In a further test of a novel theory that suggests autism is the consequence of abnormal cell communication, researchers report that an almost century-old drug approved for treating sleeping sickness also restores normal cellular signaling in a mouse model of autism, reversing symptoms of the neurological disorder in animals that were the human biological age equivalent of 30 years old.
The researchers have tested the effect of suramin, a well-known inhibitor of purinergic signaling that was used to treat trypanosomiasis or African sleeping sickness, a parasitic disease. They found that suramin blocked the extracellular signaling pathway used by ATP and other mitokines in a mouse model of autism spectrum disorder (ASD), ending the cell danger response and related inflammation. Cells subsequently began behaving normally and autism-like behaviors and metabolism in the mice were corrected.
