Scientists have discovered that an injection of particular blood molecules can replicate the benefits of exercise in the mind, paving the best way for potential new therapies for age-related cognitive decline in Alzheimer’s illness sufferers.
The study, revealed lately in the journal Nature Communications, discovered that platelets, the tiny blood cells vital for blood clotting, secrete a protein that rejuvenates neurons in aged mice in an identical technique to bodily exercise.
“We know exercise increases the production of new neurons in the hippocampus, the part of the brain important for learning and memory, but the mechanism hasn’t been clear,” stated Odette Leiter from the University of Queensland (UQ) in Australia.
“Our previous research has shown platelets are involved, but this study shows platelets are actually required for this effect in the aged mice,” Leiter stated in an announcement.
The study centered on exerkines, the organic compounds launched into the bloodstream throughout exercise, that are believed to stimulate the exercise-induced response in the mind.
“We discovered that the exerkine CXCL4/Platelet factor 4 or PF4, which is released from platelets after exercise, results in regenerative and cognitive improvements when injected into aged mice,” Leiter stated.
The findings have important implications for the event of drug interventions.

“For a lot of people with health conditions, mobility issues, or of advanced age, exercise isn’t possible, so pharmacological intervention is an important area of research,” stated Tara Walker from UQ’s Queensland Brain Institute.
“We can now target platelets to promote neurogenesis, enhance cognition and counteract age-related cognitive decline,” Walker stated.
The researchers stated the following step is to check the response in Alzheimer’s diseased mice, earlier than shifting in the direction of human trials.
“It’s important to note this is not a replacement for exercise. But it could help the very elderly or someone who has had a brain injury or stroke to improve cognition,” Walker stated.
