Interleukin 8 (IL-8) is a potent neutrophil chemoattractant and activator. Two IL-8 receptor subtypes, A and B, are expressed in neutrophils. In this work, we analyzed the role of the C terminus domain of the IL-8 receptor on the signal transduction and receptor internalization mechanisms. The IL-8 receptor A was tagged with an epitope corresponding to the(More)
Interleukin-8 (IL-8) is a potent inflammatory mediator that belongs to the family of C-X-C chemokines. IL-8 promotes the activation and the extravasation of circulating neutrophils to the site of inflammation. Two IL-8 receptor isotypes (type A and B) are identified in human and rabbit neutrophils. IL-8 receptors belongs to the superfamily of(More)
The interleukin-8 receptors (CXCR1 and CXCR2) are specifically expressed at high levels in cells of the neutrophil lineage. In this work we identify promoter elements of the CXCR1 gene and the ets family transcription factor PU.1 as a major regulator for activation of the CXCR1 promoter. We first showed that the upstream sequence of CXCR1 (-800 to +86 base(More)
Interleukin-8 (IL-8) mediates the transendothelial migration and activation of neutrophils to the site of inflammation. Two human IL-8 receptor isotype (A and B) and one rabbit IL-8 receptor isotype (A) cDNAs have been previously cloned and characterized on the basis of their pharmacological profile. Human and rabbit IL-8 receptor subtype A binds IL-8 and(More)
The putative role(s) of a mechanically gated (MG) cation channel in Xenopus oocyte growth, maturation, fertilization and embryogenesis has been examined. Using a pharmacological approach, we have tested the effects of the MG channel blockers, gadolinium, gentamicin and amiloride on the above developmental events. Our results indicate that oocyte maturation,(More)
