概括
炎症与遗传性前性痴呆症 (FTD) 有关. 这项研究发现,在有症状的MAPT和GRN突变载体中,特定的炎症蛋白调高,在有症状和前症状的载体中,IL-1α水平降低.
科学领域:
- 神经科学是一个神经科学.
- 免疫学 免疫学 免疫学
- 遗传学 是一个遗传学.
背景情况:
- 神经炎症是神经退行性疾病的关键因素,如前性痴呆症 (FTD).
- 之前对零星FTD的研究给出了关于炎症的不确定的结果.
- 对遗传性FTD及其炎症标志物的大规模调查缺乏.
研究的目的:
- 在大量遗传性FTD队列中研究细胞因子和化学因子的血水平.
- 确定与FTD不同基因突变相关的特定炎症特征.
- 探索遗传性FTD临床前阶段潜在的炎症变化.
主要方法:
- 在434个血样本中使用Mesoscale技术分析了30个炎症因素.
- 包括症状突变载体 (SMC),症状前突变载体 (PMC) 和非载体对照 (NC).
- 基于基因突变的分层分析:微管相关蛋白 (MAPT),进子素 (GRN) 和9号染色体开放阅读框架 (C9ORF72).
主要成果:
- 与对照人群相比,瘤衰老因子 (TNF) α,互白素 (IL) -7,IL-15,IL-16和IL-17A在MAPT和GRN SMC中被上调.

Overview
Gene Therapy
Gene therapy is a technique where a gene is inserted into a person’s cells to prevent or treat a serious disease. The added gene may be a healthy version of the gene that is mutated in the patient, or it could be a different gene that inactivates or compensates for the patient’s disease-causing gene. For example, in patients with severe combined immunodeficiency (SCID) due to a mutation in the gene for the enzyme adenosine deaminase, a functioning version of the gene can be inserted. The...
Glucose Transporters
Glucose transporters facilitate the transport of glucose across the cell membrane. In addition to glucose, some glucose transporters can also aid the movement of other hexoses such as fructose, mannose, and galactose.
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:

Genome-wide Association Studies-GWAS
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

Alzheimer Disease l: Introduction
Alzheimer disease is a chronic, progressive, and irreversible neurodegenerative disorder and the most common cause of dementia in older adults. It leads to gradual neuronal loss, causing cognitive decline, behavioral changes, and loss of functional independence.Risk Factors and EtiologyThe disease is multifactorial. Age is the strongest risk factor, with prevalence doubling every 5 years after age 65. Genetic factors include mutations in genes such as APP, PSEN1, and PSEN2, which are associated...
Huntington Disease l: Introduction
Huntington disease or HD is a progressive, fatal neurodegenerative disorder inherited in an autosomal dominant pattern.PathophysiologyIt is caused by expansion of the CAG trinucleotide repeat in the HTT gene on chromosome 4 (4p16.3), producing an abnormal huntingtin protein with an expanded polyglutamine tract. This misfolded protein disrupts cellular function, leading to neuronal death. Normal alleles have ≤26 repeats, 27–35 are intermediate (risk of expansion), 36–39 show reduced penetrance,...
