Interestingly, BLT1 blockade after the occurrence of lung metastases had no effect on the magnitude of lung metastasis, suggesting that inhibition of BLT1-mediated lung inflammation was insufficient to suppress established metastatic tumor.
Here, we developed a novel murine model of acute lung rejection to demonstrate that BLT1 controls effector CD8+ T cell trafficking into the lung and that disruption of BLT1 signaling in CD8+ T cells reduces lung inflammation and mortality in the model.
