abstract = {Eosinophils are the principal effector cells for allergic inflammation in a variety of diseases, in which they contribute to tissue damage and remodelling processes via the secretion of cytotoxic granular proteins and cytokines. The intracellular mechanisms that control the activation, recruitment and survival of eosinophils are fundamental in understanding these disease processes. Phosphoinositide 3-kinase (PI3K) has been shown previously to be essential for eosinophil chemotactic responses to some stimuli but not others. Human blood neutrophils have been shown to utilize two antagonistic signalling pathways for chemotaxis: PI3K and p38 mitogen-activated protein kinase (p38 MAPK). In the present study, the role of p38 MAPK in chemotactic responses of an eosinophil-differentiated myeloid leukaemia cell line (EOL-1) and human peripheral blood eosinophils to a range of stimuli - platelet-activating factor (PAF), eotaxin 1 (CCL11), RANTES (CCL5), interleukin 8 (IL8, CXCL8) and IL16 - was explored through the use of the p38 MAPK α/β isoform inhibitor, SB 203580. SB 203580 caused significant inhibition of chemotactic responses of both EOL-1 cells and blood eosinophils to eotaxin 1 and RANTES (≥75% inhibition at 1 μM SB 203580, p},
