Bat DNA reveals longevity linked to immune function and cell death strategy

Researchers at UC Berkeley and Penn State analyzed genomes of long-lived Myotis bats, finding that their longevity is tied to immune genes that fight cancer and a strategy of killing damaged cells rather than repairing them. The study suggests that understanding bat immunity could inform human aging and disease prevention.

Bottom line — The study identifies specific genetic overlaps between bat longevity and viral interaction genes, pointing to immune system evolution as a key to extended lifespan.

  • The longest-lived bat, the little brown bat, prioritizes cell death over DNA repair when exposed to toxins, per the study published in Nature.
  • Bats have unusually high immune activity, allowing them to host many viruses without getting sick, according to researchers.
  • There is significant overlap between genes associated with bat lifespan and those involved in bat-virus interactions, said lead author Juan Manuel Vazquez.
  • The mismatch between bat and human immune defenses may explain why bat-borne viruses are dangerous to humans, Vazquez argued.
  • The study analyzed eight Myotis genomes, including Brandt's myotis which can live up to 50 years, per the paper.
