CXCR3 and rheumatoid arthritis: Previously, Rossol et al have shown that Th17 cells correlate with the intermediate monocyte subset in patients with established RA [19] but in this study only a trend was found, which might be explained by differences in disease duration and treatments in this cohort compared to that in Rossol et al. To summarize, these findings show for the first time an association between proportions of intermediate monocytes and CXCR3+ Th17 cells in RA patients with early untreated disease.
