まとめ
100歳高齢者は生物学的な老化のばらつきを示し、健康状態が良いほど生物学的な年齢が若いことと関連していました。特定の免疫細胞プロファイルと臨床的要因が生物学的な年齢の進行と相関しており、極端な長寿における典型的な免疫老化の概念に疑問を呈しています。
科学分野:
- ジェロサイエンス;免疫学;長寿研究
背景:
- 生物学的な老化と免疫老化は、長寿の鍵となります。;100歳高齢者におけるそれらの相互作用はよく理解されていません。;100歳高齢者は、老化研究のためのユニークなモデルを表します。
研究 の 目的:
- コロンビアの100歳高齢者における生物学的年齢(PhenoAge)と免疫老化の関係を調査すること。;生物学的年齢と免疫状態に関連する臨床変数を特定すること。;異なる100歳高齢者の老化軌跡における免疫プロファイルを探索すること。
主な方法:
- 160人のコロンビアの100歳高齢者を対象とした横断研究。;PhenoAgeを使用して生物学的年齢を評価しました。;サイトカインプロファイリングとリンパ球免疫フェノタイピングを実施しました。;生活の質、健康状態、および臨床変数に関するデータを収集しました。
主要な成果:
- 生物学的な年齢が高いほど、抑うつ症状、喫煙歴、RANTESおよびG-CSFの上昇、特定のCD8+ T細胞フェノタイプ(例:TEMRA細胞)と関連していました。;生活の質と健康状態が良いほど、生物学的な年齢が低いことと関連していました。;活発、回復力がある、または脆弱と分類された100歳高齢者は、同様のサイトカインレベルを示しました。
結論:
- 本研究の結果は、100歳高齢者における免疫老化の普遍的な概念に疑問を呈しています。;生物学的年齢は、極端な長寿における特定の臨床的および免疫学的要因と関連しています。;トランスレーショナルジェロサイエンス研究の重要性を強調しています。

The Effect of Aging on Tissues
4.0K
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...

Pharmacodynamics in Geriatric Patients: Effects of Age
278
Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...

Aging

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...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption
761
As individuals age, their body's physiology evolves, affecting drug pharmacokinetics. The most apparent changes occur in the gastrointestinal tract, where an increase in gastric pH, a delay in gastric emptying, and a reduction in gastrointestinal motility are observed. Remarkably, these changes do not substantially modify the absorption of orally administered drugs, particularly those absorbed via passive diffusion.Transdermal drug delivery emerges as a highly viable method for older adults due...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Metabolism
267
Geriatric patients show significant variation in how their bodies process medications, which can change how effective and safe treatments are. The liver is the primary organ where drug metabolism occurs, involving two main types of chemical reactions: phase I and II. Phase I metabolism is driven by the cytochrome P450 enzyme system, which includes key types such as CYP3A, CYP2D6, and CYP2C9. Research indicates that while aging doesn't notably alter the levels or activity of these enzymes, it...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Distribution
298
Drug distribution in the human body is influenced by several factors, including plasma protein concentration, body composition, blood flow, tissue-protein concentration, and tissue fluid pH. Among these, changes in plasma protein concentration and body composition due to aging significantly affect how drugs are distributed within the body. Specifically, aging is associated with a decrease in albumin levels by about 10% and an increase in α1-acid glycoprotein levels. These alterations are...
