Interleukin-3, -5, and granulocyte macrophage colony-stimulating factor-induced adhesion molecule expression on eosinophils by p38 mitogen-activated protein kinase and nuclear factor-[kappa] B.

We investigated the intracellular signaling mechanisms for cytokine interleukin (IL)-3, IL-5, or granulocyte-macrophage colony-stimulating factor (GM-CSF)-induced expression of adhesion molecules including very late antigen 4 (CD49 d), macrophage antigen-1 (CD11b), leukocyte function-associated antigen-1 (CD11a/CD18), intercellular adhesion molecule (ICAM)-1, and ICAM-3 on eosinophils. The expression of adhesion molecules and nuclear factor (NF)-kappaB pathway was measured by flow cytometry and cDNA expression array, respectively. The phosphorylation of inhibitor kappaB-alpha and p38 mitogen- activated protein kinase ( MAPK) was detected by Western blot, whereas NF-kappaB activity was measured by electrophoretic mobility shift assay. IL-3, IL-5, and GM-CSF could enhance p38 MAPK and NF-kappaB activity and induce ICAM-1, CD11b, and CD18 expressions on eosinophils. They could suppress ICAM-3 expression, but had no effect on CD49 d expression. Either SB 203580 or MG-132 was able to offset the cytokine-induced expression of ICAM-1. Only SB 203580 could reverse the effect on CD11b, CD18, and ICAM-3 expressions. Therefore, the expression of ICAM-1 might involve both p38 MAPK and NF-kappaB activities, whereas the regulation of CD11b, CD18, and ICAM-3 expressions might be mediated through p38 MAPK but not NF-kappaB. These cytokines therefore play a crucial role, via the p38 MAPK and NF-kappaB pathways, in the expression of important adhesion molecules on eosinophils in allergic inflammation.[1]
