Linking Endotoxins, African Dust PM₁₀ and Asthma in an Urban and Rural Environment of Puerto Rico

Figure 8

Nuclear factor kappa B (NF-κB) activation measured in BEAS-2B exposed for 4 hrs to ADE/non-ADE PM₁₀ organic extracts from the rural and urban sites at 10 µg/mL and 5 µg/mL, respectively, with and without ENX inhibition by Polymyxin B (PMB) at 10 µg/mL. Bars represent mean transcription factor activation ± SEM, of three to four independent experiments. Individual asterisks represent statistical significance compared to DMSO and those over line significance between adjacent columns.
