However, absolute levels of secreted TNF‐α, IL‐22, IL‐18, TRAIL, and ENA‐78 were still higher in LPS‐stimulated IBD compared with LPS‐stimulated non‐IBD tissue slices, which is likely representative of an increased presence of proinflammatory tissue‐resident cells such as macrophages. The gene discussed is IL18; the disease is inflammatory bowel disease.
