Granzyme B

From Longevity Wiki

Granzymes, a family of serine proteases with intracellular cytotoxic and/or proinflammatory functions, are increasingly recognized for their emerging roles in biological aging and disease. Widely recognized as intracellular mediators of cell death, granzymes, particularly granzyme B (GzmB) is observed in numerous age-related conditions, also accumulate in the extracellular milieu of tissues with age, contributing to chronic tissue injury, inflammation, and impaired healing. Genetic deletion and/or pharmacological inhibition of granzyme B reduces premature aging and/or disease phenotypes in animal models.[1]
