Blunted TLR3-induced inflammatory gene expression in the prefrontal cortex of the valproic acid model of autism, an effect unaltered by increasing endocannabinoid tone
Autism spectrum disorder (ASD) is associated with immune alterations and neuroinflammation. Increasing endocannabinoid tone attenuates ASD-related behavioural changes in rodent models and modulates Toll-like receptor (TLR)-induced neuro-immune responses. This study examined the effect of TLR3 activation, in the presence or absence of a fatty acid amide hydrolase (FAAH) inhibitor, on neuroinflammatory gene expression and endocannabinoid levels, in a preclinical rodent model of ASD. Female Sprague-Dawley rats prenatally exposed to either saline or valproic acid (VPA) received 1) the TLR3 agonist
