Figure Lengend Snippet: T lymphocyte proliferation evaluated by flow cytometry. ( A ) Percentage of CD3 + CD4 + cells; ( B ) Percentage of CD3 + CD8 + cells, from dogs fed control diet and experimental diet, that proliferated at least once when non-stimulated (None) or in response to recombinant antigen from Leptospira interrogans (LipL32) and concanavalin A (ConA). Bars correspond to mean plus standard error of the mean. * P < 0.05.

Article Snippet: The PBMC were washed with PBS and stained with anti-dog CD3 FITC-conjugate (Bio-Rad), anti-dog CD4 PE-Cy7-conjugate (eBioscience), and anti-dog CD25 Super Bright 436-conjugate (clone P4A10, 62-0250-42, eBioscience), protected from light, for 25 min at 4 °C.

Article Title: Cross-organ hierarchy of HLA molecular mismatches in donor-specific antibody development in solid organ transplantations

doi: 10.1016/j.xcrm.2025.102153

Figure Lengend Snippet: Examination of eplet mismatch immunogenicity in mixed lymphocyte reactions The association between the eplet risk score (ERS) and the activation status of responder CD4 + T cells was analyzed. Representative scattergrams are shown in (A), and aggregated scatterplots are shown in (B). Each stimulator-responder pair was analyzed with 3–6 biological replicates. The effect of an anti-55PP antibody (Ab) or an anti-45EV Ab on the percentage of CFSE low CD4 + T cells in the MLR was assessed using a stimulator-responder pair (pair #4, see ). Representative scattergrams are shown in (C), and aggregated data are shown in (D) and (E). Each antibody concentration group was analyzed with 4–12 biological replicates. ∗ p < 0.05. p values were determined using the Wilcoxon rank-sum test, which compared the value at 0 ng/mL Ab with those at 1 × 10 2 and 1 × 10 3 ng/mL Ab. EMn, the number of eplet mismatches; FSC, forward scatter; stim, stimulator. In the scatterplot shown in (B), large dots represent the median value of each stimulator-responder pair, small dots represent values obtained from each individual experiment, vertical lines represent ranges, and the gray area represents 95% confidence interval (CI) of the regression line. In the bar charts shown in (D) and (E), the top of the bar represents the median value, whereas the points represent values from individual experiments.

Data represents the mean ± SEM ( n = 10 birds/genetic line at baseline and n = 5/treatment of each genetic line at 6 hpi and 24 hpi). Note that the y-axis is larger in panels (B-E) . Different letter superscripts denote significant differences within a timepoint p ≤ 0.05.
