概括

脑周神经网络 (PNNs) 在精神分裂症 (SCZ) 患者的大脑中减少. 这一对死后研究的系统审查表明PNN缺陷可能会导致SCZ病理生理学.

科学领域:

神经科学是一个神经科学.
神经生物学神经生物学神经生物学
精神病学是一个精神病学.

背景情况:

精神分裂症 (SCZ) 发病与关键的大脑发育相吻合,包括抑制网络成熟.
围神经网络 (PNN) 对于抑制电路的发展至关重要,它覆盖了含有帕瓦胺的GABAergic 内神经元 (PVIs).
假设PNN异常是SCZ病理生理学的关键因素,可能导致电路中断.

研究的目的:

在对精神分裂症患者 (SCZ) 的死后大脑研究中系统评估周神经网络 (PNN) 密度.

主要方法:

在PubMed,Embase和Scopus数据库中进行了系统搜索.
对报告SCZ受试者死后大脑中PNN密度的病例控制研究进行了定性审查.
分析了7项纳入研究的结果,注意到研究的大脑区域的变化,如背侧前额叶皮质 (DLPFC) 和杏仁体.

主要成果:

在七项研究中,有六项报告说,SCZ患者的PNN密度显著降低.
一项研究表明,PNN密度下降的趋势.
在SCZ中,在不同大脑区域观察到PNN密度的持续减少.

结论:

这些发现支持了PNN密度缺陷与精神分裂症病理生理学有关的假设.
尽管结果一致,但研究数量有限和方法异质性凸显了进一步研究的必要性.
未来的研究应该采用标准化的方法,并旨在复制以加强这些发现.

关键词:

宏都里丁硫酸盐蛋白质糖类 (chondroitin sulphate proteoglycans) 是一种具有重要作用的蛋白质糖类.细胞外矩阵是细胞外矩阵.帕尔瓦尔胺是什么?周神经网络是什么?周神经网络在死后进行尸检.精神错乱是一种精神病.

Neural Regulation

Neural Regulation

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

Biological Causes of Schizophrenia

Biological Causes of Schizophrenia

Schizophrenia, a severe psychiatric disorder, arises from a complex interplay of biological factors, including genetic predisposition, structural brain abnormalities, neurotransmitter dysregulation, and developmental irregularities. These factors collectively contribute to the onset and progression of the disorder, which typically manifests in late adolescence or early adulthood.
Genetic Factors in Schizophrenia
The genetic basis of schizophrenia is strongly supported by family and twin...

Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders

Schizophrenia is a neurodevelopmental disorder whose origins are rooted in complex genetic components. Despite our burgeoning understanding, the pathophysiology of this disorder remains incompletely deciphered.
Researchers have identified genetic factors that increase susceptibility to schizophrenia, underscoring the intricate interplay between genetics and environment in disease development. At the core of schizophrenia's pathophysiology is excessive dopaminergic neurotransmission within...
