まとめ
ヒト免疫不全ウイルス (HIV) の患者は,感染していない人と比較して,表遺伝的老化が加速している. この加速された老化は,抗レトロウイルス治療 (ART) 状態に関係なく観察され,HIVが生物学的老化に持続的影響を及ぼすことを示唆しています.
科学分野:
- エピジェネティクス
- ウイルス学
- ゲロントロジー
背景:
- ヒト免疫不全ウイルス (HIV) 感染は,生物学的老化を加速させる.
- エピジェネティック・クロックは 生物学的年齢を 分子的に測定します
- HIVの表遺伝的老化を理解することは 長期的な健康結果の管理に不可欠です
研究 の 目的:
- HIV感染者 (PLWH) と未感染者における表遺伝的老化の強さを比較した研究を体系的に検討する.
- PLWHにおける加速された表遺伝的老化に関する証拠を合成する.
主な方法:
- 25件の研究を体系的に検討した.
- 年齢に関係する表遺伝的変化の定量的な検査
- PLWHとHIV陰性個人を比較した研究を含める.
主要な成果:
- 大半の研究 (22/ 25) は,PLWHにおける表遺伝的老化の加速を示しています.
- ART治療と未治療のPLWHの両方でエピジェネティックな加齢が観察されました.
- 方法論的差異と未解決の混同要因 (例えばBMI,併発症,ライフスタイル) が研究全体で認められた.
結論:
- 証拠は,PLWHの加速された表遺伝的老化を強く示唆しています.
- 組織特異的な効果,バイオマーカー,および混同因子を調査するためにさらなる研究が必要である.
- 研究は,ARTの影響,診断年齢,および時効性に関するエピジェネティック・エイジングを調査する必要があります.

The Effect of Aging on Tissues
2.4K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

Epigenetic Regulation
3.1K
Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

Mechanisms of Retrovirus-induced Cancers
5.3K
Retroviruses are RNA viruses that have been shown to cause cancers in diverse species, including chickens, mice, cats, and monkeys. The RNA genomes of these viruses are first reverse-transcribed into single and then double-stranded DNA (dsDNA) copies. This dsDNA called proviral DNA then integrates into the host genome. Subsequently, the host cell transcribes the proviral DNA in concert with the chromosomal DNA. This leads to the production of viral RNA and proteins that assemble at the host...

Aging
179
Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...

Spreading of Chromatin Modifications
8.5K
The histone proteins in the nucleosomes are post-translationally modified (PTM) to increase or decrease access to DNA. The commonly observed PTMs are methylation, acetylation, phosphorylation, and ubiquitination of lysine amino acids in the histone H3 tail region. These histone modifications have specific meaning for the cell. Hence, they are called "histone code". The protein complex involved in histone modification is termed as "reader-writer" complex.
