From: High-density lipoproteins suppress Aβ-induced PBMC adhesion to human endothelial cells in bioengineered vessels and in monoculture

Fig. 2

Aβ40 and Aβ42 induce PBMC adhesion to ECs, which is suppressed by HDL. HUVEC (a-b) or hCMEC/D3 (c-d) were primed with 100 μg/mL of HDL and stimulated with 0.1 μM a, c Aβ40 (light grey) or b, dAβ42 (dark grey) monomers for 3 h. Fluorescently labelled PBMC were allowed to adhere to stimulated cells for 3 h followed by washing, fixation, imaging, and counting. hCMEC/D3 were primed with either 100 μg/mL of HDL or 50 μg/mL or 100 μg/mL lipid-free human apoA-I for 2 h followed by stimulation with 0.1 μM e Aβ40 (light grey) or f Aβ42 (dark grey) monomers for 3 h. Cells were washed, imaged and counted as above. Graphs represent mean ± SD of adhered PBMC relative to vehicle control from at least 3 independent trials where * p < 0.05, **p < 0.01, ***p < 0.001 versus vehicle, § p < 0.05, §§ p < 0.01 versus Aβ
