How platelets can replicate advantages of train in mind: Study

Researchers on the University of Queensland revealed in pre-clinical research that an injection of a certain blood factor can duplicate the constructive results of train on the mind.

Using previous mice as a mannequin, a group lead by Dr. Odette Leiter and Dr. Tara Walker from the University of Queensland’s Queensland Brain Institute revealed that platelets, the tiny blood cells important for blood clotting, launch a protein that rejuvenates neurons in a fashion corresponding to bodily exercise.

“We know exercise increases production of new neurons in the hippocampus, the part of the brain important for learning and memory, but the mechanism hasn’t been clear,” Dr Leiter stated.

“Our previous research has shown platelets are involved, but this study shows platelets are actually required for this effect in the aged mice.”

The researchers centered on exerkines, the organic compounds launched into the bloodstream throughout train, that are believed to stimulate the exercise-induced response within 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,” Dr Leiter stated.

Dr Walker 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,” she stated.

“We can now target platelets to promote neurogenesis, enhance cognition and counteract age-related cognitive decline.”

The researchers stated the following step is to check the response in Alzheimer diseased mice, earlier than shifting in direction of human trials.

“It’s important to note this is not a replacement for exercise,” Dr Walker stated.

“But it could help the very elderly or someone who has had a brain injury or stroke to improve cognition.”
