In this opening lecture, Marvin Edeas, founder of the World Mitochondria Society and organizer of Targeting Longevity, introduces the central vision of the meeting:

Aging as a progressive loss of coordination between biological systems. Longevity is increasingly understood as the capacity of living organisms to maintain resilience through continuous dialogue between mitochondria, microbiota, metabolism, and cellular signaling.

The presentation examines how extracellular vesicles, microbial metabolites, and mitochondrial signaling pathways orchestrate communication across organs, cells, and microbial ecosystems. These interactions regulate adaptation to metabolic and environmental stress and influence long term biological stability.

Rather than focusing on isolated mechanisms, this systems perspective proposes that longevity strategies should aim to preserve biological coherence over time. By placing mitochondria microbiota crosstalk at the center of aging biology, the lecture establishes the conceptual foundation of the meeting and frames longevity as the science of resilience. 

Point of View on Aging and Longevity

For decades, longevity research has focused on identifying targets. Pathways have been inhibited, genes silenced, senescent cells removed, and mitochondrial function enhanced. Despite these advances, aging continues to progress.

A different interpretation is emerging. Aging may not simply reflect damage accumulation but rather a gradual loss of coordination between biological systems. Mitochondria communicate with immunity. Microbiota influence metabolism. Redox signaling shapes repair. Cellular networks constantly exchange information to maintain adaptation.

When this dialogue weakens, resilience declines. Aging can therefore be viewed as a breakdown in biological communication. This perspective shifts the focus away from isolated interventions toward restoring systemic coherence.

Targeting Longevity 2026 adopts this framework and explores several central questions. Is aging fundamentally a communication failure? Can restoring mitochondria microbiota dialogue improve resilience? Should longevity strategies prioritize coordination over isolated targets? How can biological coherence be preserved over time?

This approach suggests that the next breakthrough in longevity science may not come from a single therapeutic intervention but from redefining aging as a systems level phenomenon and developing strategies that restore biological dialogue.
