Involvement of LPF to promote interaction between AIEC LF82 bacteria and PPs.
(A) Quantification of intra-human PP-associated bacteria by confocal microscopy. Each value is the mean ± SEM of 2–4 separate experiments, with 3–5 sections studied for each experiment. **P < 0.01. (B) Representative confocal photomicrographs of uptake of bacteria across human FAE. Scale bars: 100 μm for HES staining and 50 μm for confocal analysis. Images in the bottom row correspond to the boxed regions in the top row. See the Figure 1D legend for staining.
