Recent studies highlight the role of immune system dysfunction and inflammation in ASD pathophysiology. Indeed, elevated levels of pro-inflammatory cytokines were described in the brain and peripheral blood of ASD individuals. Despite this, how this pro-inflammatory profile evolves with aging and whether it may be associated with behavioral deficits is unknown. In this work, we explored the impact of aging on motor behavior and inflammation using Shank3b mutant mice, a model for syndromic ASD. <\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Using RT-qPCR and flow cytometry, we examined the expression of key pro-inflammatory molecules in the cerebellum, bone marrow, spleen, and peripheral blood, comparing adult and old <jats:italic>Shank3b<\/jats:italic><jats:sup>+\/+<\/jats:sup>, <jats:italic>Shank3b<\/jats:italic><jats:sup>+\/-<\/jats:sup>, and <jats:italic>Shank3b<\/jats:italic><jats:sup>-\/-<\/jats:sup> mice.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results and discussion<\/jats:title><jats:p>Our findings revealed genotype- and age-related differences in inflammation and motor behavior, with <jats:italic>Shank3b<jats:sup>-\/-<\/jats:sup><\/jats:italic> mice exhibiting accelerated aging and motor impairments.
