Maternal Immune Activation in a Genetic Mouse Model of ASD

Project: Research project

Project Details


? DESCRIPTION (provided by applicant): Autism spectrum disorder (ASD) is a diverse disorder that is likely to be caused by a combination of genetic alterations and environmental insult during early development. Studies demonstrate an association between maternal immune activation (MIA) during pregnancy and an increased risk for ASD. Recent development of mouse models for prenatal exposure to maternal immune activation (MIA) show that the challenged offspring demonstrate impaired behaviors relevant to ASD as well as exhibit altered levels of immune proteins. A significant gap exists in understanding how altered immune state interacts with ASD risk genes to result in impaired behaviors. Here we will test the hypothesis altered regulation of MHC1 proteins is a mechanism of convergence for MIA and ASD genetic risk factors. Specifically, we will examine how mutations in mecp2, a gene responsible for the Rett syndrome and also associated with non-Rett ASD cases, interact with MIA. We will, combine behavioral, molecular, electrophysiological and synaptic in vivo imaging analyses in relevant brain circuits to determine how altered Mecp2 levels and MIA converge to results in altered behavior and neuropathology.
