Figure 3From: 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 crosstalkExpression of cytokines by pericytes. Constitutive expression of seven cytokines was found in the control group with increased expression of these and induction of two others after addition of LPS. GM-CSF: granulocyte-macrophage colony-stimulating factor, IL-1α: interleukin-1 alpha, IP-10: interferon-inducible protein-10, KC: keratinocyte chemoattractant, MCP-1: monocyte chemoattractant protein-1, RANTES: regulated upon activation, normal T-cell expressed and secreted.Back to article page
