FIGURE 5

Multiple label immunofluorescence of mGlu3 labeling in microglia in layer II/III of rat PL mPFC. Tissue was labeled with antibodies recognizing the microglial protein Iba1 (cyan), mGlu3 (red), the dendritic marker Map2 (green), as well as the nuclear Hoechst stain (blue). (A) There are diffuse Iba1 positive microglial processes across the neuropil in layer III. (Ai–iv) Magnified area of the yellow box in (A), showing an Iba1 positive microglial process (cyan) co-localized with mGlu3 (red), indicated by white arrows. Scale bars: 10 μm (A), 2.5 μm (Ai–iv).
