Furthermore, thalidomide reduces lipopolysaccharide‐stimulated release of TNF‐α, IL‐8, and IL‐18 (‘necrotic’ cytokines), but not IL‐6, IL‐10, and IL‐12 (p70) (‘inflammatory’ cytokines) from alveolar macrophages in patients with interstitial lung disease.39 The gene discussed is IL18; the disease is interstitial lung disease.
