ACTB and autism: The levels of recognized indicators of inflammatory processes in brain tissue, including Aquaporin 4 and Connexin 43 were examined in the brains of those with an autism diagnosis. The study found that, in contract to controls, in evaluations using the brain’s β-actin level as a reference, Aquaporin 4 expression was decreased significantly in cerebellum, while, in Brodmann’s area 9 (superior frontal cortex), Connexin 43 was elevated in the brains of those diagnosed with autism.
