• Granzyme B is an enzyme, but more specifically it’s a serine protease. That means it’s capable of breaking down other proteins
  • To test their hypothesis, the team did another experiment with the same type of engineered mice lacking Granzyme B. The mice were exposed to a few minutes of UV light
  • After 20 weeks, the mice without Granzyme B still had pristine, wrinkle-free skin, whereas the control group was starting to show wrinkles.
