Proinflammatory cytokines involved in activation and recruitment of immune cells to the site of infection (IL-5, IL-6, IL-8, IL-22, IL-26 and IL-27, SELL, RETN and PLUNC) and the anti-inflammatory cytokine IL-10 genes were up-regulated in ZEBOV-infected lungs (Table 3). This evidence concerns the gene IL5 and infection.
