Dietary and gastrointestinal factors may contribute to the etiology of autism spectrum disorders (ASD). Propionic acid (PPA) is a short chain fatty acid that is an intermediary of fatty acid metabolism and a fermentation by-product of enteric bacteria. Using a single infusion (Chapter 2) and repeated infusions (Chapter 3), the temporal relationship between PPA-induced locomotor activity and astrocyte/microglial changes was demonstrated. Adult Long-Evans rats were centrally infused with 4µl of 0.26M PPA or 0.1M PBS vehicle once or once a week for four weeks. Locomotor activity was evaluated for 20 minutes following infusion and again several days later to assess …
