Fig. 2From: Memory retrieval in addiction: a role for miR-105-mediated regulation of D1 receptors in mPFC neurons projecting to the basolateral amygdalaEffect of chronic morphine on D1 receptor expression in glutamatergic projection neurons from the hippocampus and the thalamus to the BLA using triple-immunofluorescence method. a Panel 1: the averaged optical density of D1R; panel 2: BDA- and VGLUT2-labeled axon terminals; panel 3: triple labeling clusters in saline and morphine groups (n = 9, *P < 0.05, compared to saline group). b The averaged optical density of D1R (panel 1), BDA-labeled axon terminals (panel 2), VGLUT2 (panel 3), and triple labeling clusters in saline and morphine groups (3) (n = 6, *P < 0.05, compared to saline group). Data are shown as the mean ± SEMBack to article page
