Representative immunofluorescent images of the microglia and virus in the motor cortex in mock and VEEV TC-83 inoculated mice at 6 dpi. Sagittal sections of the brain were stained with Iba-1 (green), VEEV TC-83 (red), and nuclei (blue). (A) Representative image of motor cortex shows layers I and II from a mock-inoculated mouse brain. Microglia were present with fine, long processes with round or elongated cell nuclear distributed in brain tissues. (B) Representative image of motor cortex shows soma and processes of infected neurons (red) near microglia cells. Activated microglia were thick with short process. Scale bar = 50 µm.
