This review synthesizes the divergent signaling architectures of major MDPs, including Humanin-FPR2/gp130, MOTS-c-AMPK/NRF2-LARS1/mTORC1, SHLP2-CXCR7, and SHMOOSE's genotype-dependent activity, and outlines how these mechanisms produce disease-specific outcomes.

The review also addresses the role of anti-inflammatory compounds, including omega-3 polyunsaturated fatty acids and low-dose aspirin, in mitigating NF-κB and IL-6 signaling to protect mitochondrial health.
The resulting metabolic flexibility, defined as the ability to efficiently switch between lipid and glucose oxidation, is enhanced through repeated exercise, counteracting age- and disease-related mitochondrial and functional decline.
Together, these adaptations demonstrate the importance of inter-tissue signaling in maintaining energy homeostasis and preventing sarcopenia, obesity, and insulin resistance.
