Longevity Genes: Immunity, DNA Repair & Lifespan in Mammals
Study links longevity in mammals to immunity genes & DNA repair. Gene duplication plays a role in lifespan variation. Research on resistance genes might lead to anti-aging therapies.
Fever’s link with a key kind of immunity is surprisingly ancient
In one fish species, Nile tilapia, that behavioral — or sought-out — fever triggers the adaptive immune system, known for its acquired memory of specific bodily invaders, researchers report in the Dec. 24 Proceedings of the National Academy of Sciences.
