Indeed, GFAP and GLT1—both astroglial markers—correlated with sucrose consumption measures, suggesting a link with anhedonia-like phenotype, while SYN1 levels and GPHN levels –synaptic and GABAergic markers, respectively—correlated with residual avoidance in the shelter, suggesting a link with anxiety-like phenotype. The gene discussed is SLC1A2; the disease is Anxiety.
