Healthy ageing: The struggle for maintaining T cells young

Area of Science:

• Immunology and Gerontology
• Cellular Aging Research

Background:

• Global health challenges like pandemics and cancer necessitate understanding aging.
• Societal shifts towards older populations highlight the importance of healthy aging.
• The T cell compartment is significantly impacted by the aging process, a key aspect of inflammaging.

Purpose of the Study:

• To review quantitative and qualitative changes in T cells during aging.
• To discuss pathophysiological factors accelerating age-related T cell dysfunction.
• To highlight novel strategies for rejuvenating T cell function to promote healthy aging.

Main Methods:

• Literature review of recent advancements in inflammaging research.
• Analysis of age-related changes in T cell compartments.
• Synthesis of emerging therapeutic strategies targeting T cell dysfunction.

Main Results:

• Aging leads to significant quantitative and qualitative alterations in T cells.
• Various pathophysiological factors contribute to and accelerate T cell aging.
• Emerging strategies show promise in restoring T cell function and "youthfulness".

Conclusions:

• Preserving or rejuvenating T cell function is crucial for healthy aging.
• A deeper understanding of inflammaging and T cell dynamics can inform interventions.
• Targeting age-related T cell dysfunction offers a pathway to improved healthspan.
