RESUMEN
Autism spectrum disorder (ASD) has been associated to atypical neuronal connectivity in the prefrontal cortex (PFC) and the hippocampus, in part, due to an alteration in neuroplasticity processes such as dendritic remodeling. Moreover, it has been proposed that abnormal cytoskeletal dynamics might be underlying the disrupted formation and morphology of dendrites in the ASD brain. Hence, we performed an analysis of the complexity of dendritic arborization of the pyramidal neurons localized in the layer II/III of the PFC and the CA1 region of the hippocampus in the autistic-like mouse strain C58/J, which has previously demonstrated neuronal cytoskeleton anomalies. We found differences in length, number and branching pattern of dendrites of the pyramidal neurons from both structures of C58/J strain. These data suggest a lower dendritic arborization complexity that could be involved with the characteristic autistic-like behaviors displayed in C58/J mice.
