Effects of tetracycline on accumulation of PrPSc in the brain of scrapie-infected hamsters. Shown are PrP immunoblot analysis and immunohistochemistry of brain tissue of three hamsters (1–3) from the tetracycline-untreated (Upper) and tetracycline-treated (Lower) group with the antibody 3F4. The animals, randomly selected before infection, were injected intracerebrally with a 10−6 dilution of 263K scrapie-infected brain homogenate (Upper) or 263K scrapie-infected brain homogenate after incubation with tetracycline (Lower) and killed 90 days after inoculation (experiment 3).
