Additionally, previous studies have demonstrated that COPD exacerbations are mainly associated with aggravated airway inflammation, such as increased numbers of inflammatory cells, including WBCs and neutrophils, and increased levels of acute inflammatory biomarkers, including IL-1β, IL-6, TNF-α, IL-10, CRP, and SAA [8, 11, 33–36]. The gene discussed is IL1B; the disease is chronic obstructive pulmonary disease.
