Signal transduction in Campylobacter jejuni-induced cytokine production.
Campylobacter jejuni is the leading cause of food-borne illness in the USA and one of the most common causes of diarrhoea worldwide. Central to its pathogenicity is its ability to induce the production of proinflammatory cytokines such as interleukin (IL)-8 in intestinal epithelial cells. Here, we demonstrated that C. jejuni infection of intestinal epithelial cells results in the activation of ...
متن کاملThe two-component signal transduction system RR06/HK06 regulates expression of cbpA in Streptococcus pneumoniae.
Streptococcus pneumoniae encounters a number of environmental niches in the body, including the nasopharynx, lungs, blood, middle ear, and brain. Recent studies have identified 13 putative two-component signal-transduction systems in S. pneumoniae, which are likely to be important for gene regulation in response to external stimuli. Here, we present conclusive evidence for the regulation of cho...
متن کاملTwo-component signal transduction.
Most prokaryotic signal-transduction systems and a few eukaryotic pathways use phosphotransfer schemes involving two conserved components, a histidine protein kinase and a response regulator protein. The histidine protein kinase, which is regulated by environmental stimuli, autophosphorylates at a histidine residue, creating a high-energy phosphoryl group that is subsequently transferred to an ...
متن کاملThe Nla28S/Nla28 two-component signal transduction system regulates sporulation in Myxococcus xanthus.
The response regulator Nla28 is a key component in a cascade of transcriptional activators that modulates expression of many important developmental genes in Myxococcus xanthus. In this study, we identified and characterized Nla28S, a histidine kinase that modulates the activity of this important regulator of M. xanthus developmental genes. We show that the putative cytoplasmic domain of Nla28S...
متن کاملThe Role of Campylobacter Jejuni in Campylobacteriosis
Campylobacter jejuni is a Gram negative, curved, motile, thermophilic and microaerophilic bacillus in Campylobacteriaceae family, which is one of the main causes of enteritis in human named campylobacteriosis. The main reservoir of Campylobacter jejuni is the alimentary tract of animals, especially chicken and turkey. Consumption of semi-cooked chicken meat, raw milk and unchlorinated water are...
