Fig. 2From: Disruption of zinc transporter ZnT3 transcriptional activity and synaptic vesicular zinc in the brain of Huntington’s disease transgenic mouseElectron microscopic images of vesicular zinc in the striatum of TG mice. Zinc density in synaptic vesicles dramatically decreases in the striatum of the 20-week-old TG mice (b) compared to age-matched WT mice (a). Arrowheads show postsynaptic membrane. T1 axonal terminal containing AMG positive granules; T2 axonal terminal without AMG positive granules, d dendrite. Scale bars: 0.2 μmBack to article page
