FIG. 3.
Progressive accumulation of PrPd in the NALT of hamsters inoculated with HY TME. (A to D) Tissue sections that include depositions of PrPd in the NALT from hamsters at 4 weeks (A), 10 weeks (B), 16 weeks (C), and 22 weeks (D) after e.n. inoculation. Note the increased amount of PrPd immunoreactivity in the NALT at the various times postinfection. There is an increase in both the number of punctate deposits and the size of the deposits. The asterisk indicates the air space of the nasal cavity in each picture, and the arrow indicates a nerve fascicle (C). Bars, 50 μm.
