What can lemurs tell us about inflammation and aging, aka “inflammaging” in humans?
What can lemurs tell us about inflammation and aging, aka “inflammaging” in humans? That’s the question Elaine Guevara, a biological anthropologist who studies the evolution of life history and aging in primates, set out to understand.
In newly published research on age-related inflammation in ring-tailed and sifaka lemurs, Guevara discovered that perhaps we should rethink the inevitability of inflammaging in humans.
Although similar in many ways, ring-tailed and sifaka lemurs show differences in life pacing and lifespan, making useful comparisons. Because lemurs and humans are primates and share a common ancestor that lived millions of years ago, they offer valuable insights into human evolution.
Her findings, she said, were “surprising.”
“Contrary to our predictions, neither species showed age-related change in either marker of oxidative stress. Neither lemur species exhibited age-related change in inflammation; if anything, contrary to our prediction, ring-tailed lemurs showed marginal declines in inflammation with age,” Guevara said.
