Figure 6. Transmission electron microscopy of macrophages and microglial cells after 4 day feeding with HNE-modified ROSs. A: Electron micrograph of microglial cells after 4 day feeding with HNE-modified ROSs. Magnification: 6,000×. A higher magnification of the intracellular inclusion body region is presented in the micrograph below (magnification 26,000×). B: Electron micrograph of macrophages after 4 day feeding with HNE-modified ROSs. Magnification: 8,000×. A higher magnification of the intracellular inclusion body region is presented in the micrograph below (magnification 43,000×). White arrows indicate intracellular inclusion bodies in the higher magnification photographs in A and B.
