Pancreatic and pulmonary mast cells activation during experimental acute pancreatitis

Figure 4 The effect of plasma on cultured mast cell line RBL-2H3 and alveolar macrophages. Mast cells were not activated by plasma from animals with pancreatitis. In contrast, the expression of tumor necrosis factor (TNF)α in alveolar macrophages was induced by plasma from animals with pancreatitis. This induction was not observed when animals were treated with cromolyn. ^aP < 0.05 vs C; ^cP < 0.05 vs AP. C: Control; AP: Acute pancreatitis.
