- 遺伝学; 神経科学; 精神医学
背景:
- 認知症のゲノム座は知られているが、タンパク質コードバリアントの役割は不明のままである。; 認知症と神経精神医学的形質との間の遺伝的関連性は、さらなる調査を必要とする。
研究 の 目的:
- 認知症および68の神経精神医学的形質に対するタンパク質コードバリアントの影響を調査する。; 認知症と神経精神医学的状態との間の遺伝的相関を決定する。; 遺伝子-表現型連鎖に対するマルチオミクスの寄与を探求する。
主な方法:
- 350,770人のUKバイオバンク参加者を対象とした大規模全エクソームシーケンシング。; 遺伝的相関解析のための負担遺伝率回帰。; 脳構造、血中タンパク質、および炎症のマルチオミクス解析。
主要な成果:
- 神経精神医学的疾患に関連する20の新規遺伝子を同定し、そのうち7つは認知症(4つは新規)に関連していた。; SYNGAP1は認知機能に対して多面的な効果を示した。; 29の遺伝子が右内側眼窩前頭皮質と相関していた。; 認知症、脳卒中、神経変性疾患、および一部の精神疾患間の遺伝的関連性の共有が見られた。

Infection
11.6K
When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

Urinary Tract Infection II: Pathophysiology
524
The pathophysiology of urinary tract infections (UTIs) encompasses several progressive stages, beginning with bacterial colonization and culminating in potential systemic complications if untreated. UTIs are primarily initiated by bacteria, such as Escherichia coli, which often originate from the gastrointestinal tract and migrate to the urinary system through the periurethral area. This migration can occur via several routes, including improper hygiene practices, sexual activity, or...

Cystic Fibrosis: Pathogenesis
676
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,...

Stages of Infection
64.7K
Stages of infection describe what happens to a susceptible host once a pathogen invades the human body. The stages of infection are incubation, prodromal, illness, stage of decline, and convalescence. The incubation stage is the period from exposure to a pathogen until symptoms start. The infected person is unaware of impending illness as the pathogens grow and multiply within the body. The duration may vary depending on the type of infection. The incubation period of measles averages ten to...

Defense Against Bacterial Pathogens
2.6K
The human immune system is a complex network of cells, tissues, and organs that work together to defend the body against bacterial infections. It consists of various immune cells, each playing a specific role in the defense mechanism.
Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...
