Infection01:20

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 Pathogens01:31

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...

科学分野:

  • 遺伝学;神経科学;バイオマーカー発見

背景:

  • 遺伝学はアルツハイマー病(AD)のバイオマーカー形質に大きく影響するが、特定の遺伝的要因は十分に理解されていない。;ADの病態生理を理解し、効果的な介入を開発するためには、遺伝的寄与の調査が不可欠である。

研究 の 目的:

  • アルツハイマー病(AD)のバイオマーカー形質の遺伝的基盤を探索すること。;ADリスクおよび主要バイオマーカーに関連する新規遺伝子バリアントおよびポリジーンリスクスコアを同定すること。

主な方法:

  • 3,707人の個人(AD患者1,697人、対照2,010人)に対して全ゲノムシーケンシングが実施された。;共通およびまれな遺伝子バリアントと、脳脊髄液(CSF)および血漿バイオマーカーを含むADバイオマーカー形質との関連解析が実施された。;ポリジーンリスクスコア(PRS)が開発され、ADリスクおよびバイオマーカーレベルとの関連について評価された。

主要な成果:

  • PRSは、ADリスクの増加、ミニメンタルステート検査(MMSE)スコアの低下、および血漿中p-tau217およびGFAPレベルの上昇と有意な関連を示した。;遺伝子ベースのまれなバリアント解析により、特定のADバイオマーカー形質に対してゲノムワイドな有意性を持つ3つの新規遺伝子(ABCA7、ECSIT、ADPRHL1)が同定された。;ABCA7のまれな損傷バリアントはMMSEスコアと、ECSITはCSF Aβ42と、ADPRHL1は血漿GFAPと関連していた。

結論:

  • ポリジーンリスクスコアとABCA7、ECSIT、ADPRHL1のまれなバリアントの両方が、アルツハイマー病のバイオマーカー形質に大きく寄与している。;これらの発見は、ADの病態生理に関する我々の理解を深めるものである。;同定された遺伝的要因は、ADの診断および治療戦略の新規ターゲットとなる可能性がある。
