Figure 1From: Differential expression and function of breast regression protein 39 (BRP-39) in murine models of subacute cigarette smoke exposure and allergic airway inflammationCigarette smoke and HDM induce chitinase expression in the lung. BALB/c, C57BL/6, and CD1 mice were exposed to room air (white bar) or cigarette smoke (black bar) for four days. (A) Total cell numbers (TCN), mononuclear cells (MNC), and neutrophils (NEU) in the BAL fluid were obtained. (B) BRP-39 and AMCase levels were assessed by ELISA. (C) BALB/c mice were challenged with saline (white bars) or HDM (grey bars) for 2 weeks and AMCase and BRP-39 levels were assessed by ELISA in lung homogenates. n = 5, data shown are representative of two separate experiments, * indicate P < 0.05.Back to article page
