背景情况:

碳酸受体1 (HCAR1) 是一种由乳酸激活的G蛋白结合受体.
HCAR1在大脑中表达,并与神经元功能和损伤修复有关.
缺氧性缺血性脑病变 (HIE) 是新生儿脑损伤和的主要原因.

研究的目的:

研究新生儿大脑发育中的HCAR1表达和功能.
确定HCAR1在与HIE相关的发作的作用.

主要方法:

定量逆转录酶聚合酶连锁反应 (RT-qPCR) 用于小鼠大脑中HCAR1表达分析 (产后10-50天).
神经元特性和自发刺激后突触电流 (sEPSCs) 的电生理学记录在海马神经元中从暴露于乳酸盐的HCAR1淘汰和野生类型小鼠中.
电脑电图 (EEG) 用于评估HCAR1淘汰和野外类型小鼠的负担,这些小鼠遭受过缺氧缺血症 (HI).

主要成果:

在新生儿小鼠大脑中检测到HCAR1的表达在出生后的第10天,与成人水平相比.

Ligand-Gated Ion Channel Receptor: Gating Mechanism

Ligand-gated ion channels are transmembrane proteins that play a vital role in intercellular communication and functions of the nervous system. They allow the influx of ions across the membrane once the neurotransmitter binds, allowing the subsequent transmission of electrical excitation across the neurons. Other ligand-gated ion channels, like the γ-aminobutyric acid (GABA) receptor, permit anions like chloride into the cells on the binding of the GABA molecule. Their entry into the cell...

Seizures: Classification

Seizures: Classification

Epilepsy is primarily characterized by unpredictable seizures, either provoked by an identifiable factor, such as injury or illness, or unprovoked, occurring spontaneously without apparent cause.
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:
