Figure 7From: Diesel exhaust particles modulate the tight junction protein occludin in lung cells in vitro TNFα release in EC mono- and triple cell co-cultures. TNFα release in mono-cultures (A) and triple cell co-cultures (B) upon exposure to DEP for 24 h. TNFα concentrations were expressed as mean ± SD of 4-5 experiments. DEP treated EC mono-cultures and the triple cell co-cultures showed no difference in TNFα concentration in comparison to the respective untreated cells. No differences between mono-cultures and triple cell co-cultures concerning TNFα levels were found. LPS stimulated cultures were used for the positive control.Back to article page
