- Abstract:
The YadA protein of Yersinia pseudotuberculosis promotes tight adhesion and invasion into mammalian cells through beta(1)-integrins. In this work, we demonstrate that YadA also triggers the production of interleukin-8 (IL-8) in host cells and we identify intracellular signal transduction mechanisms involved in YadA-initiated cell invasion and/or IL-8 synthesis. Tyrosine protein kinases, including the focal adhesion kinase (FAK) and c-Src, as well as the small GTPase Ras, were shown to play a significant role in both YadA-promoted cell processes. YadA-mediated cell contact led to autophosphorylation of FAK at position Tyr397 and induced GTP-loading of Ras. Furthermore, IL-8 production and invasion induced by YadA were strongly reduced in FAK- and c-Src-deficient cells and in cells overexpressing dominant interfering forms of FAK, c-Src or Ras. We also demonstrate that YadA activates the Ras-dependent Raf-MEK1/2-ERK1/2 pathway and mitogen-activated protein kinases (MAPKs) p38 and JNK. Moreover, inhibition of ERK1/2 by pharmacological agents or overexpression of dominant negative FAK, c-Src or Ras abrogated IL-8 release, whereas invasion remained unaffected. In contrast, actin polymerization and phosphatidylinositol 3-kinase (PI3K) activity is essential for YadA-promoted cell entry, but not for cytokine secretion. We conclude that YadA triggers FAK-Src complex formation and subsequent Ras activation, which leads to the stimulation of MAPKs-dependent IL-8 production or to PI3K-dependent invasion.
