Effects of Quorum Sensing Systems on Regulatory T Cells in Catheter-Related Pseudomonas aeruginosa Biofilm Infection Rat Models

<div>TGF-β1 immunohistochemical dyeing in lung tissues. TGF-β1 immunohistochemical dyeing in control group (a), PAO1 group (b), ΔlasIΔrhlI group (c), and ΔlasRΔrhlR group (d). Arrows indicate TGF-β1 protein, which was stained yellow and mainly localized in the cytoplasm and cell membrane of positive cells. DAB stain, original magnification, ×200.</div>
