神经学神经学

背景情况:

初级状动力障碍 (PCD) 是一种罕见的遗传性疾病,影响运动,主要影响呼吸系统.
传导性听力损失 (CHL) 由中耳炎与溢出 (OME) 在PCD中很常见,但感觉神经听力损失 (SNHL) 的机制尚不清楚.

研究的目的:

为了研究SNHL的潜在机制在患有原发性纤维动力障碍 (PCD) 的患者.
探索PCD听力功能障碍的遗传基础,特别是不典型的表现.

主要方法:

一名52岁的男性被诊断患有PCD, situs inversus,呼吸道症状和毛缺陷的案例研究.
综合性听力学评估显示严重的双边SNHL.
鉴定病原性SH3TC2变体的遗传检测.

主要成果:

该患者出现了严重的双边SNHL,这是PCD的一个不常见的表现.
基因分析揭示了一种致病性SH3TC2变体,通常与Charcot-Marie-Tooth4C型疾病 (CMT4C) 相关.
这一发现表明PCD听力损失的潜在神经病变病因.

结论:

对于患有渐进性或非典型性听力损失的PCD患者来说,全面的听力学和遗传学评估至关重要.
这种SH3TC2突变表明,状腺功能障碍与影响听力的遗传神经病变之间可能存在联系.
需要进一步的研究,以了解PCD和神经病听力损失的交叉点,以改善患者的治疗结果.

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...

Mechanism of Ciliary Motion

Mechanism of Ciliary Motion

The ciliary structures were first seen in 1647 by Antonie Leeuwenhoek while observing the protozoans. In lower organisms, these appendages are responsible for cell movement, while in higher organisms, these appendages help in the movement of the extracellular fluids within the body cavities.
The cilia are made up of microtubules in a 9+2 arrangement, with nine microtubule doublet ring bundles, surrounding a pair of central singlet microtubule bundles. The doublet microtubule bundles are...

Cystic Fibrosis: Pathogenesis

Cystic Fibrosis: Pathogenesis

Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...
