Fig. 7From: Pro-inflammatory TNFα and IL-1β differentially regulate the inflammatory phenotype of brain microvascular endothelial cellsTNFα and IL-1β treatment causes acute reduction in the endothelial barrier resistance. ECIS-Ztheta technology was used to measure the barrier tightness, represented as barrier resistance. The arrow represents the time of cytokine addition, and the colour-coded key details the respective treatments. The TNFα responses are shown in the upper graph with the IL-1β responses shown in the lower graph. Each curve represents the mean of 4–6 wellsBack to article page
