dc.description.abstractBACKGROUND: Autism spectrum disorder involves neurodevelopmental dysregulations that lead to visible symptoms at early stages of life. Many autism spectrum disorder-related mechanisms suggested by animal studies are supported by demonstrated improvement in autistic-like phenotypes in adult animals following experimental reversal of dysregulated mechanisms. However, whether such mechanisms also act at earlier stages to cause autistic-like phenotypes is unclear. METHODS: We used Shank2(-/-) mice carrying a mutation identified in human autism spectrum disorder (exons 6 and 7 deletion) and combined electrophysiological and behavioral analyses to see whether early pathophysiology at pup stages is different from late pathophysiology at juvenile and adult stages and whether correcting early pathophysiology can normalize late pathophysiology and abnormal behaviors in juvenile and adult mice. RESULTS: Early correction of a dysregulated mechanism in young mice prevents manifestation of autistic-like social behaviors in adult mice. Shank2(-/-) mice, known to display N-methyl-D-aspartate receptor (NMDAR) hypofunction and autistic-like behaviors at postweaning stages after postnatal day 21 (P21), show the opposite synaptic phenotype-NMDAR hyperfunction-at an earlier preweaning stage (similar to P14). Moreover, this NMDAR hyperfunction at P14 rapidly shifts to NMDAR hypofunction after weaning (similar to P24). Chronic suppression of the early NMDAR hyperfunction by the NMDAR antagonist memantine (P7-P21) prevents NMDAR hypofunction and autistic-like social behaviors from manifesting at later stages (similar to P28 and P56). CONCLUSIONS: Early NMDAR hyperfunction leads to late NMDAR hypofunction and autistic-like social behaviors in Shank2(-/-) mice, and early correction of NMDAR dysfunction has the long-lasting effect of preventing autistic-like social behaviors from developing at later stages.-
