University of Queensland researchers have discovered that injecting platelets, the blood cells responsible for blood clotting, secretes a protein that rejuvenates neurons in aged mice in a similar way to physical exercise.

Stimulating neuron production in the brain

This “platelet factor 4” protein could help the very elderly (or someone who has had a brain injury or stroke) improve cognition, said Dr. Odette Leiter, at UQ’s Queensland Brain Institute. The researchers plan to test this response in Alzheimer-diseased mice, before moving towards human trials. If successful, the study could lead to drug interventions.
