Longevity & AgingApril 2026 Longevity Breakthroughs Span Muscles, Brain, and Biological Age
April 2026 brought a wave of longevity research across multiple fronts. Key findings include a combination NAD+ therapy using NMN and apigenin restoring muscle and bone in aged mice, meal timing linked to faster biological aging, and Vitamin C slowing iron-driven cellular senescence in primates. APOE4 was shown to make neurons hyperexcitable before Alzheimer's symptoms appear, while somatostatin overexpression reduced amyloid burden in mice. A single 30-minute sauna session triggered immune-boosting white blood cell mobilization. Suppressing the ghrelin receptor improved muscle function, and a potential treatment for post-operative delirium in older adults was identified. The roundup also covers Life Bio's FDA trial on resetting biological eye age, a potential landmark for mainstream longevity medicine.
