IL1RN and infection: On assessing the patterns of inflammatory/anti-inflammatory cytokine gene expression, we found that the expression levels of IL-6 (Il6), IL-1β (Il1b), and IL-17A (Il17a) were significantly reduced by the MC-SeCs, whereas the expression of anti-inflammatory mediators, such as Ido1, Il10, and Il1rn, were significantly increased during the post-infection period (Figure 1G).
