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

Figure 5

Cytotoxicity of BEAS-2B exposed to ADE/non-ADE PM₁₀ organic extracts from the urban site after ENX inhibition with Polymyxin B (PMB). A value <80% was considered cytotoxic. The positive control (+CNT) of toxicity and negative controls are DMSO at 0.1% and PMB at 10 µg/mL. Bars represent mean cell viability ± SEM, of three independent experiments. Asterisks above line represent statistical significance between adjacent columns.
