まとめ
変形性関節疾患(DJD)は、特に血管性認知症のリスクを有意に増加させます。この関連は特定の血液タンパク質によって媒介され、炎症と血管の問題が主要なメカニズムであることを示唆しています。
科学分野:
- 生物医学; 神経科学; 老年医学
背景:
- 変形性関節疾患(DJD)は、変形性関節症や脊椎変性などの状態を含みます。; アルツハイマー病や血管性認知症を含む認知症は、重大な公衆衛生上の課題となっています。; DJDと認知症リスクの関係、およびその生物学的メカニズムは、さらなる調査が必要です。
研究 の 目的:
- DJDと認知症発症リスクとの関連を調査すること。; DJDと認知症の関連を説明する可能性のあるプロテオームメディエーターを同定すること。; これらのメカニズムに基づいた認知症予防のための潜在的な治療標的を探索すること。
主な方法:
- 500,805人のUKバイオバンク参加者を対象とした前向きコホート研究が実施されました。; DJDの診断と認知症の転帰が、中央値14.45年間追跡されました。; 多変量Cox回帰、傾向スコアマッチング、および血漿プロテオームプロファイリングを使用して、関連を分析し、メディエーターを同定しました。
主要な成果:
- DJDは、全原因認知症(ACD)および血管性認知症(VaD)のリスクを有意に増加させましたが、アルツハイマー病(AD)のリスクは増加させませんでした。; プロテオーム解析により、DJDとACDの関連を著しく媒介するHAVCR1、GDF15、COL6A3を含む18の血漿タンパク質が同定されました。; 年齢、活動レベル、および手術歴に基づく効果修飾が観察されました。
結論:
- 変形性関節疾患は、認知症のリスク増加と独立して関連しています。; HAVCR1、GDF15、COL6A3などのタンパク質が関与する全身性のプロテオーム変化が、この関連を媒介します。; 炎症と血管機能障害が中心的なメカニズムとして強調されており、認知症リスク層別化と治療介入の潜在的な道を提供します。

Alzheimer's Disease: Overview
1.6K
Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ...

The Proteasome
10.0K
Eukaryotic cells can degrade proteins through several pathways. One of the most important amongst these is the ubiquitin-proteasome pathway. It helps the cell eliminate the misfolded, damaged, or unwarranted cytoplasmic proteins in a highly specific manner.
In this pathway, the target proteins are first tagged with small proteins called ubiquitin. A series of enzymes carry out the ubiquitination of the target proteins - E1 (ubiquitin-activating enzyme), E2 (ubiquitin-conjugating enzyme), and E3...

Regulated Protein Degradation
8.7K
It is vital to regulate the activity of enzymatic as well as non-enzymatic proteins inside the cell. This can be achieved either through creating a balance between their rate of synthesis and degradation or regulating the intrinsic activity of the protein. Both these regulation mechanisms play an essential role in the normal functioning of cells.
Protein degradation plays two important roles in the cells. It helps to protect cells from misfolded or damaged proteins before they lead to a...

Dementia

Dementia is a collective term for cognitive disorders primarily affecting memory, thinking, and reasoning. It is not a specific disease but a syndrome, with Alzheimer's disease being the most common cause, accounting for approximately 60-80% of cases. Other types include vascular dementia, Lewy body dementia, and frontotemporal dementia. Dementia affects millions worldwide, particularly older adults, though it is not a normal part of aging.
