CD14 and rheumatoid arthritis: For instance, Müller et al. reported that 7419 lncRNAs were detected in CD14+ monocytes isolated before and after IL-6 or TNF-α inhibition in RA, among them, only 85 lncRNAs examined exhibited up-regulation and down-regulation by anti-cytokine treatment initiated, and none of lncRNAs identified showed a similar pattern in response to IL-6 versus TNF-α inhibition [53].
