DDT and edema: To test this effect, saline control, wt-MIF-2, and C-terminal variants of MIF-2 (R98A, I107A, G108A, K109A, and T112A) were delivered intratracheally into murine lungs, and the percentage of neutrophils and total protein (a marker for pulmonary edema) were measured from the bronchoalveolar lavage (BAL) fluid (Fig. 6).
