Better immunity in later life: a position paper

Area of Science:

• Gerontology
• Immunology
• Public Health

Background:

• Ageing presents a significant challenge to healthcare systems globally.
• Immune system dysfunction with advancing age (immunosenescence) is critical to age-related mortality and reduced quality of life.

Purpose of the Study:

• To review and synthesize advancements in understanding the fundamental mechanisms of immunosenescence.
• To identify priority areas for future research and intervention in immune ageing.

Main Methods:

• Review of accumulated evidence from nonhuman model systems over the past decade.
• Synthesis of findings from a 2-day workshop involving original ImAginE consortium participants.

Main Results:

• Ageing involves a few common processes impacting multiple organ systems, leading to immune decline.
• Advances clarify cross-system dysregulation in ageing and suggest new intervention strategies.

Conclusions:

• Continued research into immunosenescence is essential for developing effective interventions.
• Focusing on identified priority areas can improve late-life health and mitigate age-related decline.
