Ratio of PD-L1 to PECAM-1 expression in various tissues under control conditions and after IL-12-challenge. Under control conditions, the organs of the gastrointestinal tract were observed to three- to sixfold greater expression of PD-L1 than the lung and heart, as evidence of a greater PD-L1 to PECAM-1 ratio. After IL-12-challenge (72 hours), an invariance in PD-L1 expression was observed between tissues, suggesting that the peak expression of PD-L1 was not different among tissues. Values shown are means ± 95% confidence intervals.
