Figure 2From: Brain pericytes increase the lipopolysaccharide-enhanced transcytosis of HIV-1 free virus across the in vitro blood–brain barrier: evidence for cytokine-mediated pericyte-endothelial cell crosstalkEffects of Pericytes on LPS-induced alterations in I-HIV permeability (Pe) and transendothelial electrical resistance (TEER). Upper panel: LPS increased I-HIV transport across the monolayers in comparison to respective controls (* p <0.05; ** p <0.01; *** p <0.001). Pericytes enhanced the effect of any given dose of LPS on HIV-1 transport (#p<0.05; ##p<0.001). Lower panel: LPS decreased TEER (***p<0.001) with pericytes producing no modification of that effect.Back to article page
