    • Longitudinal Transcriptomic Analysis of Human Cortical Spheroids Identifies Axonal Dysregulation in the Prenatal Brain as a Mediator of Genetic Risk for Schizophrenia 

      Akkouh, Ibrahim Ahmed; Ueland, Thor; Szabo, Attila; Hughes, Timothy; Smeland, Olav Bjerkehagen; Andreassen, Ole; Requena Osete, Jordi; Djurovic, Srdjan (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-09-03)
      BACKGROUND: Schizophrenia (SCZ) has a known neurodevelopmental etiology, but limited access to human prenatal brain tissue hampers the investigation of basic disease mechanisms in early brain development. Here, we elucidate the molecular mechanisms contributing to SCZ risk in a disease-relevant model of the prenatal human brain.<p> <p>METHODS: We generated induced pluripotent stem cell–derived ...

      A large fraction of genetic risk factors for Alzheimer’s Disease (AD) is still not identified, limiting the understanding of AD pathology and study of therapeutic targets. We conducted a genome-wide association study (GWAS) of AD cases and controls of European descent from the multi-center DemGene network across Norway and two independent European cohorts. In a two-stage process, we first performed ...
