Figure Lengend Snippet: (A) Flow cytometric analysis of POD 16-tolerant and CLAD allografts with (A) representative contour plots gated on live CD45-allograft cells (N=5/group) and (B) Intracellular Sftpc expression analysis on CLAD allograft CD326+ αvβ6+ cells. The histogram shown is representative of three independent experiments. (C) Plot of POD 16 allograft numbers of live CD45-CD326+ αvβ6+ cells shown with a mean ± standard deviation from the mean for N=5 per group. Representative immunohistochemical stains with αvβ6 specific antibodies with indicated magnification and scales (N≥4/group).

Article Snippet: Sections were then stained with 1:200 αvβ6 antibodies (bs-5791R, Bioss for mouse tissue; AB00891-23.0, Absolute Antibody for human tissue) overnight at 4°C.

Techniques: Expressing, Standard Deviation, Immunohistochemical staining

Figure Lengend Snippet: αvβ6 immunohistological staining of allografts from recipients that underwent club cell injury and received (A) CCL2 neutralizing Abs, (B) CD8α depleting Abs, respectively, and (A, B) Control Ig injections followed by POD 16 [ 64 Cu]Cu-DOTA-A20-K16R PET/CT imaging. Images shown are representative of N≥4 per group. Scale bars: 400 μm for 10x, 100 μm for 40x.

Figure Lengend Snippet: (A, Left Panel) Representative autoradiographic images following incubation of [ 64 Cu]Cu-DOTA-A20-K16R with human explanted lung tissue sections from a patient with CLAD and Control lung tissue from a donor lung obtained prior to transplantation. Preincubation with an excess of a cold probe sharply reduces autoradiographic activity (Cold Probe/CLAD). (A, Right Panel) corresponding trichrome-stained lung sections that were incubated with radiotracer. Images are representative of independently conducted experiments, with (B) violin plots showing combined data from 3 explanted CLAD transplants with or without cold-probe blockade and 3 control lungs per group. Two-sided Mann-Whitney U t-test *p<0.05, ***p<0.001. Representative αvβ6 (C) immunohistochemical and (D) immunofluorescent staining of human explanted lungs with CLAD and control lungs (N=3/group). Arrows denote clusters of cells expressing αvβ6. Scale bars: 400 μm for 10x, 100 μm for 40x.

Article Snippet: Sections were then stained with 1:200 αvβ6 antibodies (bs-5791R, Bioss for mouse tissue; AB00891-23.0, Absolute Antibody for human tissue) overnight at 4°C.
