Figure 2: Expression of in striatum of Wt mice after 6-OHDA injection. (a) representative immunostaining in neurons and microglia in striatum. Immunostaining was carried out using antibodies for (shown in green) together with NeuN (top), OX42 (middle), and GFAP (bottom). Microglia, astrocytes, and neuronal markers are shown in red. In striatum, is expressed in neurons, microglial cells, and rarely with astrocytes. In (b), (c), and (d) the graphs represent the percentage of neurons, microglial cells and astrocytic cells expressing , respectively. ** (Wt saline versus Wt 6-OHDA).
