Sanja et al. studied the possible effect of statin therapy on the expression of inflammatory cytokines involved in COPD; for example, IL-1β, IL-2, IL-4, IL-8, IL-10, IL-12p70, and TNF-α and the possible associations between cytokines and BMI [67]. The gene discussed is CXCL8; the disease is chronic obstructive pulmonary disease.
