Abstract
ABSTRACT
Campylobacter jejuni
is a common cause of diarrhea in humans. While the pathogenic mechanisms of
C. jejuni
are not completely understood, host inflammatory responses are thought to be contributing factors. In this report,
C. jejuni
81-176 is shown to up-regulate chemokines essential to inflammatory responses. Growth-related oncogene α (GROα), GROγ, macrophage inflammatory protein 1, monocyte chemoattractant protein 1 (MCP-1), and gamma interferon-inducible protein 10 (γIP-10) mRNA transcription in INT-407 cells was enhanced within 4 h of bacterial exposure. Infection with viable campylobacters was necessary for sustained chemokine transcription and was NF-κB dependent. GROα, γIP-10, and MCP-1 chemokine secretions were confirmed by immunological assays.
