Cpg stimulation of human monocytes

WebCrohn’s disease (CD) is a multifactorial incurable chronic disorder. Current medical treatment seeks to induce and maintain a state of remission. During episodes of inflammation, monocytes infiltrate the inflamed mucosa whereupon they differentiate into macrophages with a pro-inflammatory phenotype. Here, we sought to characterize the … WebApr 15, 2003 · In this study, we investigated CpG-dependent IP-10 production. CpG-A ODN were found to be potent inducers of IP-10 secretion, effecting pDC directly, while in monocytes the effect was indirect and mediated by pDC-derived IFN-α. We found no evidence for direct stimulation of highly purified human monocytes by any CpG ODN.
