Extracellular vesicles from stem cells rescue cellular phenotypes and behavioral deficits in SHANK3-associated ASD neuronal and mouse models.

Cell death &amp; disease2026 Feb 22

Extracellular vesicles (EVs) are lipid bilayer-enclosed structures that mediate intercellular communication by transferring diverse cargoes, including RNA and proteins. SHANK3, a synaptic scaffolding protein critical for synapse structure and function, is implicated in autism spectrum disorder (ASD) and Phelan-McDermid Syndrome (PMS). Early hyperexcitability in cortical neurons is a characterized endophenotype in ASD. Here, we investigated EV-mediated effects in the context of SHANK3 deficiency using human iPSC-derived cortical neurons and Shank3B-/- mice. Switching EVs between SHANK3 mutant and control neurons revealed that SHANK3 mutant-derived EVs transferred the hyperexcitability and accelerated maturation phenotypes to control neurons. Proteomic analysis revealed enrichment of synaptic structural regulators (e.g., ACTB, CFL1, AGRN, and CLSTN1) in SHANK3 mutant neuron-derived EVs. This is consistent with known actin cytoskeletal dysregulation driven by SHANK3 deficiency. However, control neuron-derived EVs failed to rescue mutant phenotypes, likely due to their decreased enrichment of synaptic proteins and related pathways. Further, EVs from mesenchymal stem cells (MSCs) and healthy donor iPSCs, containing synaptic modulators such as complement proteins (C1R, C1S), plasticity-associated proteins (MDK, IGFBP3), and homeostatic regulators (FGF2, SFRP1), rescued the hyperexcitability and normalized the maturation in SHANK3 mutant neurons. In addition, intranasal administration of iPSC-derived EVs in Shank3B-/- mice significantly rescued ASD-like behavioral deficits, emphasizing their therapeutic potential. Together, these findings reveal a novel EV-mediated mechanism for modulating dysregulated excitability and synaptic maturation, addressing a critical unmet need in ASD and associated neurodevelopmental disorders.

Craniofacial Dysmorphology Associated With Phelan-McDermid Syndrome Using Three-Dimensional Morphometrics.

Clinical genetics2026 Feb 18

Phelan-McDermid syndrome (PMS) frequently presents with distinctive facial features, although a typical facial phenotype for this condition has not been well characterized. Facial dysmorphology assessments can be subjective, depending on the experience and training of the clinical geneticist conducting the patient evaluation. In this investigation, we sought to quantitatively assess craniofacial features in Phelan-McDermid syndrome. Three-dimension (3D) morphometric assessment was conducted of 100 children and young adults diagnosed with PMS and 536 age- and sex-matched typically developing subjects obtained from the FaceBase consortium. The data were analyzed using principal component analysis (PCA), Procrustes MANOVA, and canonical variates analysis (CVA). We found that people with PMS aged 3-32 years have quantitatively distinctive craniofacial features compared to age- and sex-matched normed people. We observed an elongated face, a pointed chin, a flattened midface, and nasal expansion as characteristic of the PMS facial phenotype. Further, distinct growth patterns were observed, with children ages 3-6 and 7-12 years having more rapid growth compared to matched normed samples. While people with PMS have distinctive facial features, individual variation is the greatest contribution to facial variation. Quantitative assessment of craniofacial features paired with genotype can further our understanding of genetic contributions to craniofacial development.

Neurophysiological Profiles in a Family with Multiple SHANK3-Related Phelan-McDermid Syndrome Cases.

International journal of molecular sciences2026 Feb 05

We present a family case study of Phelan-McDermid syndrome (PMS), a neurodevelopmental disorder caused by haploinsufficiency of the SHANK3 gene, in which two of three siblings were clinically diagnosed with PMS. Sanger sequencing identified a novel heterozygous deletion in exon 20 of SHANK3 (c.3679del, p.Ala1227Profs*168), predicted to introduce a premature stop codon and truncate the protein; this variant was absent in the unaffected sibling. Auditory steady-state responses (ASSRs) were recorded at 16, 27, and 40 Hz. The 40 Hz ASSR was markedly reduced in both affected siblings, reaching statistical significance in the younger child and remaining non-significant in the older sibling, while it was preserved in the unaffected sibling. These findings suggest that the 40 Hz ASSR is particularly sensitive to SHANK3-related cortical inhibitory dysfunction during childhood and adolescence, with reduced sensitivity in early adulthood. The results highlight the potential of the 40 Hz ASSR as an electrophysiological biomarker in PMS and underscore the need for age-stratified normative control datasets to enable robust individual-level interpretation and support its use in biomarker development, clinical trial stratification, and monitoring of treatment response.

A human electrophysiological signature of Fragile X pathophysiology is shared in V1 of Fmr1-/y mice.

Nature communications2026 Feb 09

Predicting clinical therapeutic outcomes from animal studies using conserved electrophysiological phenotypes could facilitate developing treatments for neuropsychiatric disorders. Alpha oscillations in human resting-state electroencephalogram recordings are altered in many disorders, but whether these disruptions exist in mouse models is unknown. Here, we employed a uniform analytical method to show in males with fragile X syndrome (FXS) that alpha oscillations in humans and alpha-like oscillations in the visual cortex of Fmr1-/y mice are slowed, with a stronger phenotype in adults than juveniles and a juvenile-specific power phenotype in both species. We find that alpha-like oscillations are disrupted by deletion of Fmr1 in cortical excitatory neurons and glia, reflect differential activity of two classes of GABAergic interneurons, and are more sensitive to activation of GABAB receptors by Arbaclofen in wild-type than Fmr1-/y mice. Our framework reveals evolutionary conservation of alpha oscillation disruptions, enables a deeper understanding of FXS pathophysiology, and narrows the gap between treatment promise and practice.

Altered Structural Plasticity Mediated by mGlu and NMDA Receptors and Impaired Cognition in a Genetic ASD Model (Shank3+/- Mice).

The Journal of neuroscience : the official journal of the Society for Neuroscience2026 Feb 04

Dendritic spine morphology is strongly associated with neurodevelopmental disorders. Synaptic plasticity alters spine volume, a phenomenon known as structural plasticity, which influences information processing within neuronal circuits. Structural changes at dendritic spines are linked to autism spectrum disorders, particularly those involving gene mutations that result in synaptopathy. Loss of a single copy of the Shank3 gene leads to Phelan-McDermid syndrome, a synaptopathy, as Shank3 encodes SHANK3, a scaffold protein in the postsynaptic density of glutamatergic neurons. In this study, the structural plasticity of dendritic spines was evaluated in male and female Shank3+/- and wild-type mice in response to synaptic plasticity. Two-photon imaging and glutamate uncaging were employed in organotypic hippocampal cultures. Cognitive function in adult Shank3+/- mice was also assessed using a novel object recognition test. The results indicate that Shank3+/- mice exhibit altered structural plasticity in response to long-term depression and display a heterosynaptic response in neighboring spines. Increased GluN2B expression and N-methyl-d-aspartate currents underlie these effects and may influence object recognition memory in Shank3+/- mice. These findings suggest that Shank3 haploinsufficiency induces synaptic alterations during postnatal development that impact memory in adulthood.
