IFN-γ signaling links ventriculomegaly to choroid plexus and ependyma dysfunction following maternal immune activation.

J Neuroinflammation

March 2025

Neuroprotective Drug Discovery Key Laboratory, Jiangsu Key Laboratory of Neurodegeneration, State key laboratory of reproductive medicine and offspring health, Nanjing Medical University, Nanjing, Jiangsu, 211166, China.

Maternal immune activation (MIA) is a principal environmental risk factor contributing to autism spectrum disorder (ASD) and can be causally linked to ASD symptoms. In our study, we found that MIA triggered by poly (I: C) injection caused ventriculomegaly in offspring due to the dysfunction of the choroid plexus (Chp) and ependyma. We subsequently identified a sustained enhancement of interferon-γ (IFN-γ) signaling in the brain and serum of MIA offspring.

Mutations or deletions in the SHANK3 gene have been identified in up to 1% of autism spectrum disorder cases and are considered the primary cause of neuropsychiatric symptoms in Phelan McDermid syndrome (PMS). While synaptic dysfunctions have been extensively documented in the absence of Shank3, other mechanisms through which Shank3 may regulate neuronal functions remain unclear. In this study, we report that the ribosomal protein Rpl3 and overall protein synthesis are downregulated in the cortex and striatum of Shank3 knockout (KO) mice and in neurons differentiated from human-induced pluripotent stem cells (hiPSCs) derived from a PMS patient.

The Enteric Nervous System (ENS), often called the "second brain," is a complex network of neurons and glial cells within the gastrointestinal (GI) tract. It functions autonomously while maintaining close communication with the central nervous system (CNS) via the gut-brain axis (GBA). ENS dysfunction plays a crucial role in neurodegenerative and neurodevelopmental disorders, including Parkinson's disease, Alzheimer's disease, and autism spectrum disorder.

Deep learning for Electroencephalography (EEG) has become dominant in the tasks of discrimination and evaluation of brain disorders. However, despite its significant successes, this approach has long been facing challenges due to the limited availability of labeled samples and the individuality of subjects, particularly in complex scenarios such as Autism Spectrum Disorders (ASD). To facilitate the efficient optimization of EEG discrimination models in the face of these limitations, this study has developed a framework called STEM (Self-Training EEG Model).

Autism spectrum disorder (ASD) is a neurodevelopmental disorder that affects nearly 3% of children and has a strong genetic component. While hundreds of ASD risk genes have been identified through sequencing studies, the genetic heterogeneity of ASD makes identifying additional risk genes using these methods challenging. To predict candidate ASD risk genes, we developed a simple machine learning model, ASiDentify (ASiD), using human genomic, RNA- and protein-based features.

Purpose: The purpose of this retrospective cohort analysis was to investigate sex differences in receipt of standard of care sleep and constipation drug treatments among autistic children and youth with sleep disorder and constipation, respectively.

Methods: We used the data from the OneFlorida + Data Trust to analyze healthcare claims for 19,877 autistic patients with sleep disorder and 32,355 patients with constipation, ages 1 to 22. We used logistic regression to examine sex differences in receiving sleep and constipation treatments, and a multivariate logistic regression model to further assess sex differences in ever receiving sleep and constipation treatments, adjusting for age, race, ethnicity, and urbanicity.

Using games as part of the intervention and support process (sometimes referred to as 'gaming therapy') is an increasingly popular method of supporting autistic youth to develop social competencies and other skills because they are believed to be inherently motivating and fun for youth. Some emerging research has indicated that intervention programmes using games can be beneficial for autistic youth, but little is currently known about why, how and for whom they work. This study conducted a realist evaluation of a programme using the video game "Minecraft" for autistic youth, comprising interviews and observations with autistic youth ( = 4), facilitators ( = 2) and caregivers ( = 6).

Prior research has shown conflicting findings on decision-making differences between autistic and non-autistic individuals. To address this issue, we applied the Ultimatum and Dictator Games to examine explicit measures (probability of endorsing monetary offers) and implicit measures (response times) associated with decision-making behaviors. By analyzing response times, we aimed to determine whether decisions were intuitive (rapid) or deliberative (slower) reasoning processes.

Neurexins are presynaptic plasma membrane proteins that regulate key aspects of synapse physiology through the formation of transcellular complexes with postsynaptic ligands, including neuroligins (Nlgns). Each neurexin gene (NRXN1-3) generates two main alternative-spliced transcripts that generate alpha and beta-Nrxn isoforms differing in their extracellular domains. Mutations in NRXN1 are associated with autism and other neurodevelopmental disorders.

Disrupted visual attention relates to cognitive development in infants with Neurofibromatosis Type 1.

J Neurodev Disord

March 2025

Centre for Brain and Cognitive Development, School of Psychological Sciences, Faculty of Science, Henry Wellcome Building, Birkbeck, University of London, Malet Street, London, UK.

Background: Neurofibromatosis Type 1 is a genetic condition diagnosed in infancy that substantially increases the likelihood of a child experiencing cognitive and developmental difficulties, including Autism Spectrum Disorder (ASD) and Attention Deficit Hyperactivity Disorder (ADHD). Children with NF1 show clear differences in attention, but whether these differences emerge in early development and how they relate to broader difficulties with cognitive and learning skills is unclear. To address this question requires longitudinal prospective studies from infancy, where the relation between domains of visual attention (including exogenous and endogenous shifting) and cognitive development can be mapped over time.
