    … Describing a completely new theory for the origin and treatment of autism using APT, Naviaux and colleagues introduce the concept that a large majority of both genetic and environmental causes for autism act by producing a sustained cell danger response – the metabolic state underlying innate immunity and inflammation.

    “When cells are exposed to classical forms of dangers, such as a virus, infection or toxic environmental substance, a defense mechanism is activated,” Naviaux explained. “This results in changes to metabolism and gene expression, and reduces the communication between neighboring cells. Simply put, when cells stop talking to each other, children stop talking.”

    Since mitochondria – the so-called “power plants” of the cell – play a central role in both infectious and non-infectious cellular stress, innate immunity and inflammation, Naviaux and colleagues searched for a signaling system in the body that was both linked to mitochondria and critical for innate immunity. They found it in extracellular nucleotides like adenosine triphosphate (ATP) and other mitokines – signaling molecules made by distressed mitochondria. These mitokines have separate metabolic functions outside of the cell where they bind to and regulate receptors present on every cell of the body. Fifteen types of purinergic receptors are known to be stimulated by these extracellular nucleotides, and the receptors are known to control a broad range of biological characteristics with relevance to autism.

    The researchers tested suramin – a well-known inhibitor of purinergic signaling used medically for the treatment of African sleeping sickness since shortly after it was synthesized in 1916 – in mice. They found that this APT mediator corrected autism-like symptoms in the animal model, even if the treatment was started well after the onset of symptoms. The drug restored 17 types of multi-symptom abnormalities including normalizing brain synapse structure, cell-to-cell signaling, social behavior, motor coordination and normalizing mitochondrial metabolism.

    “The striking effectiveness shown in this study using APT to ‘reprogram’ the cell danger response and reduce inflammation showcases an opportunity to develop a completely new class of anti-inflammatory drugs to treat autism and several other disorders,” Naviaux said.
