Research and Practice Interests

Most research to date has focused on transcriptional, epigenetic, electrophysiological and morphological adaptations within neurons to understand drug addiction and relapse. Instead, Dr. Kruyer and her lab use single cell approaches to characterize astroglial subpopulations within the basal ganglia, the collection of brain nuclei that orchestrate motivated behaviors, including drug seeking. The principal findings of this work demonstrate a dynamic role for astrocytes in suppression of relapse-like behavior through regulation of synaptic activity in multiple basal ganglia nuclei. The ultimate goal of this research is to identify druggable targets that can be targeted to restore synaptic homeostasis and reduce relapse rates in patients with substance use disorder and in other vulnerable populations.
