abstract = {Synaptic dysfunction is a key feature of SHANK-associated
disorders such as autism spectrum disorder, schizophrenia,
and Phelan-McDermid syndrome. Since detailed knowledge of
their effect on synaptic nanostructure remains limited, we
aimed to investigate such alterations in ex11|SH3 SHANK3-KO
mice combining expansion and STED microscopy. This enabled
high-resolution imaging of mosaic-like arrangements formed
by synaptic proteins in both human and murine brain tissue.
We found distinct shape-profiles as fingerprints of the
murine postsynaptic scaffold across brain regions and
genotypes, as well as alterations in the spatial and
molecular organization of subsynaptic domains under
SHANK3-deficient conditions. These results provide insights
into synaptic nanostructure in situ and advance our
understanding of molecular mechanisms underlying synaptic
dysfunction in neuropsychiatric disorders.},
