摘要
We show that following oral inoculation, prions bind to ileal Peyer patch and cecal patch microfold cells (M cells) in vivo. Furthermore, we show evidence that the cecum acts a biological sump holding large concentrations of prions for relatively long periods, thus increasing the exposure time of cecal patch M cells. Our results show a critical initial step in the translocation of prions from the intestinal lumen of mammals in vivo, which is a precursor to infection.
