Expression of tight junction protein, occludin, was decreased in the brains of rabies-infected rats. Western blotting analyses of tight junction proteins, occludin and ZO-1, were shown in (A) the cerebral cortex and cerebellum. Relative levels of tight junction protein (B) occludin and (C) ZO-1 expression were determined by densitometric analysis. All samples analyzed (n = 4) were normalized to the intensity of corresponding β-actin bands. Results are expressed as mean ± SEM. *p < 0.05, significantly different from the control rats.
