To further dissect the mechanism for the strong protective role of MyD88 during experimental melioidosis and in light of recent data suggesting that MyD88 is necessary for early neutrophil recruitment during hypersensitivity pneumonitis [32] as well as pulmonary infection with Pseudomonas aeruginosa[33], we investigated the role of MyD88 in neutrophil recruitment in our model. Here, MYD88 is linked to hypersensitivity pneumonitis.
