of the aorta, staining methods, morphometry, group size, age, the location within the arterial tree, and statistical analyses are important parameters that need to be addressed to obtain robust data. Here, we provide detailed methods to quantify aorta atherosclerosis.
