Proposed network framework links mitochondrial, nutrient-sensing and inflammatory aging processes
A narrative review proposes that aging reflects destabilization of interacting regulatory networks, with mitochondrial quality control, nutrient sensing and chronic inflammation as a putative central core; the framework is hypothesis-generating, not validated. [1]

The key findings
The review proposes aging as progressive destabilization of interacting regulatory networks, with mitochondrial quality control, nutrient sensing and chronic inflammation as a putative central core. [1]
The authors describe the framework as hypothesis-generating rather than formally validated. [1]
Interventions at high-centrality nodes are proposed to act by reconfiguring network dynamics rather than correcting individual pathways. [1]

Proposed network core of aging biology
The review starts from the observation that aging is the dominant risk factor for most chronic diseases, but existing frameworks list hallmarks of aging without explaining how they converge into organism-level decline and multimorbidity. It introduces a systems-level framework in which aging is progressive destabilization of interacting regulatory networks. Mitochondrial quality control, nutrient-sensing pathways and chronic inflammatory signaling are described as a putative high-centrality network core. The authors state that the framework is hypothesis-generating rather than formally validated.

How the proposed nodes interact
According to the review, mitochondria coordinate redox balance, bioenergetics and transcriptional adaptation. NAD-dependent signaling and activation of the NLRP3 inflammasome are said to propagate perturbations across regulatory layers. On this basis, the authors argue that neurodegenerative, cardiovascular, metabolic and oncological phenotypes could be emergent consequences of shared network instability. Reframing the hallmarks as coupled network nodes is meant to shift attention from isolated mechanisms to system-level resilience and non-linear dynamics. These are conceptual arguments, not tested causal findings.

Interventions framed as network recalibration
The review discusses interventions aimed at high-centrality nodes: mTOR modulation, NAD restoration, mitophagy activation and anti-inflammatory strategies. These may, in the authors' framing, act system-wide by reconfiguring network dynamics rather than correcting individual pathways. The perspective suggests that biomarker-stratified, network-calibrated interventions could offer a broader systems-level rationale than single-pathway approaches. No intervention was tested here, and no efficacy, safety or lifespan benefit is reported.

How to interpret this
Abstract only; the full text was not reviewed. This is a narrative and conceptual review, and the authors explicitly state that the proposed framework is hypothesis-generating rather than formally validated. No intervention was tested, and no efficacy, safety or lifespan outcomes are reported.
Based on the study abstract; the full paper, tables and supplementary data were not reviewed.
