This piece previews a neuroscience research article exploring how activity of a specific brain enzyme may support cognitive resilience with age. It invites readers to learn about experimental and human-data approaches used to investigate links between the enzyme, brain health, and memory.

Memory stays strong in old age when this brain enzyme is active
Key Takeaways
  • Pla2g2f loss in mice caused increased brain inflammation and accelerated neuron degradation with age.
  • Overexpression of Pla2g2f in mice reduced inflammation and preserved neuronal connectivity and spatial memory.
  • Higher PLA2G2F activity was observed in human donors who remained cognitively resilient despite amyloid-β brain deposits.
