Ultra-rare coding variants in schizophrenia risk genes are associated with longitudinal phenotypic differences across psychotic disorders

Anders J. Kämpe, Julia Sealock, Evan Jeffrey Giangrande…·Olli P. H. Pietiläinen

This study identifies ultra-rare damaging variants in schizophrenia risk genes and shows they are associated with earlier hospitalizations, greater childhood adversity, and poorer neuropsychological outcomes across psychotic disorders.

Astrocytic-supplied cholesterol drives synaptic gene expression programs in developing neurons and downstream astrocytic transcriptional programs

Emilia Vartiainen, Dhara Liyanage, Illinca Mazureac…·Olli P. H. Pietiläinen

The paper shows that astrocyte-supplied cholesterol drives synaptic gene expression in neurons and induces astrocytic transcriptional responses, linking lipid metabolism to neurodevelopmental disorders.

Astrocytic cell adhesion genes linked to schizophrenia correlate with synaptic programs in neurons

Olli P. H. Pietiläinen, Aditi Trehan, Daniel Meyer…·Ralda Nehme

The paper shows that astrocyte-neuron interactions enhance synaptic gene expression in neurons and correlate with schizophrenia risk genes.
