Interleukin (IL)-1β and cyclooxygenase (COX)-2 gene expression in the upper airway mucosa following injury. (A) CO2 laser injury triggers a time-dependent upregulation of both genes in the subglottic mucosa. (B) CO2 laser injury triggers the upregulation of both inflammatory genes in mucosal regions adjacent to area of direct injury Statistical significance is indicated by * representing P <.05 compared to sham values. SG = subglottis, VF = vocal fold, TR1 = proximal trachea, TR2 = distal trachea.
