Figure 6. VBP15 reduces basolateral cytokine secretion from human bronchial epithelial cells obtained from asthmatic patients.

Figure 6

HBE cells from 3 separate human donors were pulse-treated with VBP15 (10 µM) or vehicle control (DMSO). Basolateral surface supernatant was tested for the presence of TGFβ1 (left panel) and IL-13 (right panel) by flow cytometric bead array. Bar graphs represent mean (±SE) concentration values. **, p<0.01 compared to vehicle control with n = 3 donors. N.D. = Not Detectible (lower limit of detection = 4.5 pg/ml).
