Abstract

Chemoattractants and chemokines, such as interleukin 8 (IL-8), are defined by their ability to induce directed cell migration of responsive cells. The signal transduction pathway(s) leading to cell migration remain ill defined. We demonstrate that phosphatidylinositol-3-kinase (PI3K) activity, as determined by inhibition using wortmannin and LY294002, is required for IL-8-induced cell migration of human neutrophils. Recently we reported that IL-8 caused the activation of the Ras/Raf/extracellular signal-regulated kinase (ERK) pathway in human neutrophils and that this activation was dependent on PI3K activity. The regulation of cell migration by IL-8 is independent of ERK kinase and ERK activation since the ERK kinase inhibitor PD098059 had no effect on IL-8-induced cell migration of human neutrophils. Additionally, activation of p38-mitogen-activated protein kinase is insufficient and activation of c-Jun N-terminal kinase is unnecessary to induce cell migration of human neutrophils. Therefore, regulation of neutrophil migration appears to be largely independent of the activation of the mitogen-activated protein kinases. The data argue that PI3K activity plays a central role in multiple signal transduction pathways within the human neutrophil leading to distinct cell functions.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
