Rescue strategy | Nature Reviews Neuroscience

Access through your institution Buy or subscribe Mutations in SH3 and multiple ankyrin repeat domains protein 3 (_SHANK3_) are associated with several neurodevelopmental disorders, but it is

not known whether correcting SHANK3 levels in the mature CNS would alleviate synaptic impairments in rodents carrying _Shank3_ mutations. Mei _et al_. generated a mouse, lacking

constitutive expression of _Shank3_, in which the gene could be conditionally knocked-in at specific time points. Knock-in of _Shank3_ in these mice during adulthood restored levels of

synaptic proteins and corrected physiological impairments in striatal neurons, and rescued impairments in social behaviour. In a different approach, Bidinosti _et al_. characterized the

dysregulation of phosphoprotein expression that occurs in rat cortical neurons that lack _Shank3_ and showed that the expression of CDC-like kinase 2 (CLK2) was upregulated in these cells.

Pharmacological inhibition of CLK2 corrected synaptic deficits in brain slices from adult mice carrying a mutation in exon 21 of _Shank3_ and rescued impairments in social behaviour in these

mice. Together, these findings suggest that adulthood restoration of SHANK3 levels, or restoration of downstream mediators, may be a useful strategy to alleviate some of the synaptic and

behavioural impairments associated with _SHANK3_ mutations. This is a preview of subscription content, access via your institution ACCESS OPTIONS Access through your institution Subscribe to
