Figure 3From: β2-agonists promote host defense against bacterial infection in primary human bronchial epithelial cells SPLUNC1 protein levels in the apical supernatants of cultured bronchial epithelial cells. Cells from normal subjects (n = 8) were treated with Mycoplasma pneumoniae (Mp, 1 CFU/cell). Both (R)-albuterol [(R)-alb] and racemic albuterol [Rac-alb] significantly increased SPLUNC1 levels. (R,R)-formoterol [(R,R)-form] and racemic formoterol [Rac-form] marginally increased SPLUNC1. The red horizontal bars represent means of data under each cell culture condition.Back to article page
