概括

儿童的结核性硬化症涉及网络超同步. 结核内的神经元显示出更大的超同步,这表明结核在这种情况下会带来不良结果.

科学领域:

神经科学是一个神经科学.
发病学 (Epileptology) 是一个专业的学科.
发育神经科学的发展神经科学.

背景情况:

网络超同步是发作和与结构性大脑异常相关的神经发育障碍的关键机制.
结核性硬化综合体 (TSC) 是一种遗传性疾病,其特点是多个器官 (包括大脑) 中的瘤 (结核) 的生长,往往导致和认知缺陷.

研究的目的:

为了研究单个神经元的动作潜能行为和功能网络同步在患有结核性硬化症的儿童.
为了确定特定的解剖区域,特别是,是否与神经元活动和网络超同步的改变有关.

主要方法:

在患有结核性硬化症的儿童中,从206个神经元记录单个神经元活动 (动作潜力).
通过自相关性 (神经元对神经元) 和交叉相关性 (功能网络) 分析神经元发射模式.
通过不同解剖部位进行神经元活动比较:结核,结核的穿尾,和看起来正常的皮质.

主要成果:

在不同解剖位置的单个神经元发射模式 (自身相关性) 中没有发现显著差异.
功能网络分析 (交叉相关性) 显示,与其他解剖部位相比,结核对结核神经元之间的超同步倾向明显更高.
这种超同步性表明,结核在网络功能障碍中起着关键作用.

结论:

结核性硬化症相关的大脑结核是网络超同步的主要驱动因素.
这种超同步可能是发作和神经行为障碍的基础,在患有结核性硬化症的儿童中观察到.

Assembly of Complex Microtubule Structures

Assembly of Complex Microtubule Structures

Complex microtubule structures are present in resting cells and in dividing cells. In resting cells, they are responsible for maintaining the cellular architecture, tracks for intracellular transport, positioning of organelles, assembly of cilia and flagella. They mediate the bipolar spindle assembly for chromosomal segregation and positioning of the cell division plate in dividing cells. The formation of microtubule complex structures depends on the cell type, cell stage, and cell function.

Microtubules in Signaling

Microtubules in Signaling

The primary cilium, made up of microtubules, acts as antennae on the cell surfaces for relaying external stimuli into the cells. These fine hair-like structures are present, generally one per cell. These are non-motile cilia in a 9+0 microtubules arrangement, where the central pair of microtubules are absent. The primary cilia arise from the basal body embedded in the cell membrane. Intraflagellar transport (IFT) carries requisite proteins from the cytoplasm to the cilium because the primary...
