Cerebellar astrocytic alterations in depression.

ABSTRACT: Accumulating evidence suggests dysfunction of cerebellar-cerebral circuits in depression. However, the potential cellular and molecular alterations associated with depression in the cerebellum remain largely uncharacterized. While postmortem findings in the cerebral cortex indicate astrocyte dysregulation in depressed individuals who died by suicide (DS), the extent to which depression potentially alters cerebellar astrocytes is not well understood. In this study, two canonical astrocyte markers, glial fibrillary acidic protein (GFAP) and aldehyde Dehydrogenase-1 Family member L1 (ALDH1L1) were used to quantify cerebellar astrocyte subtypes, Bergmann glia (BG) in the Purkinje cell layer (PCL), velate astrocytes in the granule cell layer (GCL), and fibrous astrocytes in the white matter (WM
