A schizophrenia-associated radial glia cell state perturbs early human brain development

Susmita Malwade, Samudyata Samudyata, Jessica Gracias Lekander, Angelika Langeder, Katharina Weinberger, Marja Koskuvi, Ana Osório Oliveira, Šárka Lehtonen, Luis Enrique Arroyo‐García, Aiden Peter Corvin, Sarah E. Bergen, Ilkka Ojansuu, Olli Vaurio, Jari Koıstınaho, Jari Tiihonen, Carl M. Sellgren

This study identifies a schizophrenia-associated radial glia cell state that disrupts early human brain development through single-cell transcriptomic and epigenomic analyses of organoids.

Patient iPSC-astrocytes show transcriptional and functional dysregulation in schizophrenia

Marja Koskuvi, Šárka Lehtonen, Kalevi Trontti, Meike Hedwig Keuters, Ying Chieh Wu, Hennariikka Koivisto, Anastasia Ludwig, L. M. Plotnikova, Pekka L. J. Virtanen, Noora Räsänen, Satu Kaipainen, Ida Hyötyläinen, Hiramani Dhungana, Raisa Giniatullina, Ilkka Ojansuu, , Jari Koıstınaho

The paper shows that astrocytes from schizophrenia patients exhibit transcriptional and functional changes, including inflammation and synaptic pathway alterations, which are partially reversible with clozapine treatment.
