The Autism Rat Consortium (ARC) seeks to capitalize on the rat as an experimental system to advance our understanding of the behavioral and circuit neuroscience mechanisms underlying autism and related neurodevelopmental disorders. The ARC was established in 2022 following an RFA that funded investigators (see ARC 1.0, below) to use SFARI rat models with CRISPR/Cas9-induced loss of function of high-confidence autism risk genes to study behaviors and circuits relevant to autism. The SFARI rat models were generated at the Medical College of Wisconsin and are available to all researchers at minimal cost. Rats are larger than mice (making it more feasible to study early developmental time points), are more easily trained on complex behavioral tasks, and have a richer social behavior repertoire. The SFARI rat lines were also generated on an outbred genetic background, making it possible to study gene penetrance and individual variability. These rat lines are also being behaviorally characterized at the Simons Initiative for the Developing Brain (SIDB) in Edinburgh, Scotland. This year, SFARI held a second RFA which funded 8 projects involving 16 investigators. ARC members are working collaboratively to study the behavior and neurophysiology underlying social interaction (including play behavior), sensory processing, navigation, and learning & memory. The consortium holds regular meetings and shares data and protocols among members.
