Altered intercellular communication
Signaling between cells becomes dysregulated, often promoting chronic inflammation.
Aging shifts endocrine milieu (somatopause, declining sex steroids), neurotransmitter tone, and neuroimmune crosstalk. Adipose–liver–brain signaling and circadian misalignment worsen metabolic flexibility and systemic coordination.
How to minimize altered intercellular communication
- Circadian entrainment: morning light, regular sleep timing, and consistent meal windows stabilize neuroendocrine rhythms.
- Maintain lean mass and VO2max—key inputs to anabolic hormone signaling within physiologic bounds.
- Exogenous hormone replacement requires individualized clinical risk–benefit—not blanket longevity prescriptions.
- Stress-axis modulation via social connection, cognitive engagement, and recovery practices affects systemic signaling.
